Upstream news Ding Ruyao

Not long ago, "Subject 3" exploded, and this heat is still fermenting, and it will undoubtedly become a footnote at the end of 2023. In domestic short video platforms, the number of topics played has reached nearly 12 billion; At the same time, "subject three" has also spread abroad, and foreigners of all colors can be seen dancing "subject three" almost everywhere on social platforms.

"Subject 3" is said to have started from a scene where many people were singing and dancing at a wedding in Guangxi. Some people think that it is called "subject three" because Guangxi people have to go through three exams in their lives: singing folk songs, nagging rice noodles and dancing, so they use the metaphor of driver’s license and call it "subject three". This kind of "birth" laid the keynote of "subject three"-a kind of creation from life and folk, which was unintentional, but the effect was unexpected. Today, we will talk about this unexpected explosion.

Dance has natural entertainment and appreciation. In all kinds of dance types, whether it is solo dance, duet dance or group dance, emotion and beauty can be conveyed in behavior and action, so as to achieve the purpose of entertainment and appreciation. "Subject III", with its unique dance form, has brought people richer experiences, such as ankle inversion, waist twisting, hip swinging and hand waving, which makes the dance younger, more dynamic and more entertaining. "Subject 3" doesn’t even belong to any kind of dance type, so you don’t have to stick to the specific dance posture, just stretch your limbs and twist your body at will; Don’t stick to the location, just follow the rhythm, feel it, and jump anytime and anywhere; You don’t have to stick to clothes, and you don’t have a sense of "disobedience" if you are casual or in a suit. This feeling of not sticking to traditional rules and constraints constitutes the simplest and purest happiness of "subject three", which makes people who jump happy and people who watch videos can also get a happy experience.

If happiness is the gene of "subject three", then the emotional resonance is the communication code that is constantly formed through the short video platform. Everyone can imitate, and everyone can participate. In recent years, whether it is the dubbing template of "My surname is Shi" and "My surname is Ha" that became popular on short video platforms, or the magic songs of "My Yunnan, Yunnan Nujiang", or the earlier "Jiangnan Style" and "Shoumai Culture", which has been in high popularity, it seems that there are all of them together with today’s "Subject 3". Yes, it is these earthy dance steps and slightly noisy music that have captured the psychology of people all over the world. While relaxing oneself and venting emotions, it also expresses a unique feeling and sense of belonging, and this resonance comes from life and focuses on every ordinary person.

In fact, "Subject 3" is a key, which opens a key to popular culture in the era of short video: there is no shortage of the form of spring snow and the content of Liba people. Today, when "Subject Three" becomes a hot stem of "brainwashing", this trend is gradually evolving into a grassroots fashion. When some people disdain that grassroots culture is full of strong local flavor, naturally some people praise it as "grounded", which is a kind of civilian culture and is loved by the public. Today, grassroots culture is no longer "difficult to be elegant". With the continuous popularization of short videos, where are the preferences of ordinary people and where are the hot spots? The choice of "grounding gas" has become the mainstream and has been respected and loved by more people.

The culture of a society, like a banyan tree, is flourishing with numerous drooping "breathing roots". And these "breathing roots" may come from the people, but also have interesting creations worthy of appreciation. They are grounded and can absorb the nutrients of life; They can breathe and breathe the fragrance of life. More importantly, they have propped up the tree of cultural prosperity and given cultural communication a new outlet and carrier. From this point of view, a limited carnival and a rational and inclusive view of local culture are the attitudes that should be taken today when multi-cultures blend.

On September 26th, Jetway Traveler officially went on the market, with a price of 1399-184900 yuan, showing the style of hard-core SUV and equipped with XWD intelligent four-wheel drive system.

Jetway Traveler is positioned as a medium-sized SUV, and its design adheres to the concept of hard-core SUV. Its rectangular headlight group and the brand English logo "JETOUR" embedded in the black air intake grille show personality, and the large front bumper reserves the eye-catching trailer hook position. In terms of body size, the length, width and height of the traveler reach 4785*2006*1880mm and the wheelbase is 2800 mm.

The side of the traveler’s body is outlined in a straight line, emphasizing the identity of the hard-core SUV. The wide side pedals are connected with the blackened wheel arch, and the exhibition car is equipped with original AT all-terrain tires. The rear door adopts side opening mode, and the rear door is equipped with an indispensable spare tire.

In terms of interior, Traveler is unique, abandoning the existing design of Jietu family and adopting a brand-new floating central control screen and embedded LCD instrument panel to make the interior layout more concise. There are thick handrails in the central armrest area, and the front A-pillar is also equipped with handrails to assist boarding.

In terms of power, Voyager is equipped with a 2.0T+8AT power combination, with a maximum power of 187kW and a peak torque of 390 N m.. As a hard-core SUV, travelers are also equipped with XWD intelligent four-wheel drive system, and the driving form can be adjusted to adapt to various road conditions through the knob behind the gear handle. In addition, in order to meet the diverse needs of consumers, Traveler also provides a plug-in hybrid version with a 1.5T engine, matching Chery’s own 3-speed DHT transmission.

　　[car home Information] (|), a car that has been on the market for half a month but is still worth talking about. After all, before looking up to the ground, it is basically a collection of BYD’s top technology achievements at this stage.

　　Its new technology, "Fast Charge with Two Guns", attracted the comments of friends and business executives: "Cool is cool, but …".

　　Its assisted driving level is in line with the first echelon such as Wei Xiaoli Huawei, which makes Di Fen proud.

　　Its cloud chariot -A was well received, and even the well-known roll king Zhang Chaoyang commented on it as "a roll to the end".

　　　To sum up, today, let’s not talk about rhetoric, but order dry goods, and look at the three core highlights of N7, which are also controversial points-Double gun fast charging, assisted driving and cloud chariot technology,Look at the magic market with 300,000-350,000 volume kings. Is Tengshi N7 playing well?

■ Fast charging of double guns is not a technical problem, but actually a "moral problem"?

　　The media person @ 中中中中 commented on the double-gun fast charge: "This is a philosophical question whether a person can occupy two toilets at once with two bottoms. Very profound. ". I think it is very accurate, so I quoted it directly. The following is a simple popularization of this technology. Let’s see if this evaluation is correct.

　　On the issue of fast charging of pure electric vehicles, major manufacturers have rolled up the high-voltage and high-rate battery solution of "800V+3/4C battery" in unison, and the representative models are G6 and G9 owned by Tucki, which together can achieve the maximum charging time of 5 minutes and battery life of 200 km (data of S4 overcharge of G9 4C models). It is officially claimed that the maximum charging power of 4C battery can reach 480kW, and 3C can also reach 280kW (S4 super-charged pile is required).

"Publicity map of G9"

　　However, BYD just didn’t take the usual road, and put a "double-gun fast charging" technology on Tengshi N7. The "double-gun fast charging" is not a fast charging and a slow charging at the same time, but a fast charging port on the left and right and two fast charging ports at the same time. If you don’t know, you can look at the real shot of car home below.Tengshi N7 has charging ports on the left and right sides of the car body, and one side is a combination of 9-hole fast charging and 7-hole slow charging, just like ordinary new energy vehicles. On the other side is a separate 9-hole fast charge.

"One side of N7 has 9 holes for quick filling"

"One side of N7 has 9-hole fast filling port +7-hole slow filling port"

　　In terms of data, the official claims to charge 300km for 15 minutes, with a maximum power of 230kW for two guns and 150kW for a single gun. Of course, this power also needs the support of the station. You should not fantasize about the power of 150kW on the pile with a calibration of 60kW in the State Grid.

　　The technology of fast charging with two guns is not difficult to realize. The pure electric version of Tengshi D9 is equipped with this technology, but the maximum power that N7 can support has increased.Double-gun fast charging has long been applied in new energy buses, and it is reasonable for BYD to transfer its technology to passenger cars. Weilai’s wet nurse car has also used this technology. It can even plug three guns into a car to replenish electricity, which is very overbearing.

　　The biggest problem of fast charging with two guns may be "morality". This charging mode requires one person to occupy two piles. As we all know, charging piles are scarce resources. Especially on the high-speed holidays, some grumpy brothers have to scold a few words when they look at the ideal or plug-in cars occupy one pile to charge. Excuse me, are the oil in your tank and the engine in the front cabin furnishings? Let them see you take advantage of the situation. You can’t fight, can you?

　　Imagine this scene, because of the length of the charging cable, you may need to park your car between two charging parking spaces, accept the eyes of the car owners, and some good things will ask you a few words, which is simply stinging for me. In addition, there is a soul question-does ——App support double opening? This question is similar to whether a computer can log in to two WeChat, which deserves serious consideration. Of course, at present, some apps such as special calls support double opening, but some don’t. Therefore, it is recommended that you bring a lively friend when charging, which can not only help scan the code, but also charge the car owners with two guns.

　　As for the fast charging power of two guns, the measured data of car home on D9 show that the maximum charging power on a 120kW charging pile is 101.8kW when the power is below 80%, and the power drops to 55kW when the power is above 85%. Measured on N7, when the battery charge is 39%, the power reaches 176.7kW. In addition, some users actually measured that N7 was charged from 20% to 80%, and it took 21 minutes for a single gun and 14 minutes for a double gun.

"Measured data of car home on D9"

"Measured data of car home on N7"

　　We emphasize that the charging speed and power are related to many factors, such as the situation of the station and the battery capacity. Generally, the highest power advertised by the manufacturer cannot be reached, and everyone’s test data is not necessarily the same. Tesla explained this problem clearly, so you can refer to it.　　　

　　

　　To sum up, the advantages and disadvantages of "high-voltage fast charging" and "double-gun fast charging" are theoretically better than that of "double-gun fast charging", but it needs the support of exclusive charging piles and batteries, which is difficult to spread in a short time. For example, Tucki’s S4 is overcharged, and the P7 of the non-800V platform cannot reach that high power; Even the Tesla V3, which is paved more now, cannot be compared with ordinary charging stations in quantity. The fast charging with two guns can make better use of the resources of the station, and can improve the charging speed under the same conditions without modifying the station. In other words, if everyone is in the same State Grid station, the charging speed of two guns together is better than Xiaopeng G9. After all, 800V has nothing to play in this scene.

　　As for some comments on the internet, it is actually a question of "ass decides head", so you can refer to it selectively. For example, Zhao Changjiang of Tengshi once spoke out, "Charging 800V has been fooled by some enterprises in the industry." He said that BYD can achieve a charging peak of more than 700V in 2018, but double-gun fast charging can double the charging efficiency even on a 240V ordinary public charging pile.

　　He Xiaopeng and Li Xiang, who are fast charging the Party, are naturally fans of 800V, and their attitude is shown by the over-charging stations and overwhelming publicity.

　　　Shen Fei, a seemingly neutral Weilai executive who mainly changes electricity, commented that the double-gun fast charging is "in practice, it is not as convenient as expected" based on the car experience of his own wet nurse car.“Being cool is cool, but there are not many occasions that can make you cool.”。 At the same time, he also believes that the charging power is not a problem, and the voltage is not a problem. The key is "whether users have demand or not, and whether enterprises are willing to invest huge sums of money to build super-filled piles".

　　In other words, Tucki and Ideality chose to build their own overcharge station, and Weilai chose to build and replace the power station. BYD didn’t have these ideas, but also hoped that your recharge would be more comfortable and smooth, so it arranged a double-gun quick charge. Everyone is trying their best to serve the owners and help the rapid development of new energy vehicles.

　　At this point, the discussion on "double gun fast charging" has come to an end. Do you think this technology is easy to use? How does it compare with 800V? Welcome to discuss in the comments section.　　　　　　

■ city/high-speed NOA has to wait for OTA?

　　Let’s talk about assisted driving. Now, the new car-making force headed by Wei Xiaoli is crazy with rhythm, that is, about 300,000 electric vehicles must be driven with advanced assisted driving, otherwise it will not be luxurious enough, not smart enough, and it still seems to be behind the times. At present, it has been rolled into the city NOA. And BYD, in these years, has been lacking in this respect.

　　Tengshi N7 "Tengshi Pilot" can be described as making Difen proud.This fusion scheme of laser/millimeter wave/ultrasonic radar+camera+high-precision map can provide high-speed NOA, urban NOA, AVP parking service and full-scene NOA software, which is in line with the current level of head enterprises in theory.

　　　However, Tengshi N7 can’t realize high-speed NOA at present, and it is expected to be realized in Q4., including the ability of point-to-point automatic driving at high speed and handling sudden traffic jams. By March next year, it can realize the functions of avoiding high-speed obstacle cars, driving on ramps with large curvature and parking across floors.NOA driving support in 20 cities is expected to be realized next year.

　　　At present, N7 only has high-speed ACC, lane change with lights, multi-scene automatic parking and so on.. Therefore, if you want to use NOA immediately and experience the happiness of intelligent driving, we suggest choosing Tucki or Aouita. Now they can let you enjoy NOA.

　　As for the actual experience of Tengshi N7 assisted driving, please watch the measured video of car home. To sum up briefly, the basic function is great, and I look forward to higher-level functions!

More exciting videos are all on the car home video platform.

　　　Tengshi Pilot is divided into standard and high-order, which is also very common. Basically, the number of chips and sensors is different. The standard version is equipped with 5 cameras, 5 millimeter waves /12 ultrasonic radars. The chip comes from the horizon, and its functions are the ACC mentioned above. Now people generally call them "L2". The high-end version needs to spend 23,000 yuan (limited time discount) to choose and install, and gave a NVIDIA Orion-X with a computing power of 254TOPS. This chip is also an old friend of everyone and is familiar with it; As well as a camera and two laser radars, the functions include high-speed NOA, urban NOA, HPA memory parking, AVP parking service and so on.According to Zhao Changjiang, 20% of the scheduled car owners chose this set of advanced assisted driving.

　　Regarding this set of assisted driving, because it has not yet landed, everyone is concerned about some theoretical issues, such as the low-priced double horizon journey 3, with a computing power of 10TOPS. At this time, someone jumped out and said, why don’t more than 300,000 cars even give a journey 5? You see, the low match of people’s ideal L7 is Journey 5! Finally, 128TOPS! However, Double Journey 3 has also been put into use in many models, such as Nezha S and Deep Blue SL03. It is no problem to realize the basic functions, and it can be used in other places with some cost savings.

　　There is another melon. The N7 is a very rare vehicle that uses a single NVIDIA Orin-X to realize a series of high-order driving assistance functions (we have reason to suspect that dual Orin-X will be expected). At present, manufacturers that can realize NOA in cities, except for Huawei’s Wenjie and Aouita, all adopt the scheme of two Orin-X, and Weilai ES6 even rolled out four Orin-X, which is not low in cost estimation … So the N7 is in. However, in view of the fact that canoe Zhixing has been able to make a city NOA (no mass production) on a journey 5(128TOPS), I think an Orion-X (254 TOPS) is not impossible. The partner chosen by BYD is Momenta, a supplier who has worked with Zhiji and has rich experience.

　　　At the launch conference of Tengshi N7, BYD also released the "Eye of God" high-order intelligent driving system, which has several innovations, such as the integration of the vehicle’s perception and execution mechanism with software, and a set of hardware, that is, the vehicle-mounted computing platform and the self-developed software vehicle control system BOS.

　　The on-board computing platform is not just the NVIDIA chip, it contains hardware and software. We can watch the video released by BYD. The on-board computing platform is a bit like a circuit board welded by engineering students, which contains hardware and software, and the hardware integrates multiple CPUs and GPUs. There are more layers of software, and BOS is one of them.

More exciting videos are all on the car home video platform.

　　　Having said so much above, I want to emphasize BYD’s self-research ability. At present, automobile manufacturers have different degrees of participation in the self-research of in-vehicle computing platforms. For example, Tesla can develop its own operating system, functional software and even chips. Tucki has realized self-research of various functions, and some manufacturers choose to package suppliers directly. At present, a trend is that as a vehicle manufacturer, it is an ideal path to start self-research from the development of application layer software, then go deep into the self-research of system software architecture, and then develop its own special chip like Tesla to realize self-research of software and hardware. BYD has achieved self-research of operating system, which is still relatively excellent.

　　　Speaking of a thousand words and ten thousand words, the assisted driving thing is still worth seeing in the actual measurement. We also hope that Tengshi will quickly push the advanced driving assistance and prove its strength with the measured data.　　　　

■ Can Yunqi -A compare with the magic carpet of Mercedes-Benz?

　　　If you are a qualified "Difen", you are certainly no stranger to Yunxiao. In April this year, the cloud system was released.It includes four sets of body control systems with different orientations (Yunqi -C, Yunqi -A, Yunqi -P and Yunqi -X).

　　Here we focus on Tengshi N7′ s first ride.Yunnian -A, this is an intelligent air body control system.It is Yunnian -C (Variable Damping Shock Absorber) with air spring, which can change the suspension height, spring stiffness, shock absorber damping and active adjustment of seat wing. We know that the subsequent Yunqi -A supports multi-cavity air springs, and can be monitored by OTA camera and lidar, which is similar to the active sensing function of Mercedes-Benz "magic carpet".

　　In recent years, domestic new energy vehicle companies have been involved in a crazy way, and more than 300,000 vehicles can also enjoy the beauty of air suspension, such as Krypton 001 (Weiback single cavity air suspension), Tucki G9 (Weiback double cavity air suspension) and Zhiji LS7 (mainland single cavity air suspension); Coupled with the efforts of domestic products Kong Hui (ideal supply) and Baolong (supply Tengshi N7), air suspension is almost "flying into the homes of ordinary people", and people are increasingly fond of discussing air suspension.

　　Not long ago, there was a great controversy about whether the ideal L9 suspension could be called "magic carpet". The reason is that some people think that the ideal L9 system can’t scan the road conditions in advance and actively adjust, but passively adjust, which is simply touching the porcelain magic carpet. Some people think that no one has set a standard to say what a magic carpet is. Why can’t an ideal say that it is a magic carpet?Let’s talk here. Do you think N7 can compare with Mercedes-Benz’s "magic carpet" after OTA camera and lidar detection?

"The ideal" magic carpet "hangs in the air"

"Magic carpet technology of Mercedes-Benz"

　　In addition, the single/double-cavity air spring is also the focus of discussion. For example, Tucki G9 uses the double-cavity air suspension from an old foreign supplier, which gives almost the same price at once, but the ideal and momentum of using the domestic single-cavity spring N7 is shocked. Of course, from the known information, the ideal and soaring double-cavity suspension and sensing technology are working overtime.

　　The ideal engineer said well in an interview with the media, "Under the same price range, if you don’t short the spring, the product will not be competitive;" Today, when you use a single-cavity air spring, you see that others use a double cavity. Everyone doesn’t care what the double cavity and the single cavity bring to the car. Even if they are equivalent, they will feel that the double cavity has one more cavity than others, and the performance is good. It is rolled up. " In fact, we consumers should focus on the actual experience rather than focusing on single cavity or double cavity, magic carpet or CDC. The following is the driving experience video of Tengshi N7, which you can refer to or test drive yourself.

More exciting videos are all on the car home video platform.

■ A small egg-6 nm chip

　　　Tengshi N7 conference site, there is also a fun little egg-car chip. This chip is special in the 6nm process. We know that the Qualcomm Snapdragon 8155 used by high-end players at present is 7nm, while the Qualcomm Snapdragon 8295, the next-generation product used for integration, is 5nm. So what is this magical "6nm" process chip?

　　At that time, everyone generally speculated that it was a domestic chip, but later, Zhao Changjiang said in an interview with the media that it was actually a customized Qualcomm chip, which focused on the whole ecology and was suspected to be pluggable, that is, it was very convenient to replace it with a stronger chip later.

　　Tengshi N7 has six screens, which can be driven by this chip. Compared with 8155, its data also has obvious advantages. At present, some car winder manufacturers, such as Ideal, use double 8155. However, for BYD, a conservative car company, Tengshi D9 still uses Qualcomm 7325 when people are crazy about Qualcomm 8155. Such a customized chip can also show sincerity. As for the specific performance and characteristics of the chip, we expect Tengshi to be revealed slowly.

　　Tengshi N7 is a car worthy of a special book in terms of significance, products, technology and market. This paper only focuses on its three product points, without much analysis on its significance to BYD and Tengshi, and the future after entering the highly competitive Red Sea market. We also welcome more friends who are interested in this car to actively participate in the discussion in the comment area. (Text/car home Xing Yueyang)

As a well-deserved leader in the domestic leather industry, Great Wall pickup truck has ranked first in the sales volume of the same industry for 22 consecutive years. Its products not only have good sales results in China, but also are loved by consumers in overseas markets. Today, the cumulative global sales volume of Great Wall pickup truck has exceeded 1.8 million units, and its influence is self-evident. With the upgrading of Fengjun series, and the great wall gun, commercial and off-road pickup trucks, the great wall pickup truck is moving towards becoming the top three pickup truck brands in the world alongside Ford and Toyota.

On September 12th, the highly anticipated diesel 8AT for the Great Wall Gun passenger/commercial pickup truck was officially launched, completing the final puzzle of the Great Wall Gun Fuel Edition series. Since then, the Great Wall pickup truck will form a more powerful and complete product pedigree, which will continue to lead the pickup truck industry in China to a new high. So, what is the product strength of diesel 8AT for the Great Wall Gun/commercial pickup truck? Let’s take a look at its actual performance.

　

The exterior interior is the same as the gasoline version.

This time, we test-drive two cars, namely, the pickup truck diesel 8AT and the commercial pickup truck diesel 8AT, which have just been listed. In terms of styling interior, the new car has not changed compared with the current models on sale. The biggest change is that it has been equipped with a 2.0T diesel +8AT gearbox power combination. Therefore, this test drive only briefly reviews the appearance and interior design of the Great Wall Gun, focusing on the power system and driving experience.

In terms of configuration, there is not much difference between the Great Wall gun pickup truck and the commercial pickup truck. It has many high-end configurations such as 9-inch central control large screen, Bosch version 9.3 ESP, keyless entry/one-button start, tire pressure monitoring, reversing image, and the only boarding ladder at the same level, which ranks among the top in the domestic pickup truck industry. However, the commercial gun has reduced the configuration such as front radar, 360 panoramic image, L2 autopilot system and LCD instrument panel, further reducing the cost of the whole vehicle and making it more in line with the needs of commercial users.

In addition, the changeable rear seat form of the Great Wall Gun is also the characteristic that the cockpit is different from the previous pickup truck products. In the previous pickup truck models, the second row of the backrest or cushion can only be lifted up or down as a whole, which has great problems in the coordination of space utilization. However, the backrest and cushion of the second row of the Great Wall Gun can be lowered or lifted up according to the ratio of 4:6 and can be directly fixed, making the use of the rear space more convenient.

In a word, the exterior design and interior configuration of Great Wall Gun are quite excellent, which is not much different from middle and high-grade luxury. It has upgraded the overall product strength of domestic pickup trucks to a higher level, which is very suitable for the passenger demand of pickup trucks emerging in the domestic market, and can well meet the daily car demand of passengers, elite business people and private owners, taking into account the passenger business experience.

Diesel 8AT is stronger than gasoline.

The Great Wall gun passenger/commercial pickup truck diesel 8AT we test-drive is equipped with the same power system. The engine is a 2.0T diesel turbocharged engine of GW4D20M, with a maximum power of 120kW and a peak torque of 400 N m. The transmission system is matched with ZF 8AT manual transmission, and equipped with a four-wheel drive system with rear axle Eton electronically controlled differential lock. The overall hardware configuration is very attractive. The power system of the diesel version of Great Wall Gun is among the best in domestic pickup trucks, and it has the largest torque among domestic pickup trucks at present.mass productionDiesel pickup truck is also the first power system to push the torque of domestic pickup truck to 400N·m level.

This test drive mainly paves the road for the city, which is in line with the positioning of the Great Wall Gun Ride/Commercial Pickup, that is, the riding property is added on the basis of the utility demand of the tool car, so as to meet the high-value loading demand of the city merchants, such as wine, flowers, furniture, etc., and the household demand of the city residents, such as traveling and walking, etc., and show the dual-purpose characteristics of business and riding.

First of all, the driving experience of the diesel 8AT version of the Great Wall Gun passenger/commercial pickup truck is more exciting than that of the gasoline version. The low-torque property of the diesel engine and the adjustment of ZF 8AT gearbox make the Great Wall Gun behave more calmly than the gasoline version in the starting, acceleration and low-torque stages, with the power being stepped on, the output form is quite linear and soft, and there is not too much sense of suddenness and frustration. The adjustment of accelerator pedal and brake pedal is quite different from that of pickup trucks in the past, and the whole process is linear and efficient. With the continuous improvement and progress of Great Wall Gun models, the strength of accelerator pedal and brake and the sense of travel feedback are more biased towards passenger cars, and the light pedal and power output setback in the first test drive have been effectively improved, which can bring a good first impression to drivers.

The adjustment of the steering wheel strength of the new car is also in line with the positioning of the vehicle. The pickup truck for the Great Wall Gun is equipped with electric power steering as standard, and the steering feel is relatively light, but it does not lose the composure of a big car. The commercial pickup truck of the Great Wall Gun adopts the traditional hydraulic power steering. For the commercial version positioned for industrial and commercial use, this can effectively reduce the cost, at the same time, it can also increase the sense of control over the steering wheel and improve the stability of the vehicle during heavy transportation.

thatSecond, it must be said that with the growth of the Great Wall gun model, the Great Wall pickup truck has become more and more skilled in the configuration adjustment of this ZF 8AT gearbox. In the case of daily urban road driving, the gearbox upshifts actively, and it can be upgraded to the eighth gear at about 80km/h, and the speed is always maintained in the maximum torque output range of 1500-2500 rpm during this process, which can ensure the continuity of power. In the process of speeding up overtaking, this gearbox can also respond appropriately, and realize the power explosion by continuously downshifting. Although the downshifting process is still not as agile as that of a passenger car, it is quite excellent for a pickup truck.

And as the first domestic pickup truck product to adopt 8AT gearbox, the combination of Great Wall Gun 2.0T+8AT not only brought changes in power output mode to consumers, but also opened the prelude for domestic pickup trucks to approach passenger cars. Since then, various domestic pickup truck products exposed have taken 8AT gearbox as the main selling point, highlighting the position of the pioneer and leader of Great Wall Gun in the industry, and promoting the ride and internationalization of domestic pickup trucks.

Furthermore, the four-wheel drive system of the Great Wall Gun is also a commendable highlight. As we all know, the Great Wall Gun uses the TOD four-wheel drive of Borg Warner, that is, the torque on demand four-wheel drive. Many people think that this TOD four-wheel drive is timely and cannot provide the hard-core attributes of part-time 4wd, and is not suitable for heavy off-road and bad road scenes. In fact, this kind of cognition is biased and preconceived. part-time 4wd does have certain structural advantages, but the TOD four-wheel drive is not so unbearable, otherwise the Raptor, herdsman and Tyrannosaurus Ram 1500 will not adopt it.

Accord to that practical application, the intelligent four-wheel drive system is a special four-wheel drive mode between timely four-wheel drive and part-time 4wd. TOD system is usually driven by rear wheels, but when the road conditions change, the corresponding mode can be selected as needed to transmit torque to the front wheels to provide sufficient grip. TOD is faster and more accurate than manual part-time 4wd, and more cost-effective than full-time four-wheel drive system. At the same time, intelligent four-wheel drive is also the development direction of the automobile industry in the future. We recognize the classics of part-time 4wd system, but we also need to recognize the changes brought by the TOD four-wheel drive of Borg Warner.

Compared with timely four-wheel drive, TOD four-wheel drive provides 4L and 4H modes, which can realize driving in complex road conditions. Take the Great Wall Gun as an example. The pickup truck for the Great Wall Gun and the commercial pickup truck have four modes: 4L, Sport, Economy and Standard. The off-road pickup truck of the Great Wall Gun has three additional driving modes: snow, mud and sand. Although there is no clear 4H mode, six special driving modes except 4L can provide 4H equivalent effect and full-time 4WD effect through comprehensive regulation of engine, gearbox and 4WD system, not just adjusting the throttle response. Moreover, it is more subdivided according to the specific road conditions, which is not as fixed as the 4H in part-time 4wd. It is more effective than the four-wheel drive intervention in time, which can be said to be very simple and convenient, and is suitable for novice drivers and wider users.

The hydraulic locking of multi-disc clutch is the same. The characteristic of Ford Raptor and Ram 1500 Tyrannosaurus Rex is that there is a traditional 4H mode for everyone to choose from. Therefore, the TOD four-wheel drive of Bogwarner is relatively reliable as a whole, and it is not necessary to worry too much about the overheating problem that the majority of riders are worried about. Its durability is trustworthy. Of course, if you take the Great Wall Gun pickup truck and commercial pickup truck to cross-country, you really need to be cautious, because compared with the Great Wall Gun off-road pickup truck, the main scenes of passenger and commercial models are still urban sections and poor.

In addition, the quietness of the GW4D20M diesel engine carried by the Great Wall Gun is also quite commendable. The sound insulation performance of the Great Wall Gun diesel 8AT model is quite excellent, and the engine noise control is in place. It is difficult to intuitively feel that this is a diesel vehicle when sitting in the car. This has been reflected in the previous test drive of the Great Wall Gun commercial pickup diesel 6MT model, and it will only be felt that it is a diesel vehicle when it is occasionally accelerated at medium and low speeds and parked.

Finally, the diesel version launched this time also adopts the suspension system of the models currently on sale. The pickup truck of the Great Wall Gun is a structure of front double wishbone independent suspension+rear multi-link integral bridge-type dependent suspension, and the commercial pickup truck of the Great Wall Gun is a structure of front double wishbone independent suspension+rear leaf spring. Multi-link rear suspension can make it have better performance in comfort, which is also a major feature of the pickup truck for the Great Wall Gun, while the leaf spring rear suspension conforms to the positioning and use of the commercial pickup truck for the Great Wall Gun. There is not much difference between them in specific driving experience, but the biggest difference lies in the different degree of bumps.

And on the new car listed this time, we can see that the Great Wall pickup truck has reinforced the trailer hook of the Great Wall Gun, and the reinforcement scheme can be said to be quite reliable. We have also made corresponding explanations and reports before. The Great Wall pickup truck also stuck a trailer hook usage specification on the driver’s side, which can help the owner to better use the trailer hook for rescue, which is very intimate.

Write it at the end

The Great Wall pickup truck has always been original, putting quality first, and the propaganda slogan is "Let the pickup truck become popular", and the real basis for opening the pickup truck in spring is a product with good product strength and strong reliability. The Great Wall Gun is indeed superior to the same level products in terms of configuration, interior, appearance design and power. It is in the leading position in terms of high-grade sense and scientific sense, but it can be called a good car. Compared with Ford Raptor and Toyota Hyrax, the Great Wall Gun passenger/commercial pickup truck diesel 8AT model has been launched, and the Great Wall pickup truck product line has been improved and enhanced. In the future, the Great Wall pickup truck will try to subvert the international market structure with greater strength and become a veritable one.

　　　　The world’s first electronic computer "Eniac"

　　On February 14, 1946, at Moore Institute of Electrical Engineering, University of Pennsylvania, there was a festive atmosphere everywhere. Many guests come here with excitement, because they will attend the unveiling ceremony of the first modern electronic computer in human history. What is presented to people is a monster with a strange shape and shining all over. It is the world’s first modern electronic computer "ENIAC". This monster covers an area of 170 square meters and weighs 30 tons. At the unveiling ceremony, "Eniac" performed its "unique trick" for the guests-5000 additions and 500 multiplications were performed in one second, which was more than 1000 times faster than the fastest relay computer at that time. This perfect appearance made the guests applaud. However, who knows, in the process of the birth of this behemoth, how many people have devoted countless efforts to it!

　　A monster born of war.

　　Although the emergence of electronic computer is only 60 years, its birth is the accumulation of hundreds of years of human efforts. As early as the 17th century, a group of European mathematicians began to develop computers. In 1642, in order to assist his father, who was the director of taxation, Pascal, a 19-year-old French mathematician, successfully built the first mechanical computer with a clock gear, but he could only do addition and subtraction. On this basis, the German mathematician Leibniz invented a computer that can do multiplication and division in 1678. However, the performance of these mechanical computers is too backward to meet people’s needs. More than a hundred years later, the British mathematician Babbage designed a more advanced computer in 1822. Unfortunately, Babbage’s design could not be realized because of the limited industrial level at that time.

　　In the next 100 years, mankind has made great progress in the fields of electromagnetism, electrotechnics and electronics, laying a solid foundation for the emergence of electronic computers. After the outbreak of World War II, the U.S. Army Ordnance Department set up a "Ballistic Research Laboratory" in Aberdeen, Maryland to research and develop new artillery. The extremely heavy computing task is a big headache for the researchers there. Although the laboratory employs more than 200 computing Aauto Quicker, it is still stretched. They urgently need a new computing machine to improve work efficiency. Just when people were at their wits’ end, Dr. Moakley from Moore School of Electrical Engineering, University of Pennsylvania put forward the idea of trial-producing the first electronic computer. His idea attracted the Army Ordnance Department, who immediately asked Moore College to draw up a development plan.

　　According to the scientists’ estimation, the cost of manufacturing an electronic computer was $150,000, which was a huge sum at that time, so it was resolutely opposed by many people in the military. Seeing that the plan to develop an electronic computer is about to die, Dr. Wilbur, a famous American mathematician, firmly stood in the ranks of supporters, and he finally persuaded the US military. After more than two years of intense development, the first electronic computer finally came out on February 14, 1946. And its development funds have been increased several times, and finally reached $480 thousand.

　　This electronic computer, called "Eniac", now looks like a monster. There are thousands of electronic tubes, diodes, resistors and other components inside, and there are as many as 500 thousand welding points in the circuit; On the surface of the machine, there are meters, wires and indicator lights. What makes people laugh and cry is that it consumes more than 174 kilowatt hours, and it is said that the lights in the whole town will dim when it is used; Moreover, its electron tube burns out every 15 minutes on average, and scientists have to keep changing it in a big sweat. However, the calculation speed of "Eniac" is 200,000 times that of manual calculation and 1,000 times that of relay computer. The U.S. military has also tasted the sweetness, because it only takes three seconds to calculate the trajectory of artillery shells, while before that, it took 200 people to calculate it manually for two months. In addition to conventional ballistic calculation, it later involved many scientific research fields and played an important role in the development of the first atomic bomb.

　　On October 2, 1955, Eniak was declared "retired" and was displayed in a museum in Washington.

　　Three electronic computers compete for the title of "the first in the world"

　　Interestingly, the halo on the head of "Eniac" has been controversial for many years. In fact, quite a few people think that the "Giant" computer developed by Britain in 1943 is the world’s first electronic computer, but it has been kept secret. It was not until 1975 that the British authorities declassified the relevant files that people understood this inside story.

　　It turned out that in the Second World War, in order to decipher a mechanical code of the Germans, British intelligence agencies and mathematics,

　　With the cooperation of electronics experts, a large-scale electronic computing device was developed in 1943, and it was called the "giant" machine. Before the invention of the "Giant" machine, it took six to eight weeks for Britain to decipher the German high-level passwords, but it only took six to eight hours after using the "Giant" machine. Since it was put into use, a large number of German high-level military secrets were quickly deciphered, which greatly accelerated the process of Nazi Germany’s downfall. Because of the need of war, Britain regards it as "super secret". It is said that in order to keep secrets, Britain did not hesitate to secretly destroy 10 similar computers after the war. However, some people think that the "giant" computer is not a real electronic computer, but is between relay computer and modern electronic computer.

　　There is another saying that atanasoff, a Bulgarian-American physicist, was the inventor of the first electronic computer. As early as December 1939, he built the world’s first electronic computer, but because it was World War II, he didn’t apply for a patent or publish the information. Despite different opinions, "Eniac" is still recognized by most people as the world’s first electronic computer, and Valentine’s Day 60 years ago has been recorded in the history of human invention forever.

　　Electronic computers became famous overnight because of the presidential election.

　　At the beginning of its birth, "Eniac" could not be widely used because of its many defects. It was not until 1951 that Moakley and eckert developed UNIVAC (Universal Automatic Computer) on the basis of "Eniac" that electronic computers began to move from the laboratory to the society. Soon, an accident happened, and its popularity increased rapidly.

　　In 1952, it coincided with the American election. In order to process the election data, CBS rented UNIVAC to predict the election results. Just 45 minutes after the election, UNIVAC calculated that Eisenhower would win with an absolute advantage of 438 votes. But before the election, almost all experts and the media predicted that the two sides would be evenly matched. Therefore, the broadcasting company refused to report the prediction results of the computer. Engineers had to recalculate, but the computer still insisted that Eisenhower would win by a wide margin. When the election results were officially announced, everyone was shocked: Eisenhower actually got 442 votes, and UNIVAC’s prediction had an error rate of less than 1%! Since then, the whole world has begun to have a new understanding of the functions of electronic computers, and the development of electronic computers has entered a new era.

　　From then on to today, the development of electronic computers can be described as leaps and bounds. It is not only widely used in people’s social life, but also directly guides the development of today’s information society. There is no doubt that the electronic computer is one of the greatest inventions in human history. Nowadays, it has become an indispensable part of modern society and will continue to play an important role in the future. (Yang Honglin)

In the "Children’s Companion Home" in Nanbian Village, Gongfang Town, Le ‘an County, Jiangxi Province, the "Children’s Companion Mom" took the children to play with toys. Xinhua news agency

　　[Talking about health]

　　Magnetic buckyball, jelly-like crystal mud, luminous balloon … … These "online celebrity" toys, which have sprung up in recent years, are likely to become "sharp weapons" to hurt children. According to media reports, in the past summer vacation, many children in Guangdong, Hubei, Xinjiang and other places suffered gastrointestinal injuries due to swallowing buckyball by mistake, and even needed surgery. What other children’s toys need attention? Where are their security risks? Our reporter sorted out the consumption tips issued by the Defective Product Management Center of the State Administration of Market Supervision, selected some children’s toys that are currently popular in the market but have hidden dangers, analyzed their safety hazards, and called on the whole society to pay more attention to the safety of children’s toys.

　　My two-year-old daughter often has a stomachache recently. Her parents thought it was a gastrointestinal problem. As a result, she was sent to the hospital for examination and found that there were four intestinal perforations in her body. Parents are both afraid and puzzled. Why do children have intestinal perforation? It turned out that there was a magnetic bead toy named "buckyball" at home that was swallowed by the girl by mistake, and the hospital finally took the magnetic beads out of the girl through emergency surgery … … This is a recent report in the media. This hospital has treated 7 children who swallowed buckyball by mistake in the last month or so.

　　This is not the only report that children’s toys hurt people, and buckyball is not the only children’s toys that hurt people. Magnetic buckyball, jelly-like crystal mud, luminous balloon … … These "online celebrity" toys, which are novel or fun, are ignited by online social platforms, and often become dangerous goods that hurt children.

　　The Defective Product Management Center of the State Administration of Market Supervision is responsible for the defect investigation and public opinion monitoring of all kinds of products on the market, and issues consumption tips to recall the defective products. The reporter found that children-related products, including toys, accounted for almost two-thirds of the consumption tips released by official website. The Quality Development Bureau of the General Administration of Market Supervision introduced at the theme activity of children’s products safety education on June 1st this year that since 2008, China has carried out 1,189 recalls of children’s products, accounting for 49.6% of the recalls of consumer goods, involving nearly 6 million pieces, and one recall of children’s products is every two recalls of consumer goods on average.

　　These toys and other children’s products with defects in design or quality, in order to attract children, excessively pursue fun and ignore safety. In particular, the security risks of the novel toys that attract attention on the Internet and have the "online celebrity" effect cannot be ignored.

　　Buckyball and the small magnetic beads of the magnet pen, "wearing the intestines and breaking the stomach"

　　Buckyball is a kind of magnetic beads with a diameter of about 5mm. Many buckyball can be combined into various shapes at will with the help of magnetic force, which has been advertised by merchants as "educational toys" and is very popular with children and parents. There is also a magnet pen with a similar design with buckyball, which is also a new online celebrity product in recent years. In addition to the normal writing function, this pen is inlaid with magnets at both ends, and with matching steel balls, it can realize a variety of combined games by magnetic force. However, buckyball and the magnetic pen, which are fun and creative products, actually have great security risks.

　　The Defective Product Management Center of the General Administration of Market Supervision once published a case in which a 13-year-old boy in Guizhou sucked a magnet into his mouth while playing with a magnet pen in class, and then used another magnet to attract the magnet in his mouth. As a result, the two magnets successively entered the abdomen along the esophagus. When I went to the hospital for examination, I found that the two magnets were attracted tightly across the stomach muscle layer, and a 0.1 cm perforation was chiseled.

　　"There are not a few cases of such magnet injuries, and most of them are concentrated in children aged 1 to 10." The Defective Product Management Center of the General Administration of Market Supervision pointed out in the consumption tips that small magnetic parts such as magnetic beads are more likely to be swallowed by children by mistake, and if they enter the trachea, they will cause the danger of suffocation; If it enters the digestive tract, it will cause vomiting and abdominal pain, and it will lead to gastrointestinal damage; Especially when two or more magnets are swallowed, the magnets will adsorb each other through the gastrointestinal wall in the digestive system, and continue to generate pressure, which may cause gastrointestinal perforation or intestinal obstruction, which may be life-threatening in severe cases. In general, these small magnetic parts can only be removed by surgery, which will cause permanent damage to children’s digestive system.

　　The Defective Product Management Center of the General Administration of Market Supervision reminds that there are many kinds of magnet pens sold in the market, but most of them are three-no products. Not only do they have no factory name, address and product certificate, but also there are no warning instructions on the pen body and packaging, so the safety cannot be effectively guaranteed. It is recommended not to buy such products.

　　Borax poisoning of "mud" toys such as crystal mud should not be underestimated.

　　The charm of magnet toys lies in the creative experience of combination play, and similar to it, "mud" toys also have such functions. In recent years, all kinds of soft, sticky, jelly-like "mud" toys have become popular around campus and online platforms. They have different names, such as Crystal Mud, slime, Bubble Mud, Cotton Mud, Poke Mud and Snowflake Mud, but they have common characteristics — — Colorful, soft to the touch, can change various shapes, and can also be used to blow bubbles, draw pictures, etc., which is deeply loved by children.

　　However, they are not real mud, but are made of many chemicals. These "mud" contain a substance that may be harmful to health — — Borax.

　　According to the introduction of the Defective Product Management Center of the General Administration of Market Supervision, polyvinyl alcohol, a polymer material dissolved in water, reacts with borax (also known as coagulant aid), and the dissolved polyvinyl alcohol is pulled together by the anions of borax to form a hydrogel with a network structure; On this basis, hand sanitizer, emulsion, pigment, beads, clay, etc. are added to make various "mud" toys such as crystal mud.

　　These "mud" toys are brightly colored, similar to jelly, and usually have their own straws, which can blow bubbles nominally. When children blow bubbles with straws, the product comes into close contact with the mouth, which may lead to the risk of borax poisoning. The Defective Product Management Center of the General Administration of Market Supervision explained that borax is extremely harmful to human health. Excessive intake in a short period of time will cause nausea, vomiting, depression, convulsions, skin flushing, circulatory failure and other symptoms. Excessive intake for a long time will lead to cumulative poisoning of multiple organs, causing damage to organs such as liver, kidney, brain and lung. The toxic dose of borax is 1 to 3 grams for adults, 15 to 20 grams for adults and 5 grams for children.

　　At present, borax is prohibited as a food additive in many countries, and the intake of boron is limited. The national standard (GB5749-2006) of Hygienic Standard for Drinking Water in China stipulates that the limit of boron in drinking water is 0.5 mg/L. The EU’s requirement for boron content in toys made of liquid, pigment, jelly and other materials is limited to 300mg/kg. The Defective Product Management Center of the General Administration of Market Supervision has tested 10 kinds of finished crystal mud products randomly purchased, and found that the boron content of 8 kinds of products exceeded 300mg/kg, and the highest one reached 1336mg/kg, far exceeding the safety limit of boron content in various countries. Once children eat by mistake when blowing bubbles with these crystal mud, there may be a danger of borax poisoning.

　　Perhaps it is realized that this toy with borax directly added is easy to be found, and some merchants have introduced the so-called "non-toxic crystal mud" products, adding some daily chemical products to the glue containing polyvinyl alcohol instead of borax, such as washing powder, laundry detergent, shower gel, guar gum and so on. "This is actually very confusing, because these daily chemical products actually contain borax ingredients, and children also have the safety hazard of eating poisoning during playing." The Defective Product Management Center of the General Administration of Market Supervision pointed out in the consumption tips that any toy containing borax does not meet the requirements of our country.

　　The Defective Product Management Center of the General Administration of Market Supervision also specially reminded that homemade "mud" toys are more dangerous than finished products, and children will be directly exposed to large doses of borax and other chemical ingredients during play. Skin exposure to these chemicals for a long time is likely to cause chemical burns, allergies or cumulative poisoning; If children abuse the preparation container during play, such as drinking water from a glass filled with borax, or not washing their hands in time after play, it is easy to eat borax or other chemical ingredients by mistake, leading to the danger of poisoning.

　　For toys such as crystal mud, especially homemade "mud" toys, the advice given by the Defective Product Management Center of the General Administration of Market Supervision is: Don’t buy!

　　Online celebrity balloons will glow or explode.

　　On this summer night, you can often see sparkling balloons with colorful light in squares or parks, which are very popular with children. This kind of balloon first attracted attention on online social media, and was called online celebrity balloon by many people. However, although the online celebrity balloon is beautiful, it has hidden dangers. According to media reports, there was a balloon explosion in online celebrity somewhere in Jiangsu province, and four people were hospitalized with different degrees of burns.

　　How can a balloon explode? How serious is the harm?

　　According to the Defective Product Management Center of the General Administration of Market Supervision, this luminous balloon is mainly composed of transparent balloons, multicolored light strips and battery boxes, and its structure is very simple. A string of thin multicolored LED strip is wrapped around the surface of the transparent balloon, and a small battery box is tied to the tail end of the traction rope. The battery is placed in a plastic box, and the power supply is directly connected to the light strip, and the light can be emitted when the switch is turned on.

　　The balloon itself is a pressure vessel, and with this design and construction, the safety risk is higher. Testing by the Defective Product Management Center of the General Administration of Market Supervision found that balloons in online celebrity are mostly made of plastic, and once they come into contact with high-temperature heat sources (such as stoves) or open flames (such as lighters), balloons may explode. On the one hand, the surface temperature of the melted plastic is very high at high temperature, and the plastic liquid dripped from the melted plastic will cause serious burns and scalds if it sticks to human skin. On the other hand, balloon deflagration will produce irritating toxic gas, which may cause burns and other injuries to human respiratory tract. In addition, due to the bare wires, sparks may be generated during use, which may cause the balloon to explode.

　　Some experts pointed out that the gas inside the online celebrity balloon may also become a safety hazard. For safety reasons, balloons are generally filled with inert gases such as helium, and hydrogen has long been prohibited from being used to inflate balloons because of its flammability and explosiveness. However, because hydrogen is cheaper than helium, some unscrupulous merchants may still use hydrogen to inflate online celebrity balloons. In a online celebrity balloon explosion reported by the media, experts pointed out after analysis that "judging from the power of the balloon explosion described by the injured, the balloon they bought is likely to pass off hydrogen as helium".

　　The Defective Product Management Center of the General Administration of Market Supervision reminds that children should play such balloons under the care of their parents; Stay away from fire sources, heat sources and sharp objects when playing with balloons, and don’t use lighters to burn the traction line of balloons; It is best not to buy such balloons when the weather is very hot, because high temperature weather is more likely to cause balloon explosion; Don’t take a balloon in a car, subway, elevator, etc. Once an explosion occurs, the impact of a closed space will be very great.

　　Laser pen can cause permanent damage to eyes. Don’t play with children.

　　The light is dazzling and dangerous. Online celebrity balloon, laser pointer.

　　I don’t know when, the laser pointer used as an indicator in classroom teaching, conference explanation and other places has become a toy for many children and a dangerous toy. As a result, there have been many reports in the media: "When a laser pointer shines, the eyes of a 7-year-old boy can’t see", "When an 8-year-old boy plays with a laser pointer, his eyes are permanently damaged", and "The sampling tests of online shopping for children’s laser pens all exceed the standard, and the harmful visual damage is irreversible" … … According to the Defective Product Management Center of the General Administration of Market Supervision, according to the product injury monitoring and network public opinion monitoring, injury accidents involving laser pens have occurred frequently in recent years.

　　Laser pointer, also called laser pointer, is a portable device that uses battery and laser module (light emitting diode) to emit visible light beam, which is mainly used to accurately indicate the target at a long distance. In China, according to the degree of radiation hazard from low to high, laser products are divided into the following grades: class 1, class 1M, class 2, class 2M, class 3R, class 3B and class 4. The Defective Product Management Center of the General Administration of Market Supervision pointed out that if laser products are not used properly, it will cause serious damage to human body, especially for products of 3R and above. Laser pens sold on the Internet usually have very high power and can even light matches, cigarettes, clothes and so on.

　　The power is so high that it can ignite clothes. If you irradiate your eyes, the consequences can be imagined. According to experts, due to the characteristics of eye imaging, when the laser passes through the eye, it will be focused on a very small point on the retina, which will lead to an instantaneous increase in temperature and destroy the photosensitive cells of the retina. If the laser energy is strong enough, it will cause permanent damage without causing blink reflex (usually less than 1 second). It should be noted that low-power laser may also cause harm to eyes, and some high-intensity lasers still do great harm to eyes even after scattering from the surface of objects. Children in the developmental stage have delicate eye tissues and thin retinas, which are more vulnerable to injury.

　　Laser pointer will not only cause direct damage to eyes, but also interfere with normal vision, which may lead to other accidents. For example, illuminating vehicles, airplanes, etc. with a laser pen may affect the normal vision of drivers and pilots and cause serious accidents.

　　Of course, the laser pen is not unusable, but should be used scientifically and safely. According to different use occasions and users, the laser pen with corresponding radiation level should be carefully selected. The Defective Product Management Center of the General Administration of Market Supervision reminds that laser pen products can be used in situations such as classroom teaching and conference explanation. The laser in children’s toys should meet the requirements of Class 1 laser radiation power limit.

　　"The laser pens sold as toys in the market are mostly higher than this limit, which has great security risks and cannot be bought and played for children." The defective product management center of the General Administration of Market Supervision stressed.

IT House reported on April 18th that Lei Jun, the founder and chairman of Xiaomi, started broadcasting at Xiaomi Auto Delivery Center today, and "talked with netizens about the sale of Xiaomi SU7 these days".

Lei Jun gave a more specific timetable when answering the netizen’s question "When will the wireless CarPlay function of Xiaomi SU7 go online": it is expected to get on the bus through OTA in early May.

Lei Jun asked the team to push OTA upgrade at least once a month, and planned to open NOA in 10 regions to users at the end of May and push NOA to the whole country in August.

Lei Jun also revealed that the current model plan of Xiaomi Automobile belongs to the confidential stage, and there is no plan to make an off-road vehicle. When talking about this topic, Lei Jun said that the Great Wall brand off-road vehicles have done a good job.

In addition, Lei Jun believes that if Xiaomi SU7 fails, it will definitely be caused by three reasons: cognitive error, inertia thinking and idol burden.

According to the previous report of IT House, Xiaomi Auto’s iPad car control function has been launched. Just go to the Apple App Store to search and download the "Xiaomi Auto Expansion Screen" app, and after connecting the car hotspots, you can enjoy the seat air conditioning adjustment, multimedia adjustment, audio-visual entertainment and other native car-like experiences. Lei Jun once said that Apple users also have a good experience in driving Xiaomi cars, and Xiaomi smart cockpit is compatible with Apple wireless AirPlay and Carplay.

It is a great challenge for the idol Chen Youwei to participate in Actor in Place. In previous programs, from YeHua in to the sky kingdom to King Guo in Empresses in the Palace, Chen Youwei was criticized by the director, but the latest program ushered in a reversal.

Successfully joined the crew directed by Chen Kaige, and Chen Youwei played "Pass the Customs" with Ren Min and Dong Siyi. In this clip, Ren Min and Chen Youwei were actually two smugglers with goods under the cover of students.

Although "Pass the Customs" is not long, it contains a lot of information. Teenagers’ rebellion, young people’s love entanglements, and teenagers’ reckless bravery are all presented in this clip.

After the performance of "Pass the Customs", it was well recognized by the director and the audience, especially the picture of Chen Youwei running, which was very emotional. Therefore, after the latest issue of "Actors in Place" was broadcast, many viewers also said that Chen Youwei really chose the right role this time.

Not only that, Tung shing Yee also bluntly said in the program that the positioning of the three actors in the whole "Pass" is very accurate, and the harmony of the whole segment is the main reason why "Pass" successfully attracts the audience’s attention.

After the review, Tung shing Yee suggested that Chen Youwei should hug the two actresses around him. This time, Chen Youwei also had no idol burden at all, and gave Ren Min and Dong Siyi a "straight man" hug.

Indeed, in the process of an actor’s acting, a good "play partner" is still very important. Undoubtedly, Ren Min, born in 1999, is a young actress. Her performance this time is not only to let the audience see her own brilliance, but also to be more rare, her own light is dazzling, but it will not hide the brilliance of her opponent’s actors. This is really not easy.

In the first episode of "Actor in Place", Ren Min’s partner Shi Baiyu starred in Better Days’s segment, and Ren Min’s acting skills were also quite recognized. Her market was initially rated as S-class. After Better Days’s performance, she still got the S card, and even watched Better Days’s segment. It was an intuitive feeling that, to some extent, Ren Min was driving Shi Baiyu’s emotions. In the end, Ren Min and Shi Baiyu were also a win-win situation, and both of them kept up.

The same is true of this "Pass", and Chen Youwei’s progress is obvious to all. When Chen Youwei plays with other young actors, the effect is that Chen Youwei is dragging down his teammates. But this time, in Pass, Ren Min, Dong Siyi and Chen Youwei all perform their own personalities, and they complement each other, which finally makes the whole picture very amazing.

As a young actor, although Ren Min’s face value is very "idol", from Yi Yao in the movie "A River of Sorrow" to Princess Hui Rou in the TV series "Qingpingle", the role played by Ren Min is not a simple idol. Perhaps it is the positioning when she debuted that she has never played a silly idol drama. Therefore, Ren Min’s acting skills are not flattering and will not make the audience feel that she is using her face value to make up for her acting skills.

However, it is precisely because idol dramas are rarely performed that Ren Min’s popularity in the entertainment circle is not very high. Even compared with Chen Youwei, her popularity is slightly inferior. This time, it is also a good thing for Ren Min to participate in the program "Actor in Place". Because of the popularity of the program itself, the popularity of the actors has also increased and attracted more attention. In the program, some producers bluntly said that Ren Min is very aura.

A good film and television drama actually needs the actors to fulfill each other, and a popular variety show actually needs to be "mashed up" to attract the audience’s attention. A good play partner like Ren Min, coupled with Chen Youwei’s controversial points, and their mix and match combination, finally presents a good screen effect.

In this kind of competitive performance program, the actors can collide with each other and eventually the audience will buy it. For example, in previous programs, Yan Zidong and Caiqi Yang performed "The Kiss of Pranks". At that time, when it was broadcast, both the director and the audience felt that the performance was very real and the effect presented was very comfortable.

In "Pass the Customs", Ren Min relies on acting skills, Chen Youwei relies on the advantages of facial features and movements, and Dong Siyi relies on the simple temperament of the girl next door. The highlights of each other are integrated without conflict, which makes a relatively successful work. Whether it is Chen Youwei, Dong Siyi or Ren Min, they can present such a work, which is also a kind of mutual fulfillment for three people. Text/Chen Wei is cool
