[Text/Observer NetworkBlocking open source】 According to the bidding contract signed by the Russian Saturn engine company this year published by the Russian government affairs open website, the company signed two contracts with the Equipment Department of People’s Republic of China (PRC) Military Commission, including a total of 224 D-30KP2 engines, which are scheduled to be delivered before 2020. The contract indicates that the total price of these two contracts is about 657 million US dollars according to the 2010 US dollar exchange rate, with an average price of 3 million US dollars per engine.

Signing a contract with Russia indicates that Yun -20 will enter the stage of mass production.

Screenshots of two contracts posted on the Russian government affairs website.

According to this, it is speculated that most of these engines will be used for the production of Yun -20 strategic transport aircraft and H -6K strategic bomber, in addition to supporting the maintenance of the previously purchased Il -7678 series fleet. According to the Russian network transmission, if the 170 engines in the contract are used for new aircraft, it can at least meet the requirements of manufacturing 40 Yun-20s.

According to the contents of the contract, the Sino-Russian D-30KP2 engine contract was signed in two parts, one of which was 54 engines with a price of 158 million US dollars. According to regulations, 10 units will be delivered in 2017; 12 units delivered in 2018; 12 sets in 2019; 20 in 2020.

The other part is 170 engines at a price of 499 million US dollars. According to regulations, 44 units will be delivered in 2017; 40 sets in 2018; 48 units in 2019; 38 in 2020.

It is reported that China and Russia signed two contracts to purchase D-30KP2 engines in 2009 and 2011, including 55 in 2009 and 184 in 2011. The engines stipulated in the above two contracts shall be delivered before the end of 2015.

At present, China Air Force uses D-30KP2 engines, including Il -76 transport aircraft, Il -78 tanker, H -6K strategic bomber and Yun -20 large transport aircraft newly delivered to the Air Force.

China Air Force acquired more than ten Il-76s from Russia in 1990s. After entering the 21st century, it was once planned to purchase 38 additional Il -76 and Il -78 aircraft from Russia, but because the Russian side could not deliver them, it was finally compensated by D-30KP2 engines. After 2010, China successively obtained about 10 second-hand Il-76s from Russian, Ukrainian and other countries, and continued to serve after renovation and modification.

Using these D-30KP2 engines, China has produced nearly 60 H -6K strategic bombers and equipped its troops, which also met the requirements of the test flight and initial production of Yun -20.

Zhuhai Air Show will show an improved model of Yun -20F-100 transport aircraft with domestic turbofan engine. The fuselage of the aircraft is lengthened and the engine is replaced with domestic turbofan engine.

It is normal for the special aircraft of large transport aircraft to change the engine many times in its life. The picture shows the KC-135E tanker of the US Air Force, which changed the engine model for the first time in the 1980s, from the earliest J57 turbojet engine to TF33 turbofan engine.

In the 21st century, about 136 KC-135 tankers have been replaced by CFM-56 engines, which have doubled the thrust and increased the range by 60% compared with the original J57 engine. Before the new generation KC-46 tankers came into service, they became the best performance tankers of the US Air Force.

At present, in addition to changing the models of engine test platform, aerial tanker and early warning aircraft, the number of Il -76 aircraft undertaking air transport tasks is about 24, which is equivalent to a transport aviation regiment (not fully staffed), and it is far from meeting the demand of China Air Force for strategic delivery capability.

According to the agreement signed with Russia this time, the purchased engines will obviously be used for mass production of new transport aircraft in addition to replacing the engines that have been purchased on the aircraft and need to be replaced. If, as the Russian media said, the first contract of 54 units is mainly used to meet the maintenance of the previously purchased Il -76 and Il -78 fleets, then the remaining 170 engines can meet the requirements of producing 42 Yun -20 aircraft.

Russian D-30KP2 engine

If this goal is achieved, China Air Force’s strategic transport fleet will be completely updated to Yun -20, while the current Il -76 can be changed to Il -78 aerial tanker, making up for the major shortcomings of China Air Force’s lack of tankers at present.

At the same time, a number of Yun -20 aircraft can be changed into airborne early warning aircraft platforms to enhance the strength of China’s early warning aircraft fleet.

　　Sina Auto News On the evening of July 11, 2019, a new generation of Song Pro models of BYD’s new energy dynasty family went on the market. The new car was built based on the new BNA architecture. The appearance and interior design adopted the latest Longyan 2.0 design language of BYD family, and the power part provided three power forms: gasoline /DM dual-mode hybrid/pure electric. A total of 12 models have been launched in the new car, and the price range of the whole car system is 898-219800 yuan.

　　1, BYD Dragon Face 2.0 design language, 12.8-inch rotating screen.

　　2. LED light group, DiLink2.0 intelligent network connection system and intelligent driving assistance technology.

　　3. Gasoline /DM dual-mode hybrid/pure electric rich power system

　　In terms of appearance, Song Pro adopts the design language of BYD Dragon Face 2.0, and the front face is more recognizable. The headlight department adopts full LED light group, which has the effect of lighting step by step and turning signal flow. The daytime running light adopts dragon claw elements, which also makes the headlights more recognizable.

　　According to different models, the front face design of Song Pro fuel /DM/EV models is different. The five transverse decorative strips inside the front grille of the fuel version adopt a single-layer design, and the opening area is also larger. The fog lamp style is also different from that of the electric version. On the other hand, the five grille trims of DM model have become double-layer design, and the trims on both sides of the lower enclosure have become C-shaped, and the opening area has been reduced; The grille of EV model is replaced with a closed design consisting of short chrome-plated line array decorative strips. This should be the main way to distinguish the three kinds of motivation.

　　The side of the car body has a suspended roof design, and the fender lines that are picked up at the front and rear also make the car more dynamic. The external dimensions of the Pro family in Song Dynasty are the same, with the length, width and height of 4650/1860/1700mm and the wheelbase of 2712mm respectively. The more eye-catching design for the rear of the car is the through LED taillight group. The difference between the three power models mainly lies in the tail logo.

　　The interior of Song Pro EV is also equipped with a 12.8-inch adaptive rotating suspension Pad, with a built-in DiLink2.0 intelligent network connection system, which provides basic functions such as navigation, cloud music, online broadcasting, etc. It is also compatible with more than 4 million App applications and has OTA air upgrade function.

　　In addition, Song Pro’s new energy vehicle is equipped with the unique L2 Plus intelligent driving assistance technology at the same level, including ACC-S&G stop-and-go full-speed adaptive cruise system, LDWS lane departure warning system, BSD blind spot monitoring system and other common L2 functions, as well as "black technology" such as holographic transparent image system and cloud service APP intelligent remote driving.

　　Song Pro DM offers two power models. Among them, the four-wheel drive performance version is equipped with a plug-in hybrid system consisting of a 1.5T direct injection engine and a rear axle single motor. The comprehensive maximum power of the system is 323 HP, the peak torque is 525 Nm, it is matched with a 6-speed dual-clutch gearbox, and the 0-100km/h acceleration time is 6.5 seconds. Song Pro DM four-wheel drive high-energy version added a front axle motor with a maximum power of 150 HP to form a "three-engine four-wheel drive" hybrid system, with a comprehensive maximum power of 473 HP and a peak torque of 775 Nm, which also matched the 6-speed dual-clutch gearbox, and the official acceleration time of 0-100km/h was shortened to 4.7 seconds.

　　Song Pro EV offers two power models. The high-power version and the high-power and long-life version are both equipped with a front-axle AC permanent magnet synchronous motor, with maximum power of 163 HP and 184 HP respectively and peak torque of 280 Nm. At the same time, they are equipped with battery packs with capacity of 59.1kWh and 71kWh respectively, corresponding to NEDC cruising range of 405km and 502km respectively, and their 0-50km/h acceleration time is 4.3 seconds. In terms of charging time, it takes 1 hour and 1.2 hours to fully charge the power in the high-power charging pile fast charging mode, while it takes only half an hour to quickly charge the power from 30% to 80%.

　　In terms of competing products, in fact, there are still many opponents involved in BYD’s Song Pro model, because the power system of Song Pro includes fuel, hybrid and pure electric, so the pressure of Song Pro is still quite great, but BYD has always been on a cost-effective route. Although independent brands often use the same routine, from the perspective of Song Pro’s configuration and comprehensive performance, it is still very strong in the same class, aiming at the demand of Chinese people for cars. Song Pro has certain advantages in space, maintenance costs, configuration richness and power level. If price concessions are added, the sales of Song Pro should still perform well.

　　Thanks to the development of new energy in recent two years, BYD’s brand awareness has been greatly improved, especially the performance made by Qin and Tang, which has been recognized by more and more consumers. Song Pro took the opportunity to appear, continuing the cool dragon face design, large-size optional screen in central control, and superior DM performance. In fact, these three points alone can get rid of competitors in the market. Although the new energy policy has been recycled, I think manufacturers can still attract consumers to buy it through their own subsidies.

CCTV News:April 8th is the International Day for the Protection of Rare Animals. We walked into Jiangcheng County, Pu ‘er, Yunnan Province, one of the habitats of Asian elephants, to see the activities of local Asian elephants.

Early in the morning, the reporter followed the Asian elephant monitoring team to the Manlao River in Dashujiao Village, Kangping Town, Jiangcheng County. According to the staff, there were 42 wild Asian elephants in this area recently.

In view of the shortage of food for elephants in winter, corn, sugar cane, bananas, etc. are specially planted in some specific areas for elephants to eat. These places are also called "elephant canteens". However, at this time, corn and sugarcane have just entered the cultivation period, and there is relatively little food in the wild, which leads to more frequent activities of elephants entering the village and is prone to injury accidents. Therefore, the local people deliberately artificially feed at the entrance of some villages.

In addition to feeding the Asian elephants well, the daily focus of the staff is to monitor the range of activities of the Asian elephants.After locating the elephant activity area, the staff immediately controlled the roads along the way and placed warning signs. At the same time, they issued early warnings through WeChat group, monitoring and early warning platform and village broadcasting, and tracked the monitoring activities with drones.

Yunnan Shuangbai: Photographers shot a lot of rare green peacock videos.

Green peacock is a national first-class protected wild animal, mainly distributed in Yunnan Province and some Southeast Asian countries. At present, the number in China is only between 550 and 600. Green peacocks are timid and difficult to approach, so there are few related videos except a few pictures taken by infrared cameras. Recently, photographers have been crouching for 6 days, shooting a large number of green peacock videos with a 360-degree panorama camera.

In the picture, these green peacocks are foraging by the river bed. It’s the breeding season of green peacocks. During the period of crouching, the photographer photographed that these green peacocks sometimes play, sometimes take a sand bath in the river valley, and sometimes unfold a long tail screen.

Gu Bojian, a teacher at the School of Ecological Environment of Ningxia University: "There are both adult birds and adult birds in the picture. The male green peacock of an adult bird has a shorter tail screen than that of an adult bird. This season is the breeding season for green peacocks. The males have long tail screens, and the feathers in other parts of their bodies are also the most glamorous. Green peacocks can get rid of parasites and keep their feathers bright through sand bath. "

According to experts, this group of green peacocks in front of us was photographed by the infrared camera of the Management and Protection Bureau of Dinosaur River State Nature Reserve in May last year. At that time, they were still chicks with gray-black feathers. After nearly a year, these green peacocks have grown bright feathers and long tail screens.

Wang Sibeng, Director of the Management and Protection Bureau of Dinosaur River State Nature Reserve in Shuangbai County: "As the only original peacock population in China, there are about 550— 600, all distributed in Yunnan Province. According to the monitoring data of the nature reserve, there are about 360 native green peacocks in Shuangbai County, accounting for more than half of the national population. "

　　In 2022, the No.1 Document of the Central Committee pointed out that we should vigorously promote the construction of digital villages, promote the development of smart agriculture, and promote the integrated application of information technology and agricultural machinery and agronomy. The "14th Five-Year Plan" and the outline of the long-term goal in 2035 proposed to build smart agriculture and accelerate the modernization of agriculture and rural areas. An agricultural intelligent revolution with intelligent agriculture as its manifestation has arrived. In this issue, relevant experts are invited to discuss the issue of smart agriculture.

　　Moderator: Xu Xiangmei, director and researcher of the Theory Department of Economic Daily.

　　Deep integration of information technology and modern agriculture

　　Moderator: What are the distinctive features of smart agriculture that are different from traditional agriculture? Why should we attach great importance to smart agriculture?

　　Li Daoliang (Director, National Digital Fisheries Innovation Center, China Agricultural University): Smart agriculture is the product of deep integration of new generation information technologies such as Internet of Things, cloud computing, big data, spatial information technology, blockchain and artificial intelligence, modern agricultural planting and breeding technology, and the industrial chain of agricultural products processing, circulation, trading and consumption. It is the "ecological integration" and "gene recombination" of modern information technology and the whole industrial chain of agricultural production, operation, management and service.

　　The main features of smart agriculture are as follows.

　　First, agricultural production factors are digitized, networked and online. Using advanced sensing, remote sensing and machine vision, the information of agricultural planting and breeding environment, the growth information of planting or breeding objects, and the working condition information of production machinery and equipment can be digitally marked and obtained. Using Internet, 5G, narrowband Internet of Things, satellite communication and other network communication technologies, remote digital information scheduling is realized.

　　Second, the regulation and decision-making of agricultural production process is cloud-based and intelligent. Based on the massive data of the production process, we make full use of big data and artificial intelligence technology, and process the data with the help of agricultural cloud computing platform to generate the optimal growth regulation model of agricultural animals and plants, so as to realize the intelligent regulation of the whole production process.

　　The third is the synergy of the whole link, whole process and whole chain of agriculture. Through the agricultural cloud computing platform, the distributed agricultural production system, logistics system, trading system and consumption system are connected into an organic whole, so that agricultural production, operation, management and consumption can be optimized in coordination with the main work.

　　The fourth is the credit and safety of agricultural management. All the data of agricultural production, circulation, transaction and consumption are uploaded and stored in the blockchain shared distributed database through the blockchain decentralization technology, forming an unbreakable account book that can be consulted by consumers and buyers, making agricultural management credit and safe.

　　The significance and function of developing intelligent agriculture are mainly reflected in the following aspects.

　　Promote the conservation and efficient utilization of resources and the green development of agricultural science. Through the Internet of Things, big data, artificial intelligence, robots, intelligent equipment and other technologies and breeding techniques, planting and breeding operations can get rid of the natural environment and human dependence, and build an agricultural production automation system that integrates environmental physiological monitoring, crop model analysis and precise adjustment, so as to improve labor production efficiency, land output rate and resource utilization rate. Through digital measurement and control, we can meet the needs of crop growth, ensure resource conservation and avoid environmental pollution, and realize the green development of agriculture. At present, agricultural developed countries have realized that one person cultivates 5,000 mu of land, one person produces 500 tons of vegetables annually, one person grows 1 million potted flowers, one person raises 200,000 chickens and produces 180,000 eggs a day, and one person raises 10,000 pigs, 200 cows and 100 tons of fish, completely changing the problems faced by traditional agriculture with extensive management, weak competitiveness and low resource utilization rate.

　　Promote agricultural standardized production and ensure "green and safety on the tip of the tongue". Real-time dynamic monitoring of soil, atmospheric environment and water environment through digital, networked and intelligent equipment to make it meet the environmental standards of agricultural production; All aspects of production can also be produced by intelligent equipment according to certain technical and economic standards and specifications; Through digital and intelligent equipment, the quality of agricultural products is accurately detected in real time to ensure that the final agricultural products meet the corresponding quality standards. With the help of Internet, QR code, radio frequency tag, blockchain and other technologies, we will establish an information platform for agricultural product quality and food safety that can be traced and shared in the whole process, improve the supervision system of agricultural product quality and safety process from farmland to table, and ensure the people’s "green and safety on the tip of their tongue".

　　Promote the integration and branding of agricultural management. The application of information technology has broken the space-time geographical limitation of agricultural market, and the data of agricultural materials procurement and agricultural products circulation will be monitored and transmitted in real time, effectively solving the problem of information asymmetry. Use the e-commerce platform to expand the sales channels of agricultural products, build an integrated agricultural product management system through self-operated bases, self-built websites and independent distribution, and promote the market marketing and brand operation of agricultural products.

　　Promote the integration of primary, secondary and tertiary industries. The digitalization, networking and platformization of agriculture will guide the development and alliance of new agricultural business entities such as large professional households, family farms, farmers’ professional cooperatives and excellent enterprises, promote the close connection of related industries such as agricultural product production, circulation, processing, storage and transportation, sales and service, realize the effective allocation of agricultural factor resources, and make the industry and factor agglomeration change from quantitative collection to qualitative change, so as to rebuild the whole agricultural industrial chain and realize the cross-infiltration and integrated development of agriculture and secondary and tertiary industries.

　　Intelligent management aims at system optimization.

　　Moderator: What is the development status of smart agriculture in developed countries? What experience does it have in the research, development and application of new smart agriculture technologies that are worth learning from in China?

　　He Yong (Director, Digital Agriculture and Rural Research Center, Zhejiang University): The United States is a typical modern agricultural country in the world, with about 3.5 million people directly engaged in agricultural production, which not only feeds 300 million Americans, but also becomes the largest exporter of agricultural products in the world. Full mechanization and rapid development of digital technology have laid a solid foundation for the development of its smart agriculture. At present, the United States has formed a sophisticated and large-scale intelligent agricultural production system. 69.6% of farms use sensors to collect data, and agricultural robots are used in agricultural production such as sowing, spraying and harvesting.

　　As the world’s largest agricultural drone spraying country, Japan mainly uses the agricultural Internet of Things as the information source, applies a large number of agricultural robots, and constantly pursues labor-saving and refined agricultural production to solve the problem of agricultural labor shortage.

　　The characteristics of smart agriculture in Europe, America, Japan and other developed countries are based on the development trend of modern agriculture, combined with the actual agricultural production in their own countries to carry out theoretical and practical research on smart agriculture. With the support of modern information technology, we should give full play to the role of smart agricultural equipment, and apply technologies such as Internet of Things, artificial intelligence, big data and 5G to consider crops, soil, environment, meteorology, equipment and personnel as a whole system, so as to realize intelligent management with the goal of overall optimization of the system.

　　Developed countries have the following experiences in the research, development and application of smart agricultural technology, which are worth learning from in China.

　　First, starting with improving productivity and solving the bottleneck problem of agricultural production. The Netherlands, Israel and other countries are seriously short of fresh water resources, so they vigorously develop facility agriculture, implement soilless culture and fine spray and drip irrigation systems. Japan’s agricultural labor force is aging and seriously inadequate, and it vigorously develops agricultural drones and agricultural robots, greatly improving operational efficiency. South China is also facing the shortage of labor force and the availability of agricultural inorganic materials in hilly and mountainous areas. We should develop multifunctional small-scale operation equipment, realize the substitution of machines and solve the problem of mechanized operation in hilly and mountainous areas. The main grain producing areas should implement full mechanization to improve labor productivity. Economically developed areas can study the establishment of unmanned or few farms, orchards, pastures, fishing grounds, etc., to improve the level of agricultural modernization.

　　Second, the implementation of standardized planning and operation is the basis and condition for the development of smart agriculture. Standardized planning and refined management of farmland, orchards and pastures in developed countries have created conditions for large-scale and efficient use of intelligent agricultural equipment, greatly improving operation efficiency, yield and quality. China’s farmland, orchards and pastures need to promote standardized planning as soon as possible, formulate standardized operation specifications, and develop high-efficiency supporting equipment to create conditions for large-scale mechanized operations.

　　Third, make full use of modern science and technology to plug in the wings of science and technology for agriculture. A large number of foreign countries use aerospace technology and meteorological data to achieve rapid and accurate acquisition and intelligent management of farmland information. With the development of Internet of Things, big data and 5G technology, especially the application of high-resolution satellite and Beidou positioning system, it is expected to realize real-time dynamic acquisition of crop and animal and plant growth information, and dynamically adjust and control temperature, humidity and illumination according to crop growth requirements, and accurately spray fertilizers and fertilizers.

　　The development of smart agriculture in various places has achieved practical results.

　　Moderator: What is the development status of smart agriculture in China? What are the successful experiences and innovative explorations of smart agriculture development in various places?

　　Kang Chunpeng (Associate Research Fellow, Information Center, Ministry of Agriculture and Rural Affairs): China’s agricultural and rural informatization development level is still in the primary stage, but the agricultural industry is accelerating its transformation towards digitalization, networking and intelligence, and the consumer Internet continues to extend and expand to the industrial Internet. According to the monitoring of the Information Center of the Ministry of Agriculture and Rural Affairs, in 2020, the informatization level of agricultural production in China will be 22.5%, including 18.5% for field cultivation, 23.5% for facility cultivation, 30.2% for livestock breeding and 15.7% for aquaculture. In recent years, China’s smart agriculture has gradually achieved results, and the level of intelligence and unmanned has gradually improved, showing the following highlights.

　　First, new products and technologies are booming. Modern information technology is widely used in all aspects and fields of agricultural production, and new products, technologies and models emerge one after another. The digital transformation of agriculture has been accelerated, and the traditional agriculture has been transformed into intelligence. Intelligent identification systems for crop moisture, seedling condition, diseases and pests and disaster monitoring in the field and intelligent robots for farming and harvesting have been continuously developed. In particular, products such as automatic harvesting equipment, agricultural sensors, camera monitoring, pest monitoring and early warning have been widely used.

　　Second, no one or few farms broke ground. The rural network infrastructure has been continuously consolidated, especially the maturity and popularization of big data, 5G and artificial intelligence technologies, which provide basic conditions for the development of unmanned or few farms. In Changsha, Hunan, Wuhu, Anhui, Sanjiang, Huzhou, Zhejiang, Chongzhou, Sichuan, Foshan, Guangdong and other places, no one or few farms broke ground, and all farm production operations were completed through remote control of facilities, equipment, machinery and so on, automatic control of the whole process or autonomous control of robots.

　　Third, the construction of big data has achieved initial results. From the national level, the sharing of government data resources and the integration of information systems have achieved phased results, the national integrated government service platform has been basically completed, and the pattern of co-construction and sharing of government data resources has basically taken shape. From the perspective of local practice, Anhui, Zhejiang, Jiangsu, Guangxi and other places have actively promoted the construction of big data in agriculture and rural areas, and successively built big data platforms. Zhejiang is vigorously promoting the digital reform of "agriculture, rural areas and farmers" throughout the province.

　　Fourth, market players have become a new force. Market players are becoming an important force in building smart agriculture. Large enterprises have entered the field of smart agriculture. The three major telecom operators and Internet companies such as Huawei, Alibaba and Tencent have laid out smart agriculture. Sinochem, Zoomlion and Country Garden have begun to enter smart farms. In addition, agricultural enterprises also take the initiative in the digital transformation. Traditional agricultural enterprises such as COFCO, Beidahuang, New Hope and Haisheng Fruit Industry vigorously develop smart planting, smart animal husbandry, smart fisheries and smart processing.

　　Since 2019, Zhejiang has taken the lead in building a "digital agricultural factory" in the country, and carried out systematic integration and comprehensive application of digital technology and equipment around the production environment, production process, quality and safety, circulation marketing and technical services. After several years of practice, in 2021, guidelines for the construction of digital agricultural factories, digital fishing grounds and pig farms were successively issued. Shui Mu Vegetable Factory in Deqing County integrates advanced technology into production management, product marketing, quality control, ecological protection and other links, achieving an annual output of 2 million kilograms of tomatoes, with an efficiency of 30 times that of traditional fields; Tongxiang Huateng Animal Husbandry uses technologies such as Internet of Things, artificial intelligence, bio-ear tags and blockchain to promote the digital transformation of animal husbandry and create a safer, more productive and fully automatic breeding environment, saving 80% labor and 60% water.

　　Zibo, Shandong Province took the lead in building a digital agricultural rural central city in China, focusing on five key tasks: agricultural production and processing, agricultural product warehousing and logistics, agricultural product marketing, integrated development of agriculture and tourism, and consolidating grassroots foundation, and building a smart sharing "cloud brain", an efficient and high-quality "cloud industry", a regional center "cloud market", a convenient and inclusive "cloud finance" and a new service "cloud village". In 2021, 4.54 billion yuan of major special funds for rural revitalization will be set up, and 40 key digital agriculture and rural projects will have an investment of 5.186 billion yuan, and 30 typical application scenarios and 10 smart towns will be built.

　　From a practical point of view, the development of smart agriculture in many places has achieved remarkable results and formed experience for reference. First of all, give full play to the role of market players, establish an effective market in full accordance with the laws of economic operation and information development, and stimulate the vitality of various market players. Secondly, we should play the role of a promising government, guide market expectations with policies, clarify the investment direction with planning, incite social capital with finance, and regulate market behavior with the rule of law. Finally, do a good job in pilot demonstration. Smart agriculture is an advanced form of agricultural informatization, which involves relatively advanced technology and has great market risks. On the basis of fully respecting farmers’ dominant position, we should show them, lead them to work and earn money, and inspire them to use modern information technology to develop production and improve their lives.　

　　Now, who hasn’t received several harassing calls for sales promotion? Who doesn’t have several apps installed in their mobile phones? Is there a connection between the two? Maybe there is.

　　From July 17 to August 13, 2018, China Consumers Association organized a questionnaire survey on "Personal Information Disclosure of APP". According to Pi Xiaolin, director of the commodity service supervision department of China Consumers Association, 85.2% of the 5,458 valid questionnaires collected said that they had experienced personal information disclosure of APP, and only 14.8% had not experienced personal information disclosure. Nearly 90% of the respondents who suffered information leakage said that they had been harassed by sales calls or text messages.

　　Nearly 90% of mobile apps require location information.

　　According to the Regulations on the Management of Mobile Internet Application Information Services promulgated in 2016, APP operators should follow the principles of legality, justness and necessity in collecting and using users’ personal information, clearly state the purpose, method and scope of collecting and using information, and obtain the consent of users. However, in actual operation, APP operators basically require user information to be "undefended" according to their own wishes.

　　The survey results show that the right to read location information and the right to access contacts are the most common situations when installing and using mobile apps, accounting for 86.8% and 62.3% respectively. A relatively high proportion of respondents were asked to read the call records (47.5%), read the short message records (39.3%), turn on the camera (39.3%) and record the microphone (24.6%).

　　The reporter looked at the APP downloaded from his mobile phone and found that he had the most permission to use the location service. Among them, Beijing Mobile, Rookie Wrap, Public Comment, Didi Chuxing and other apps require location permission, which is a service necessity. However, video apps such as iQiyi and LeTV, dragonfly FM audio software, photo apps without other cameras and butter cameras, kitchen menu software, Baidu input method, WPS text editing software, etc., seem to have little to do with the user’s location, but they also require location permission, which does not conform to the necessary principle.

　　The "whatever you want" of APP has aroused the vigilance of many consumers. According to the report, it is more serious for mobile apps to obtain users’ privacy rights when their own functions are unnecessary, and 67.2% of the respondents said that they had encountered this situation.

　　Personal information is mostly collected for promotional advertisements.

　　Although most operators claim that they ask for more rights in order to better provide services to users, this is not consistent with users’ feelings.

　　According to the survey results, 77% of the respondents believe that promoting advertisements is the main reason why mobile apps collect personal information. Especially after obtaining the location information, the advertisement can be pushed more accurately. 45.9% of the respondents believe that operators are selling and exchanging personal information, and 24.6% of the respondents believe that they are engaged in fraud and theft.

　　The user’s feelings come from personal experiences in life. Ms. Zhang, a loyal user of today’s headlines, told reporters that when she used today’s headlines, she found that the headlines changed local channels at any time on the page according to the different cities where she lived, and also pushed local news and local advertisements to her.

　　"I went to Shanghai on business. Today, the headline APP followed me with an advertisement for china international furniture expo in Pudong. Why does it think I have to buy furniture in Shanghai? My home is not in Shanghai! " Ms. Zhang said in distress situation.

　　However, APP operators don’t care so much. As long as they can accurately push advertisements, the information collected is valuable, especially in advertising promotion.

　　In recent years, fraud cases caused by information leakage are common. According to this survey, after users’ personal information was leaked, about 86.5% of the respondents were harassed by sales calls or text messages, about 75% of the respondents received fraudulent calls, and about 63.4% of the respondents received spam, ranking the top three. In addition, some interviewees have received illegal information such as illegal links, and even more, personal account passwords have been stolen.

　　More than 20% of users never read application permissions and user agreements.

　　How to use and protect personal information, there is actually an agreement between users and mobile APP operators, that is, user agreements and privacy policies need to be signed when registering. However, many users only operate the "next step" all the way when registering, and seldom pay attention to the small words as big as ants.

　　The survey results show that when users install and use mobile apps, few people read the application rights and user agreements or privacy policies, 31.2% of users occasionally read, 26.2% never read, 18.1% always read, and only 8.2% often read. Moreover, among the respondents who have read the application rights and user agreements or privacy policies, only 26.7% of the respondents can read them carefully, less than 30%. In other words, everyone basically has a green light all the way and opens their arms to the APP.

　　Why is this happening? Do users care about their privacy? The survey shows that it is more likely to be a kind of helplessness — — Among the respondents who accounted for 26.2% never read the application rights and user agreements or privacy policies, 61.2% admitted that the main reason why they never read them was that they could not use them without authorization and had to accept them.

　　Recently, the reporter downloaded China Telecom’s online business hall APP on his mobile phone, and found that if he did not agree with the "Telecom User Registration Agreement", he could not use it at all. The National APP WeChat also has this problem. If you don’t agree with the user agreement, you can’t register and use it. However, Taobao, Dianping, Baidu and other apps don’t agree with the user agreement. Although they can’t complete registration and login, and can’t enjoy more sophisticated services, the basic functions can still be used.

　　Even users who have carefully read the agreement are vulnerable to APP operators. The survey shows that after the disclosure of personal information, some respondents will take various measures to protect their rights and interests, such as complaining to consumer associations and relevant administrative departments, and some respondents will choose to negotiate with service providers and give feedback to relevant industry organizations, but in the end, about one-third of the respondents choose to "admit that they are unlucky".

　　Those users who are unable to protect themselves have to take some conservative measures to console themselves. For example, 67.2% of the respondents said that when using the APP, they mainly protected their personal information by filling in part of their personal information, 18% of users used some false information when registering, 24.6% of users installed relevant protection software, and 32.7% of users chose to close the services that could be closed after registration.

　　"On the one hand, users and mobile APP service providers are often in an unequal position, and they can only agree or be forced to agree to format terms and information access rights; On the other hand, although consumers have a sense of self-protection, they do not know how to protect themselves more effectively, and it is often difficult to respond effectively. " Pi Xiaolin said that there is a general trend of over-collection of personal information by mobile apps, and users have many concerns, but they often lack adequate and effective countermeasures, and the protection of users’ personal information and privacy needs to be strengthened.

　　[Global Times comprehensive report] "The Syrian army entered Raqqa province for the first time after two years" — — After the Iraqi army concentrated heavily on attacking Fallujah, an important stronghold controlled by the extremist organization "Islamic State" (IS), the battlefield against IS in Syria also received good news. According to Agence France-Presse reported on the 5th, Syrian Human Rights Watch, a British-based organization, said that under the cover of air strikes by Russian troops, Syrian government forces had invaded the eastern province of Raqqa dominated by IS on the 4th, and the front line was 80km away from the city of Raqqa, the capital of IS. In addition, the Syrian opposition and the Iraqi army supported by the United States also launched offensives against IS in different regions.

　　Agence France-Presse said on the 5th that this is the first time that the Syrian army has entered Raqqa province since its fall in 2014. In June 2014, the "Islamic State" announced the establishment of a "country with a combination of politics and religion", won Raqqa from the Syrian opposition and "established its capital" to implement Islamic law. Since then, IS has almost completely occupied Raqqa province. At the end of May this year, the Syrian opposition "Syrian Democratic Forces Alliance" supported by the United States launched a military operation in the northern part of Raqqa province, and IS militants retreated to Raqqa. On June 1, the Syrian government forces also began to launch a recovery operation in Raqqa province. According to the Syrian Human Rights Watch, at least 26 IS elements were killed, and 9 people were killed in the Syrian government.

　　Russian satellite news network said on the 5th that the Syrian army successfully crossed the border of Raqqa province from the southwest with the support of the Russian Air Force. The BritISh Broadcasting Corporation (BBC) said that in the north of Raqqa, the "Syrian Democratic Forces Alliance" is believed to have deployed 30,000 troops to expel IS armed forces. US officials estimate that there are about 3,000 to 5,000 IS militants in Raqqa. According to reports, Russia has promised to cooperate with the Syrian opposition and the United States to attack. On the 4th, "Alliance" continued to approach Mambiji, another important stronghold of IS, and has captured more than 30 surrounding villages and towns. Mambiji, located in Aleppo province in northern Syria, is an important link connecting Raqqa province and the Syrian-Turkish border.

　　Qatar Al Jazeera said on the 5 th that at present, the eastern, northern and western parts of Raqqa province have been surrounded, but the south IS still connected with other important strongholds occupied by IS. Entering Raqqa province is an important progress, but it takes time to attack the city of Laqqa. Raqqa has a vast territory, so whoever holds Raqqa must be heavily guarded.

　　At present, there is no indication that there is cooperation between Syrian government forces and the opposition. Russia’s "Viewpoint" reported on the 4th that it would be of great military and symbolic significance if the city of Raqqa, known as the capital and base camp of IS, could be captured. Sabet Mohammed, a former Syrian military general, said that the occupation of Raqqa would divide the territory controlled by the Islamic State into several parts and cut off the supply of IS militants who surrounded Deir ez-Zor. He said that before the start of government operations, Russian bombers carried out large-scale bombing of IS positions. However, no matter how the situation develops in the future, in addition to the flag of the Syrian government, government forces will never allow the flag of any organization to be raised in Raqqa, including the "Syrian Democratic Forces Alliance".

　　As of the evening of the 5 th, neither the Syrian government nor the Russian official made a statement on the attack on Raqqa. The Global Times reporter saw in Syria that the local media was also very quiet. Therefore, some analysts believe that the low-key of all parties shows that either this news has yet to be confirmed, or the advantage of government forces is very weak. On the 5th, Syrian government forces supported by Russia launched a fierce battle with anti-government rebels in Aleppo. Western media claimed that 16 civilians were killed when government forces launched air strikes against Aleppo, while Russia claimed that terrorist organizations dispatched armored vehicles to shell civilian areas.

　　“‘ Islamic State ’ In the face of four-front operations, the Associated Press issued a document on this issue on the 5 th, saying that IS is facing attacks from four aspects: the Syrian government forces, the Syrian Democratic Forces Alliance, the Syrian rebels and the Iraqi army. Reuters said on the 5th that IS occupied the cities of Raqqa in Syria and Mosul in Iraq two years ago, calling themselves the capitals of Syria and Iraq, and declared that it would rule all Muslims in these areas. Recently, the Iraqi army has attacked Fallujah and Mosul, two major strongholds occupied by IS, and the Syrian army has advanced into Raqqa province in Syria, and IS is suffering a major blow. On the 4th, the Iraqi army announced the control of Sagravia in the north of Fallujah. However, the battle to recover Fallujah has progressed slowly, IS militants have fought back fiercely, and there are still tens of thousands of people trapped in the local area, which hinders the Iraqi army from continuing to advance.

　　The United Arab Emirates newspaper El Pais said on the 5th that the Iraqi armed forces advancing towards Fallujah will encounter strong resistance from IS, but it is widely believed that it is a matter of time before Fallujah is recovered. Fallujah has been the breeding ground of rebellion since the United States overthrew Saddam Hussein’s regime, and the United States and the Iraqi government have never really controlled the city. "Even if Fallujah IS recovered, the time and difficulty of taming the city is no less than defeating IS."

　　On the 4th, Russian newspaper Izvestia quoted Yuri Jining, an expert from Moscow Institute of International Relations, as saying that at present, all factions in Syria face a common enemy. Therefore, moderate opposition Kurds can cooperate with government forces to fight IS. Without the support of government forces, Kurds would be surrounded by the enemy. In order to jointly attack this enemy, the Syrian government has also made some concessions in consideration of the interests of the Kurds.

　　At the just-concluded shangri-la dialogue meeting, the Russian side also raised concerns about the Syrian situation. According to a report by RIA Novosti on the 5th, Russian Deputy Defense Minister Antonov asked the United States to respond to Russia’s proposal on cooperation in Syria at the "Xianghui". Russian Foreign Minister Lavrov said in a telephone conversation with US Secretary of State Kerry on the 4th that he was worried about the attempt to delay the resumption of negotiations between the Syrian factions. It is necessary to draw a clear line between Syria’s moderate opposition and the "National Front" terrorists as soon as possible. The complex situation in Syria requires Russia and the United States to jointly fight terrorist organizations.

Park Shin Hye’s works have been continuous since her debut as a child star, and with her efforts in the circle for many years, she has successfully transformed into a new generation of Korean drama queen. Park Shin Hye can be said to be loyal in the Korean entertainment circle. On weekdays, there are many friends in the circle, and Song Joong Ki is one of her friends. Let’s take a look at how powerful the opposite sex of the goddess is.

Do you remember Cui Yingdao who came in to bully Che Enshang in "Heirs"? Ouba, a fish cake, also said that it was the happiest for the three actresses in the play to get along with Park Shin Hye in private. They also attended the award ceremony of the National Opera Festival together, and their friendship was perfect.

Park Shin Hye’s closest relative, Lan Yan’s confidant, must be counted as Li Hongji. They are full of friendship and have many loving stories. They often help each other, and they also tease each other when they kiss while helping to shoot the MV.

Park Shin Hye said that the original script was that she kissed Li Hongji, but she felt that she would be laughed at for 100 years, so she changed it to Li Hongji kissing her, and the friendship between friends was full marks.

Jang Keun Suk Park Shin Hye’s cooperation in "It turned out to be a beautiful man" made them become good friends, shooting advertisements together, getting full marks in CP, and often meeting in private.

Park Shin Hye Jung Yong Hwa’s "It turns out to be a beautiful man" and "You are crazy about me" are both TV dramas co-produced by two people. Park Shin Hye, who was busy filming at that time, would go to help Jung Yong Hwa show out all night, with full marks.

Recently, Park Shin Hye, who was busy filming doctors, took a photo of the aid certification on SNS. The aid vehicle supported by his friend Yong Jun Hyung showed us their full friendship.

As a good friend in the circle, Kim HeeChul is of course a good friend with Park Shin Hye. Kim HeeChul and Li Hongji and others also helped her celebrate her birthday ~

Pinocchio, co-produced by two people, not only got full marks in acting, but also the sweet relationship between the two people was exposed by the Korean media. Although both sides denied this statement and said that they were just friends, the Korean media also sent out evidence photos.

On May 10th, in the biggest 10m anechoic chamber in the southwest of Mianyang City, the staff conducted a microwave radiation test on the spot. (Reporter) Li Xiangyu)

     

● To help enterprises tackle key technical problems, Sichuan explored the establishment of the first large-scale scientific instrument sharing platform in integration of defense and civilian technologies, and promoted the open sharing of scientific research resources such as large-scale scientific instruments and equipment.

● Create innovative cooperation platforms. At present, there are 9 major scientific and technological infrastructures built and under construction in the province, ranking among the top in the country, with 151 national scientific and technological innovation platforms and 1,332 provincial scientific and technological innovation platforms.

● Promote the transformation of scientific and technological achievements. Sichuan strives to solve the "first mile" and "last mile" problems of scientific and technological achievements transformation, stimulate the vitality of scientific research in colleges and universities, and at the same time strengthen the transformation of achievements, avoid ineffective research and development, and "research" rather than "development"

First-line tidal observation

It is an important reform task entrusted to Sichuan by the CPC Central Committee and the State Council to systematically promote the comprehensive innovation reform experiment.

In August 2015, our province became one of the eight comprehensive innovation and reform pilot zones in China. Chengde Mian area, which has concentrated nearly 70% of the province’s scientific and technological strength, has taken on the heavy responsibility of promoting implementation. How to rely on the profound scientific and technological "internal strength" to accurately point out the "acupoints" of the transformation of scientific and technological achievements and create a set of beautiful "boxing methods" to promote industrial development through science and technology?

From May 9th, the report group of "Magnificent 70-year Struggle in a New Era —— Journalists Visiting the National Experimental Zone" walked from north to south along Mianyang, Deyang and Chengdu to visit the "Kung Fu Cheats" of Sichuan’s comprehensive innovation and reform experiment.

From static rotation

Open the glass door, help the laboratory technology to insert "wings" and break into the vast industrial sky.

On the afternoon of May 15th, Professor Li Jianjun from the School of Architecture and Environment of Sichuan University opened a message box to reporters in the laboratory. In addition to the scholar’s elegance, it is difficult to hide a capable temperament in him.

"There are many transactions, and they are complicated. Please forgive me." Li Jianjun said. A string of titles on his business card reminds reporters that he is not only the "big cow" of flue gas desulfurization technology in China, but also the operational responsibility of related industrial companies.

Flue gas desulfurization is mainly to convert sulfur dioxide into sulfur trioxide and then into sulfuric acid. Other technologies need to be carried out at a high temperature of more than 400 degrees, and the flue gas needs to be heated. After about 8 years of scientific research, by 2010, the Li Jianjun team has mastered a relatively mature flue gas desulfurization technology, which can be carried out at 50-200 degrees, with environmental protection and cost advantages.

However, the technical achievements have gone out of the laboratory to realize industrialization, but this thin "glass door" is not easy to pass. A slightly embarrassing question is: how to distribute the benefits brought by the results between teams and units? Also, can scientists be good managers of enterprises?

In 2016, Sichuan University promoted the innovation of the transformation mechanism of scientific and technological achievements, and explored the confirmation of duty inventions, that is, recognized the ownership share of scientific researchers’ personal invention inspiration, innovative ideas and realization ability in the final results. As for the team achievements in Li Jianjun, the team and the school distribute the benefits of the achievements transformation according to 85: 15.

Accordingly, the team members raised funds to set up a company, focusing on a link in the industrial application of this technology: the production of catalysts and related supporting services, and after its establishment, it realized an output value of 30 million yuan. "Now hire a professional manager to take care of the company so that the team can continue to focus on the main business." Li Jianjun’s tone is calm. "The school has not talked with the team about redistribution, and it needs to be improved in the refinement of the system."

Let the scientific and technological achievements "realize" and let the scientific research team study calmly. Mianyang’s approach is the same-set up relevant technology trading centers, use professional technical brokers to run errands for the scientific research team, and promote the evaluation, trading and financing of scientific and technological achievements. At present, the center has recruited 71 technical brokers nationwide, mainly responsible for collecting local technology supply and demand information.

Turn emptiness into reality

From patent to mass production, we make moves in the square inch of the transformation of results, which gives birth to "singles" experts in sub-sectors

Carefully picked up two small bottles of transparent liquid, and looked at the light source carefully … The two bottles of liquid with a price difference of twice could not be seen in the eyes of reporters. R&D personnel explained that because the luminous flux difference between the two bottles of liquid is 3%, "the high price can reach 10 thousand yuan per kilogram."

On the morning of May 10th, in the final test site of Mianyang Huabao Dingye Technology Co., Ltd., the crude iron stairs led us to the front of three "big guys". Glassware and metal pipes were connected with each other, and traces of tape fixation could be seen at individual joints.

"These three devices took two years, and it took about 10 million yuan to mature." Touching a sunken pipeline on the equipment, Chen Caihu, general manager of Mianyang Huabao Dingye Technology Co., Ltd., was quite emotional.

In 2016, at a technical achievement conference, Chen Caihu learned that a silicone material technology of China Academy of Engineering Physics was looking for a transferee. After paying 7 million yuan for the technology, it took him three years to get through the road of industrialization and finally made a profit in June 2019.

When a technology moves from laboratory to industrialization, it is necessary not only to optimize the production process to reduce costs and stabilize product quality, but also to identify the market and develop products around market demand. To this end, Chen Caihu set up a research and development team and solved the production process problem in two years. In order to find the market, he conducted a market survey for one year before purchasing the technology, and then conducted product verification with downstream enterprises for three years. "It is to convince the other party that your product quality is excellent and reliable."

Take the LED packaging adhesive market as an example. Compared with the epoxy resin in 100 yuan, the luminous flux of silicone, which is several thousand yuan per kilogram, is larger, which can make the LED brighter. However, processing enterprises dare not rashly adopt new suppliers, which requires product verification, and it takes one year to do it once.

"I feel very lucky, the technology is very good, mass production can be achieved, and the market has given us an opportunity to break the monopoly of foreign brands, but the intervening years are really not easy." Chen Caihu said.

Simplify complexity

Customize the "knife method" and deepen the public production service, so that big countries can also "dance"

The ground part is as high as 27 meters and weighs about 22,000 tons, of which 68 are single parts exceeding 70 tons-the world’s largest 80,000-ton die forging press, which is a well-deserved "big country heavyweight".

This press makes the metal material flow in the die under strong pressure, refines the internal grains, and realizes the overall precision forming of large die forgings. It is mainly used in aerospace, nuclear energy, petrochemical industry, shipbuilding, power and other industrial fields. "For example, in the past, an aviation component needed to weld two pieces. With a large die forging press, it can be formed at one time, making the product more integrated, precise and lightweight." Xie Jing, deputy general manager of China Erzhong Wanhang Company, said.

If the 80,000-ton die forging press is compared to a "treasure knife", it is necessary to rely on Deyang’s strong industrial production service ability to tailor the "knife method" for forging different workpieces.

For example, in order to ensure the accuracy of a C919 product, sichuan engineering technical college took the lead in designing a set of strengthening scheme for high-temperature wear-resistant materials. Through small-scale tests, it took half a year to improve the wear resistance of a set of molds, ensuring the precision control of the product and solving the bottleneck problem for the mass production of C919 products.

At present, Sichuan Institute of Engineering and Technology has three provincial engineering laboratories, which can help similar high-tech equipment and instruments in Chengde Mian to give full play to their hidden value.

In the Robot Application Technology Engineering Laboratory of Sichuan Equipment Manufacturing Industry, the high roof is enough for the drone to take off and take aerial photos inside. The factory building is large, and the processing objects are also large. A dark "round cover" with a diameter of about 3 meters is placed in a bright and modern laboratory, and a large piece of newspaper on it has been polished to reveal the background color.

This is a valve cover used in nuclear power field. When it is cast, it has a layer of black substance on its surface, which needs to be cleaned and polished with a grinding wheel. In the past, these jobs required workers to work at high temperatures. The task undertaken by this laboratory is to replace it with robots. "This is actually very difficult. Industrial robots are suitable for simple and repetitive work, and this work requires robots to identify and plan their own paths." Hu Minghua, head of the laboratory, said.

A yellow industrial robot stood by, with many "weapons and equipment" hanging on it. "This one is equivalent to the robot’s eyes, and this computer is the head." In Hu Minghua’s view, robots, lathes and even 80,000-ton die forging presses are all basic platforms. To use the platform well, a special team is needed to design and develop application schemes. "Our team is entrusted by the enterprise to tailor the solution for it, so that the effectiveness of the platform can be fully exerted." Hu Minghua said.

　　Reporter’s notes

　　Valuable climbing "high" and pursuing "new"

　　In the enterprise interview, I deeply felt the value of the development of industrial mother machine and robot industry chain: constantly climbing to the high end. Yangli Group built a complete set of intelligent equipment for hot die forging to expand its production capacity, and Guiyu Airlines developed high-precision machine tools to meet the domestic market demand; Yawei Co., Ltd. and Yangli Group built the second-level node of national industrial Internet logo analysis, and completed the gorgeous transformation from manufacturer to service provider … … Yangzhou enterprises have laid out new fields such as new energy vehicles, photovoltaics and 5G, developed new markets and expanded new space for industrial chain development. Relying on innovation, industrial machine tools and robot industry chain enterprises are getting rid of the traditional development mode and accelerating the cultivation and development of new quality productivity. Enterprises are the main body in developing new quality productive forces. Twenty-five projects under construction are lengthening and enriching the industrial chain, reflecting that Yangzhou’s excellent business environment is becoming a fertile soil for incubating new quality productivity. This year, our city will carry out six key tasks, speed up the breakthrough of the industrial chain, and create new advantages for the high-quality development of the industrial chain. It is reasonable to believe that the development of industrial machinery and robot industrial chain will usher in a better tomorrow.

　　Industrial machine tool is the "machine tool", which is the foundation of manufacturing industry and has an important supporting position in the national economy; Robot is an important symbol of scientific and technological innovation and high-end manufacturing level, and it is also the new blue ocean of manufacturing industry in the future.

　　Yangzhou industrial machine tool industry has a long history and a solid foundation, forming the characteristics and advantages of taking metal forming machine tools as the main part, cutting machine tools as the supplement, and high-end single (set) equipment to drive the development of complete production lines. Especially in the field of metal forming machine tools, it is unique. Four of the top 10 domestic metal forming machine tool manufacturers are in Yangzhou. However, compared with advanced regions, there are still problems such as small overall scale and insufficient industrial support, which need to be continuously exerted to promote the upgrading of the industrial chain.

　　I have three suggestions: First, promote the backbone enterprises to become bigger and stronger, aim at expanding the industrial scale, and concentrate superior resources to cultivate key enterprises. The second is to consolidate the supply chain foundation of the industrial chain and promote the transformation and upgrading of traditional parts supporting enterprises to intelligent greening; Carry out professional investment promotion in the field of machine tool supporting, and strive to make a breakthrough in the local supporting of key core components. The third is to strengthen the platform construction of integration of production and education, guide key enterprises to strengthen cooperation with institutions of higher learning, and promote the construction of integration of production and education.
