　　Let’s act quickly! (The list of books will be published on China Youth Publishing House WeChat WeChat official account on May 6, 2020. )

　　CCTV News:Mobile phone application software, also known as App, with the rapid development of mobile Internet, the functions and classifications of App are more diverse. In November last year, CCTV news channel exposed the chaos of pornographic content in the "learning App for primary and secondary school students". Recently, parents in Chongqing, Guangdong, Beijing and other places have reported that the chaos of learning apps has come back, and the homework apps recommended by many schools have become hiding places for online games.

　　Recently, Mr. Zhao from Shenzhen told reporters that his son, who is in the third grade of elementary school, uses a mobile phone App called "A Primary School Student" every day because the teacher has to arrange homework on it. Recently, he found that the child continued to hold the mobile phone after completing the homework in the App. When he looked carefully, he found that the interface of online games Appeared in this app.

　　Mr. Zhao provided the reporter with a screenshot of the page of this App. Apart from the tips of "whether the teacher arranges homework", there are also sections such as "Growing World", "Parents’ Reward" and "Tasks". But Mr. Zhao reflected that online games appeared in the section of "Growing World", and children can get certain scores by completing tasks, and the scores can be exchanged for virtual currency, so as to buy props or raise electronic pets to play PK with their classmates. Not only that, users can also choose to pay directly in the "mall" to buy game props. Mr. Zhao is worried that the children are addicted to the games in this App, but in the face of the teacher’s request, he has to agree that the children will continue to use it.

　　Coincidentally, Mr. Xiong from Beijing also told reporters that this "One Primary School Student" homework App was installed under the recommendation of the school teacher. The teacher can arrange homework on it and then send the students’ completion to WeChat group, as long as parents do not follow the requirements, they will be urged. Mr. Xiong said that there are so many settings of "game form" in this App that it is easy to cause children’s buying impulse. In less than two months, he has made 13 purchases at the request of his children and spent more than 1,200 yuan.

　　In the survey, CCTV reporters also found that some operators who study App, in addition to using the guise of teaching to promote games, have a more "slick" approach, which is to transfer the game channel in App to WeChat WeChat official account, and guide primary and secondary school users to places outside the App in an attempt to escape supervision.

　　In September this year, some parents reported that there were a lot of content unrelated to learning in an App called "Interactive Homework". The reporter saw in this App that in one-third of the interface, the scrolling words of "DIY by hand", "Meitu area" and "Twelve constellations" are very eye-catching, and clicking on the "recess" section in the interface will enter the column area of these scrolling words. One of the columns called "Little Mutual Talk" is marked with the following words — — "Words, music and movies hope to become a spiritual place in the hearts of students".

　　After parents reported that these contents would affect students’ learning, "interactive homework" closed the "small talk" section. However, the reporter found that this App has started an article on content rectification. "Interactive Homework" opened the WeChat WeChat official account at the same time as the App, and named it "Homework Little Mutual". On October 13th, the reporter entered this WeChat WeChat official account and found that in addition to the "answer query" column in the "Interactive Homework" App, the "latest game" column was placed in the middle position. Click on it and there will be games such as "circle of friends" and "the richest man", and the "game hall" contains nearly 100 online games.

　

　　The reporter found that in the interface before entering each game, it was written in bold font, "Don’t play the game after finishing your homework?" Do you want to be a nerd! " . In the game called "circle of friends", users get points by throwing dice, and when the points reach a certain number, the game sets up a link of "visiting friends", and a female avatar user marked "online" is recommended by the system to click and visit. At the same time, the game also set up a "world chat" section. The reporter clicked into it and found a lot of information about making friends, some of whom used pictures of scantily clad clothes as avatars.

　　WeChat WeChat official account, an "interactive homework", not only uses games to guide primary and secondary school students to socialize, but also contains a lot of online games with sexual suggestion, sexual temptation and bad value orientation. The reporter saw in a game named "Dafuhao" on the WeChat official account page that users must first choose a role, and after choosing to be the protagonist, the game will actively push a photo link of "Secretary’s Resume", which includes personality characteristics and measurements of women.

　　In the "Game Hall" column of WeChat official account, the reporter found that nearly 100 games can be logged in without real-name registration, and most of them have consumer channels such as "Prop Mall". The reporter randomly clicked on a game called "Jiangshan Beauty". The introduction of this game reads: "This is a palace fighting mobile game developed by original simulation management, and all kinds of beautiful women are waiting for you here." Users only need to authorize QQ number to log in. In the brief introduction of a game called "Emperor Lucky 2", it is even written that "you can experience taking a wife and concubinage, monopolizing power and enjoying the beauty of the world" in the game. After clicking on it, the reporter found that there are a lot of voices and words of sexual temptation in the game.

　　Legal experts pointed out that learning apps use the registered primary and secondary school students’ user resources and transfer them to other platforms, and the practice of profiting from them through a large number of online games has violated the legal and moral bottom line.

　　Editor’s note:Water is the source of life and is vital to human health. Drinking water can promote the body’s metabolism and absorption of nutrients, but drinking it wrong may be harmful to health. Therefore, how to drink water is very particular. Let’s take a look.

　　The misunderstanding of drinking water is constant

　　Last summer, the northern hemisphere continued to suffer from high temperature, and the number of patients with "water poisoning" in hospitals in many regions of Europe doubled. According to the Danish Local Times, some Danes drank a lot of tap water to cool off the heat, which caused them to get sick. Take Hawkbell Hospital as an example, the number of patients with "water poisoning" this summer is 10 times that of previous years. According to local doctors, drinking too much water will increase the water content of blood and reduce the sodium content, which will lead to the imbalance between salt and water. Severe imbalance may cause "hyponatremia", and patients may have brain swelling, headache and other phenomena, and even lead to epilepsy, shock and death.

　　Zhao Feihong, director of the Health Drinking Water Professional Committee of Beijing Health Protection Association, said that when people sweat a lot, in addition to water loss, many electrolytes mainly sodium salts will also be discharged with sweat, and people often drink a lot of water to replenish water. This is a misunderstanding. Drinking pure water alone can’t replenish the missing electrolyte, and even further dilute the electrolyte concentration, which leads to the imbalance of the ratio of water and electrolyte in human body and triggers the body to produce different degrees of stress response. "However, in general, drinking more water will not cause serious problems ‘ Poisoning ’ Only people with poor kidney and cardiopulmonary function need special attention. "

　　Zhao Feihong said that there are still many misunderstandings about people drinking water. First, drinking water too fast and replenishing a large amount of liquid in a short time will increase the burden on organs such as the heart and kidneys, which may easily lead to headache, edema and elevated blood pressure. Second, drinking water is too "ice". When the body temperature is high, it is best not to drink drinks below 5℃. Drinking cold water will stimulate the stomach and lead to stomach cramps and diarrhea.

　　Water accounts for 60%~70% of human body weight, and plays an important role in forming whole body tissues, regulating body temperature, promoting metabolism of various systems of the body, and assisting absorption, transportation and excretion of various substances. Batman, an American doctor of medicine, recorded many studies in the book "Water is the Best Medicine", which proved that healthy drinking water can relieve hypertension, diabetes, allergies, asthma, cancer and other diseases. He once cured more than 3,000 patients with water.

　　How to drink water correctly

　　When you feel thirsty, the water loss of adults is about 2% of your body weight, and that of children is about 2%~5%. At this time, your body functions begin to be affected. Lack of water can also lead to loss of appetite, depression, dry skin, hoarseness and general weakness, which can be life-threatening in severe cases. Zhao Feihong suggested that you should develop the habit of taking the initiative to drink water, and don’t wait until you are thirsty. Drinking water should follow the principle of "small amount and multiple times": 100~150 ml is suitable for each time, and the interval is about half an hour; Drinking water with a small mouth is more thirst-quenching than pouring water with a large mouth, which is beneficial to human absorption.

　　There are four best times to drink water. After getting up in the morning, around 10 am, 3-4 pm and before going to bed at night, it is currently recognized as the four "best drinking periods" in a day.

　　Zhao Feihong explained that people do not drop water during sleep, and the formation of nocturia and the loss of water through breathing and skin make the body in a physiological state of water shortage, which leads to the increase of blood viscosity and the accumulation of metabolites in the body. Therefore, drinking a glass of water half an hour before going to bed can alleviate the above phenomenon and reduce the risk of cerebral thrombosis. Drinking a glass of water after getting up in the morning takes only 20 seconds, and water can enter the blood, which makes the blood dilute rapidly and improves the water shortage at night.

　　At least 1.5 liters per day. According to Dietary Guidelines for China Residents (2016), the recommended daily drinking water for adults is 1.5~1.7 liters. Gu Chuanling, deputy secretary-general of the Capital Health Food Nutrition Society, said that people’s daily drinking water can be appropriately increased according to the following factors:

　　1. Living environment. In hot weather, people sweat more and lose water faster, so it is necessary to increase water supply. It is easy to dry in autumn and winter, and in the heating room in northern winter, the water evaporates quickly, so it is necessary to increase the amount of drinking water.

　　2. Dietary factors. The diet is salty, and when the human body discharges excess salt, it needs to consume more water; If you eat food containing more protein, your blood osmotic pressure will increase slightly, and you need extra water to excrete the urea produced by protein. At these times, you need to pay attention to drinking more water.

　　3. Physical condition. When a cold has a fever, the human body will lose a lot of water in the form of sweating, so it is necessary to increase the amount of water.

　　Boiled water is best.

　　China Nutrition Society recommended that boiled water is the most suitable drinking water for human body. American scientists have found that when the boiled tap water is cooled to 25~30℃, the chlorine content is the lowest, and the biological activity of the water is also increased. It can easily penetrate the cell membrane, which can promote the body’s metabolism, enhance immune function and improve the body’s disease resistance.

　　Sweet drinks, functional drinks, fruit juice, strong tea and coffee can’t completely replace drinking water. Zhao Feihong said that all kinds of sweet drinks and fruit juices are high-sugar and high-calorie drinks. The human body needs to consume more water to complete metabolism and cannot replenish water well. Functional drinks, strong tea and coffee all contain caffeine, which has diuretic effect in itself and is not conducive to human hydration.

　　Special people pay attention to drinking water

　　Children. Dietary Guidelines for China Residents, Balanced Dietary Pagoda for Preschool Children in China and Dietary Guidelines for School-age Children in China suggest that the water demand for children under 10 years old varies with age: 6 months to 1 year old, and the total daily water intake is 900 ml (milk/food+drinking water); 1~2 years old, the total water intake is 1300 ml (milk/food+drinking water); 2~3 years old, drinking 600~700 ml; 4~5 years old, 700~800 ml; 5~7 years old, 800 ml; 7~10 years old, 1000 ml. Gu Chuanling reminded that children’s initiative to drink water in time is generally poor, and they like to drink sweet drinks. Parents should do a good job of monitoring and remind their children to drink water in time.

　　Lactating women. About 90% of milk is water, and milk secretion is closely related to the daily intake of water. Drinking more water under the condition of ensuring balanced nutrition is beneficial to milk secretion. Gu Chuanling said that they are generally recommended to drink more water than ordinary women, about 2.1 liters per day.

　　Old man. Old people tend to urinate frequently, and if they don’t drink water regularly, they are prone to thick blood and high blood fat, which will eventually cause a series of metabolic diseases. Therefore, the elderly should drink water frequently, and the amount of drinking water should be increased accordingly, which can be judged according to the color of urine: if the urine is light yellow, 250 ml of water should be replenished in time; If it is brown, it means that the body is seriously short of water, and you should drink 500 ml of water.

　　Office workers. Office workers can replenish 200 ml of water in time after arriving at the company every day, which is conducive to promoting brain activity and working concentration. In addition, office workers who sit indoors for a long time are prone to get fat. Drinking 200 ml of water half an hour before meals is conducive to increasing satiety and reducing food intake to some extent.

　　Manual workers. Athletes and outdoor workers need to replenish water in time after a lot of physical activities. Zhao Feihong suggested that these people can properly replenish water about half an hour before physical activity. During the activity, they can replenish water with a small amount of water. After the activity, they are not in a hurry to replenish water. After a while, they can replenish water and drink some light salt water appropriately.

　　Poor spleen and stomach, drink less water.

　　It is recorded in the medical book "Four Sages Heart Source" in Qing Dynasty: "Shui Gu enters the stomach, the spleen and yang are grinded, and the dregs are passed down, but for feces drowning, the essence is served, and it becomes qi and blood." If the spleen yang is insufficient (spleen yang is the function of spleen and stomach), the digestion and absorption of water is weak and it cannot be turned into qi and blood. People with poor spleen and stomach, such as loss of appetite, nausea and vomiting, frequent hiccups, abdominal distension and diarrhea, epigastric discomfort and other symptoms, had better drink less water in the morning to avoid further affecting the function of spleen and stomach.

　　Be careful when drinking water because of lung dysfunction.

　　Traditional Chinese medicine believes that besides breathing, another important function of the lung is "attending festival", including "dredging water channels". "Waterway" refers to the way that water and liquid move, that is to say, the lung can regulate the metabolism of water and liquid, mainly through the spreading and descending of the lung, and transport body fluid to all parts of the body by using lung qi, which can also promote the water and liquid to be lost to the bladder, so as to keep urine flowing smoothly. If lung function is impaired, such as frequent chest tightness, shortness of breath, wheezing and palpitation, cough with excessive phlegm, nasal congestion and runny nose, etc., water metabolism will also be poor, and drinking water indiscriminately will aggravate symptoms.

　　Traditional Chinese medicine believes that the kidney controls water and the bladder controls the gasification of water. Kidney plays a key role in regulating and maintaining water-liquid balance in the body. If there is a problem with kidney function, pay more attention to drinking water, otherwise there will be edema and unfavorable urination. When there is no need for drinking water, don’t force yourself to drink water, but keep your body in a state of peace of qi and blood.

　　Drinking too much water increases the burden.

　　Many chronic patients have thick blood and hope to dilute it by drinking more water. In fact, water can’t enter blood vessels immediately. Traditional Chinese medicine believes that the human body is a circular whole, and the metabolism of water should be completed under the coordination of various organs and tissues. If there are problems in the gasification of triple energizer, the transfer of viscera and the operation of qi and blood, water will not achieve the purpose of diluting blood, but will increase the burden on the heart, lungs, spleen and kidney. Dietary Guidelines for China Residents (2016) suggests that the daily drinking water should be kept at 1500~1700 ml.

　　Huang Yuanyu, a famous doctor in the Qing Dynasty, said: "If qi does not turn into water, it will stagnate on the upper side and become phlegm; if water does not turn into qi, it will stop accumulating on the lower side and become drinking. Generally speaking, yang deficiency leads to soil failure, and the golden water is swollen, all of which have the disease of retention of phlegm and retention of drink. Covering the phlegm and drinking, corruption and stagnation hinder the road of qi and blood around the week, and the spirit of the spirit is close to the aid. All diseases start and the changes are constant. " It means that if there is no yang, such as yang deficiency and spleen deficiency, and lung and kidney are not transported, water will stagnate into phlegm and form phlegm-drinking disease. Phlegm can block the circulation of qi and blood, leading to many diseases. People who often drink too much water have a heavy burden on the spleen and kidneys, and tend to age faster than others, and some chronic diseases will come faster and more than others.

　　Traditional Chinese medicine believes that the accumulation of water and fluid in the body will also form phlegm, and further accumulation of phlegm can become phlegm nuclei, such as scrofula, gall tumor and other diseases; Or form nodules and lumps with blood stasis. In clinical practice, some patients with cyst have reduced curative effect due to improper drinking water, and the curative effect will be obviously improved after changing improper drinking habits.

　　Phlegm drinking and phlegm turbidity are unique concepts of traditional Chinese medicine, which can be divided into tangible and intangible categories. Tangible, sticky is called phlegm, and thin is called drinking. Invisible phlegm and drink can cause many symptoms, such as dizziness, nausea and vomiting, shortness of breath, chest tightness, palpitation or madness, coma, etc., but no substantial phlegm and drink can be seen. Modern medical research has found that phlegm is related to many diseases such as body immunity, hypertension, hyperlipidemia, coronary heart disease, cancer, asthma and mental illness.

　　Four Special Reminders of Drinking Water

　　1. Don’t drink a lot in a short time. Drinking a lot of water in a short time will increase the amount of urination and perspiration. The former will increase the burden on the kidneys, while the latter will cause excessive loss of salt in the body, leading to electrolyte disorder.

　　2. Clear and colorless urine means enough drinking. How to judge whether you have drunk enough water, it is recommended to observe your urine color every day: if it is light lemon color, it means that the water in your body is in the best state; If the urine is clear and colorless, the water intake should be slightly reduced; If the urine is yellow, you need to replenish water in time.

　　3. Don’t drink before and after eating a big meal. People’s stomach space is limited. If you drink a lot of water before or after meals, it will occupy the space, causing abdominal distension and abdominal pain, which is not conducive to gastrointestinal peristalsis and leads to indigestion. Under normal circumstances, it is recommended to drink water half an hour after meals.

　　4. Avoid drinking immediately after long-term exercise. Drinking water immediately after exercise will lead to a sudden increase in blood volume in the body and increase the burden on the heart. A large amount of water stored in the stomach will also affect the rise and fall of diaphragm, causing discomfort such as chest tightness and asthma. It is suggested to sit down and rest for 10 minutes after exercise before drinking water to give the body a buffer time; At the same time, just drink 150 ~ 200ml each time, and don’t drink too much at a time.

　　Recently, Bozhou Everbright Green Bioenergy (Guoyang) Co., Ltd., which is characterized by unconventional water utilization, was named as the tenth batch of provincial water-saving enterprises by Anhui Provincial Water Resources Department and Provincial Department of Economy and Information Technology.

　　Based on the principle of "zero" emission, the enterprise has implemented the best water-saving scheme in all water-using links, and consolidated management and overall distribution of multiple water supply systems for production, living, greening and fire protection. All the production links use reclaimed water from the sewage treatment plant in Guoyang Economic Development Zone, with an annual water intake of about 450,000 cubic meters, which is mainly used for power generation circulating cooling and desalting water production and preparation; Covering an area of 193 mu, the factory area has achieved global rainwater collection, in which an open underground rainwater collection pool has been built, and all rainwater, road washing water and backwashing water are collected into the rainwater collection pool for reuse. The index of water consumption per unit product is better than the advanced value of industrial water consumption quota in Anhui Province, which sets a water-saving benchmark for similar enterprises. In recent years, Bozhou City has continued to establish water-saving enterprises in high-water consumption industries and key water-using enterprises, strictly supervised daily water intake and water saving, encouraged and supported enterprises to increase unconventional water utilization, strived to reduce water consumption per unit product and effectively reduced waste water discharge.

　　In the next step, Bozhou will continue to improve the water-saving management mechanism and strengthen water-saving management as a guarantee, focusing on water-saving technological transformation and project construction, and cultivate more water-saving enterprises with distinctive highlights, making new and greater contributions to the city’s water-saving emission reduction and green development.

On August 22nd, the Japanese people held an emergency rally in front of the Tokyo Prime Minister’s residence to protest against the government’s disregard of public opinion to start discharging nuclear polluted water into the sea.

　　"No discharge of nuclear polluted water!" "Listen to the voice of fishermen!" "Don’t pollute the sea!" Yesterday, many Japanese people shouted slogans in front of the Japanese Prime Minister’s residence in Tokyo in the rain to protest against the government’s decision to start the Fukushima nuclear polluted water discharge into the sea on August 24 that morning. Earlier, Yasin Sakamoto, president of the National Federation of Fishery Associations, reiterated in a meeting with Prime Minister kishida fumio that the position of anti-nuclear pollution water discharging into the sea remained unchanged.

　　Kishida finalized the start date of sea discharge.

　　The Japanese government held a cabinet meeting on the morning of 22nd, and kishida fumio said that as long as the weather and marine meteorology are fine, the sea discharge will be started on 24th. He claimed that the Japanese government will be responsible for discharging the sea in the next few decades until all the so-called "treated water" is disposed of.

　　After returning home from the meeting at Camp David in the United States, Japan and South Korea on the 19th, kishida fumio accelerated the plan of discharging nuclear polluted water from Fukushima into the sea. On the 20th, he inspected the Fukushima Daiichi nuclear power plant; On the 21st, he met with representatives of fishing groups such as Japan National Fisheries Association and Fukushima Fishery Association at the Prime Minister’s residence, trying to gain understanding. However, the delegates attending said that the fishing industry will continue to oppose the discharge of nuclear polluted water into the ocean without the understanding of the people.

　　On April 13, 2021, the Japanese government decided to filter and dilute millions of tons of nuclear contaminated water from the Fukushima Daiichi nuclear power plant and discharge it into the sea, on the grounds that the storage tank of nuclear contaminated water in the Fukushima Daiichi nuclear power plant is almost full. According to Tokyo Electric Power Company, the operator of the Fukushima Daiichi nuclear power plant, by the summer and autumn of this year, there will be "nowhere to store" nuclear polluted water, and failure to discharge it into the sea will delay the scrapping of nuclear power plants.

　　Trigger an emergency rally to protest.

　　On the morning of the 22nd, many Japanese people gathered in front of the Prime Minister’s residence to protest against the Japanese government’s decision to start discharging nuclear polluted water into the sea. One of the organizers, Xiu Xiushu, said that the Japanese government’s forced decision to promote the discharge of nuclear polluted water into the sea was extremely angry. The Japanese government calls the nuclear polluted water to be discharged "treated water", but no matter how it is treated, the nature of nuclear polluted water will not change. Long Xiushu stressed that people who oppose the sea exclusion will continue to speak out strongly and fight with all their strength in the future.

　　Koko Furukawa, whose hometown is near the Fukushima nuclear power plant, told reporters that she was forced to take refuge for a long time because of the accident at the Fukushima nuclear power plant. Prime Minister kishida fumio claimed that he would be responsible for the whole process of discharging nuclear polluted water into the sea, but he was "not qualified, authorized or entitled" to take responsibility.

　　In 2015, the Japanese government and the Tokyo Electric Power Company promised the fishermen in Fukushima that they would not dispose of the nuclear polluted water without authorization until they were understood by the stakeholders. Mizuho Fukushima, leader of the Social Democratic Party of Japan, criticized that the government trampled on the agreement reached with stakeholders. The Japanese government ignored the opposition and decided to start the sea discharge, which is a "brazen move."

　　According to the results of a national public opinion survey conducted by Japan’s Kyodo News Agency from 19th to 20th, more than 80% of the respondents thought that the Japanese government’s explanation on nuclear polluted water was "insufficient".

　　Ignore fishing groups and reiterate their opposition

　　Masanobu Sakamoto, president of the National Federation of Fishery Associations of Japan, reiterated on the 21st that there is no change in his opposition to discharging Fukushima nuclear polluted water into the sea without national understanding.

　　Yasin Sakamoto made the above statement in a meeting with kishida fumio on the same day. Although kishida fumio promised during the meeting that he would continue to take necessary measures to help the fishermen, Sakamoto Yasin still expressed his position against the discharge of nuclear polluted water into the sea.

　　In addition, in a meeting with Japanese Minister of Economy, Trade and Industry Yasutoshi Nishimura on the same day, Sakamoto said that once the nuclear polluted water starts to be discharged into the sea, it will probably last for decades, and Japanese fishermen are very uneasy and worried about this.

　　"The sea is the work place of fishermen, and no one has the right to pollute the sea." On July 30th, the first phase of the 2023 World Conference on the Prohibition of Atomic Bombs and Hydrogen Bombs, sponsored by the Japanese National Conference on the Prohibition of Atomic Bombs and Hydrogen Bombs, was held in Fukushima City. Xiao Ye Chunxiong, a fisherman from Shinichi-CHO, Fukushima Prefecture, said this at the meeting.

　　Regarding the scheme of discharging nuclear polluted water into the sea, Xiao Ye said that once the sea is polluted, it cannot be removed. "It is most reassuring to keep the nuclear polluted water in a water storage tank.".

　　Zhuangzi Gongjiang, whose husband is a fisherman, said that she was very shocked to hear people around her say that if she started to discharge, she would not let the children eat fish.

　　Suzuki, whose husband and son are fishermen, expressed anxiety about the future of Fukushima fishery. She said, I don’t know whether to let my son continue to engage in fishing, let alone what will happen to my grandson’s generation.

　　pay close attention

　　Foreign Ministry spokesperson: We have made solemn representations to the Japanese side.

　　In response to the Japanese government’s decision to start the discharge of Fukushima nuclear polluted water into the sea recently, Foreign Ministry spokeswoman Wang Wenbin said at a regular press conference on the 22nd that Japan’s move was extremely irresponsible. China has made solemn representations to Japan and will take all necessary measures to safeguard the marine environment, food safety and public health.

　　Wang Wenbin said that despite the serious concern and resolute opposition of the international community, the Japanese government insisted on announcing that the Fukushima nuclear polluted water would be discharged into the sea on August 24, openly transferring the risk of nuclear pollution to the whole world, and putting its own self-interest above the long-term well-being of all mankind. This is extremely selfish and irresponsible. China is seriously concerned and strongly opposed, and has made solemn representations to Japan.

　　He said that for more than two years, the legitimacy, legality and safety of the Fukushima nuclear pollution water discharge plan have been questioned by the international community. Up to now, the Japanese side has not solved the major concerns of the international community about the long-term reliability of the nuclear polluted water purification device, the authenticity and accuracy of the nuclear polluted water data, and the effectiveness of the monitoring arrangement for discharging the sea. China and other stakeholders have repeatedly pointed out that if the nuclear polluted water is safe, there is no need to discharge it into the sea, and if it is unsafe, it should not be discharged into the sea. It is unfair, unreasonable and unnecessary for Japan to force nuclear polluted water into the sea.

　　"Regrettably, the Japanese side turned a deaf ear to international voices, deliberately created the illusion that the sea discharge was safe and harmless, and even unreasonably accused neighboring countries that expressed legitimate concerns. What it did has aroused strong indignation among neighboring countries and domestic people." Wang Wenbin said.

　　Wang Wenbin said that the ocean is the common property of all mankind, and the Japanese side should not be allowed to dump nuclear polluted water. China strongly urges Japan to correct its wrong decision, cancel its plan to discharge nuclear polluted water into the sea, communicate with neighboring countries in good faith, dispose of nuclear polluted water in a responsible manner and accept strict international supervision. China will take all necessary measures to safeguard the marine environment, food safety and public health. Text/Xinhua News Agency

　　 China Youth Daily Zhongqing Online Reporter Wang Yejie

　　 If the weather is fine, China’s first domestic civil large passenger plane C919 will start its first blue sky trip on May 5, which marks a major leap in the field of civil aviation in China.

　　 China’s civil aviation industry has been in a state of "buying imported goods" since the research and development of the domestic "Yun Shi" passenger plane stopped in the 1970s.

　　 The turnover of civil aviation passengers in China has rapidly climbed from 23.048 billion person-kilometers in the early 1990s to 727.07 billion person-kilometers in 2015, with a compound annual growth rate of 15%.

　　 C919 was developed in 2008, and now it is about to make its first flight. Every "growth process" of C919 has attracted much attention. Behind this big domestic bird, groups of young talents are also growing sturdily. From the "post-70s" in the early 20th century to the "post-80s" and "post-90s" now, behind the first flight of C919, there is a solid backing composed of young talents.

　　 Data from Commercial Aircraft Corporation of China (hereinafter referred to as China Commercial Aircraft Corporation) show that more than 70% of the company’s young people are under the age of 35. When experts from related international fields visited Comac in China, they expressed such feelings: "The impressive thing about China Big Aircraft is not only the technology, but also the young people who are eager to fly behind it!"

　　The domestic large passenger plane C919 was tested at Shanghai Pudong Airport for high-skid lifting of the front wheels. Xinhua news agency

　　 570 aircraft orders and 60% localization rate

　　 Speaking of C919, I have to talk about the topic of "localization". Fans of the aviation industry may not forget the low standard of "the localization rate is more than 10%" at the beginning of the C919 project, and even this low requirement was considered by some senior aircraft enthusiasts to be difficult to achieve at that time; Today, the finished products delivered off the assembly line not only get 570 orders, but also have a localization rate of nearly 60%.

　　 Some people question that the core engine and other components are all imported. Is the C919 a domestic product?

　　 China Youth Daily Zhongqing Online reporter learned that the nose of C919 comes from Chengdu Aircraft Industry Group, the wing comes from Xi ‘an Aircraft Industry Group, the front and rear fuselage comes from Nanchang Hongdu Aviation Industry Group, and the front section of the rear fuselage comes from Shenyang Aircraft Industry Group.

　　 As for the "kernel" of large aircraft, such as engine, communication and navigation equipment, C919 aircraft chose two paths — — First, foreign original factories and domestic joint ventures; Second, the original import, to a certain extent, to achieve partial domestic, and finally to achieve full domestic.

　　 "Realizing all localization in the end" is the "technical market threshold" set by Comac China when purchasing original imported products. That is to say, once a product is purchased by Comac China, there is only one final "outlet" — — Gradually localized. This is the basic agreement between the product manufacturer and Comac China.

　　 At the beginning of the C919 project, Li Keqiang, Premier of the State Council of the People’s Republic of China set a basic principle for domestic large aircraft — — Independent design, system integration, global procurement, and gradual domestic production.

　　 Many people think that assembling some imported products is actually not too difficult and has no technical content. However, an interview with China Youth Daily and Zhongqing Online reporter found that for China people who have not been exposed to the research and development of civil large passenger aircraft for more than 30 years, the design, production and manufacturing process of C919 itself is full of innovations and challenges.

　　 Take fiber material as an example, 15% of the fuselage of C919 is made of resin-grade carbon fiber material, which is the first time that this material has been widely used in large-scale civil passenger aircraft, and the utilization rate of this material in traditional large-scale passenger aircraft is only about 1%.

　　 Others don’t use it, not because the material is not good, nor because the price is too expensive, but because this material requires too high installation accuracy, ordinary people can’t complete the accuracy required for "docking" with this material, so it is not used much.

　　Gao Yuan (first from the right)

　　 Gao Yuan, deputy director of the aircraft assembly workshop of Shanghai Aircraft Manufacturing Co., Ltd. (hereinafter referred to as Shangfei Company), told China Youth Daily and Zhongqing Online reporter that the resin-grade carbon fiber material used in C919 is light in weight, and its weight can be 80% lighter than that of ordinary traditional materials under the premise of the same strength; Its fatigue life is also longer. Generally, the service life of metallic silver material is 20 years or 60,000 flight hours, but it can reach 30 years or 90,000 flight hours, and the structural life can be increased by 50%.

　　 One problem is that when this material is used in aircraft manufacturing, the docking accuracy required is three or four orders of magnitude higher than that of rockets, and the method of realizing "accuracy" by traditional measuring tools is not applicable.

　　 In the manufacturing process of C919, China people realized the automatic docking of large parts for the first time. Through laser positioning and tracking, the docking accuracy can be two orders of magnitude higher than in the past.

　　 With the "shell", what about the core?

　　 For example, if you cut a small hole in the outer shell of an airplane and fill it with a composite material, to what extent do you think it should be filled? The requirement of C919 is that it is invisible to the naked eye, and the "step difference" between the "patch" and the raw material is within 0.08 mm..

　　Wang Hui (center)

　　 What is the concept of 0.08 mm? It is several orders of magnitude thinner than the thickness of mobile phone film. "Invisible to the naked eye, experienced masters can touch the difference with their hands." Wang Hui, deputy director of the manufacturing engineering department of Shanghai Aircraft Corporation, told the reporter that without a certain technical level, even if a Boeing 747 is disassembled and put in front of you, it is impossible for you to assemble it again.

　　 Wang Hui said that the Manufacturing Engineering Department is equivalent to a translator, and it has to translate the drawings of the upstream aircraft design company into construction plans and technological processes that front-line workers can understand. Even if it is such a small and insignificant step, China people will go abroad to learn from it.

　　 Before C919 started construction, COMAC cooperated with McDonnell Douglas to manufacture aircraft of McDonnell Douglas 82 and McDonnell Douglas 90. In this process, McDonnell Douglas provided the process flow, and COMAC was responsible for the production. To a certain extent, the cooperation with McDonnell Douglas makes the manufacturing engineering department of Shangfei Company grow gradually, and finally it can master the process independently.

　　 Even so, some people will feel disdainful. Isn’t it just to build a shell? How much of the "core" is the result of China people?

　　Zhou Qiwei

　　 Zhou Qiwei, 30, has the most say in this. All the cable-related departments on C919 are under his control and his team’s control. There are 24 of them, with an average age of around 30, but they are responsible for the most critical link in the normal operation of a plane — — 725 cables are arranged and laid, and 150,000 parts are installed and assembled.

　　 These cables, like "nerve lines" and "blood vessels" in the human body, will lead to "organ" failure if they are not careful. The display may not be on, the throttle lever may be out of control, and the joystick may fail … … And all wiring, not a single drawing can solve the problem.

　　 "Drawings are subjective designs, and everything is subject to the real thing." Zhou Qiwei told reporters that wiring often reflects the actual situation to the design team, and many design ideas cannot be realized in the actual wiring process. At this time, the wiring team also has to undertake some "design functions", propose modifications and feedback to the designer, and then wait for the designer to re-issue more realistic drawings. "Without talent, you can’t do this job."

　　 The young and beautiful Gong Wenxiu is also responsible for the control of the "core" inside the aircraft. She is a member of the configuration management team of Shanghai Aircraft Design and Research Institute. Her job is to adjust the technical state of the whole machine to the best before the first flight. The navigation and communication system of aircraft can not be used directly after being bought and installed. It needs constant debugging and constant correction of system errors before it can operate normally.

　　 Gong Wenxiu’s job is to "correct mistakes". Every inspection, she has to carry a thick stack of process specification materials in her hand and check them one by one. She and her team have to evaluate some system functions that cannot be realized for some reason. Why can’t they be realized? What is the impact on the first flight? Is it necessary to achieve it? Then give feedback.

　　Scale testing machine

　　 What does "939, 949" look like after C919?

　　 If the aforementioned "handsome men and beautiful women" are all preparing for the first flight of C919, then the following one is preparing for the future "C939 and C949".

　　 His name is Zhang Chi, deputy head of the future product and technology research team of Beijing Civil Aircraft Technology Research Center (hereinafter referred to as Beiyan) of Comac China. He and his team are responsible for the "future model" of the C919. They gave themselves a rather dreamy name — — Dream studio, responsible for the "Lingque" project.

　　 The "Lingque" project, to put it more popularly, is to design and develop a scaled-down large aircraft. This "Lingque" aircraft is more futuristic, unmanned and small, and the cost of an aircraft is less than 1% of that of the C919. But it carries the future of China’s big plane dream.

　　 Lingque aircraft is a scaled verification model. It costs a lot to build a large plane and bears high risks in the field of innovative technology, but the smaller version of the "Lingque" can be more "dreamy" with low cost.

　　 The latest "Lingque B" fuselage and wings are integrated, which is more economical and comfortable. Its tail has only two pieces, which is less resistant than the general three-piece tail plane.

　　 This team, which is all composed of young people around the age of 30, is now doing research and development to solve the world-wide problems such as expensive air tickets and high fuel consumption of aircraft.

　　Franky Zhang

　　 "Real innovation is not afraid of failure." Zhang Chi said that this team often received suggestions from peers in the past, "Is your plan feasible? Maybe not? "

　　 However, Zhang Chi told reporters that in all kinds of discussions, Dream Studio has made nine scale testing machines since 2012, and there have also been cases in which small planes got out of control after take-off and ground dispatching was unsuccessful. "Without failure, it is not innovation, that is called imitation. We don’t do this. "

　　 Zhang Chi said that youth is the capital of Dream Studio.

　　 China Youth Daily Zhongqing Online reporter learned that Comac China has set up a total of 349 youth commandos, such as the young commandos for aircraft-level joint test of the C919 project of COMAC, and the young commandos for the assembly of the C919 large passenger aircraft system in the aircraft assembly workshop of COMAC, and named 60 youth civilization numbers, such as the composite material/structure research team of the North Research Center and the young technical team for field engineering of the test flight center.

　　 Comac youth played a great vanguard and vital role in the flight test evidence collection of ARJ21 passenger plane, route demonstration operation, design and development, final assembly and manufacturing of C919 large passenger plane, and preparation for the first flight — — Ten youth innovation and entrepreneurship teams, with more than 230 members and an average age of less than 30, have undertaken 37 key technical problems of civil aircraft, including the control law of C919 large passenger aircraft.
