Hypertension, depression, insomnia … … Even cancer, if someone tells you that there is a "hydrogen inhalation" therapy that can treat these symptoms, do you believe it? Hydrogen is a flammable gas. Does it really have such a "magical" effect when inhaled into the human body? What is the scientific principle behind it? Is it really effective or a psychological effect to treat diseases by absorbing hydrogen?

　　The reporter recently learned in an interview that this kind of "hydrogen therapy" is gradually being valued by the medical community, and the selective antioxidant properties of hydrogen are the key to the so-called "cure all diseases".

　　Why do people get sick?

　　The main reason is the imbalance of oxidation and reduction in the body.

　　To understand why hydrogen can cure diseases, we must start with why people get sick.

　　We should know that the human body is always in a dynamic balance with the surrounding environment. Under the action of pathogenic factors, such as bacteria and radiation, the original balance is broken, and the body is damaged, resulting in pathological changes in the function, metabolism and mental structure of tissues and organs, resulting in clinical symptoms and signs.

　　When human cells are oxidized, they will form oxidative damage. Medically speaking, it is because of internal and external factors that a large number of free radicals in the body erupt, which is called oxidative stress.

　　Free radicals are atoms, groups or molecules containing unpaired electrons. Free radicals themselves are essential substances to maintain normal life. Free radical reaction is the basis of energy metabolism. When people inhale oxygen and eat food, energy substances and substances that promote energy conversion undergo oxidation reaction in the body, thus producing a large number of free radicals. Free radicals in the human body are constantly produced, and will be continuously removed and maintained at a normal physiological level. Once there are too many or too few free radicals, it will cause adverse effects and even harm to the body.

　　When the oxidation degree of cells exceeds the antioxidant capacity of cells to remove oxides, it will form an imbalance between oxidation system and antioxidant system, that is, redox imbalance. Excessive free radicals, especially toxic reactive oxygen species, will begin to attack biological macromolecules and cause tissue and cell damage. Therefore, oxidative damage is the root cause of various diseases and body aging. Taking the treatment of human inflammation as an example, it is generally believed that scavenging oxygen free radicals is the most fundamental way to alleviate inflammatory reaction.

　　Principle of treatment:

　　Hydrogen can scavenge human toxic free radicals.

　　Xu Kecheng, a domestic oncologist and honorary president of Fu Da Cancer Hospital affiliated to Jinan University, told the Yangcheng Evening News reporter that "hydrogen therapy" is a new therapy that is gradually being valued by the medical community. The medical community has carried out more and more research on how many diseases, to what extent, and whether there are side effects.

　　Xu Kecheng introduced that no matter what kind of diseases people suffer from, there is a common factor, that is, the emergence of toxic free radicals in the body. Free radicals (reactive oxygen species) are divided into good and bad ones. Japanese scientists have found that hydrogen can specifically remove bad free radicals. Because one of the most typical and important chemical properties of hydrogen is its reducibility, which can selectively neutralize toxic free radicals. From the analysis of disease mechanism, oxidative damage is the most basic pathophysiological process of almost all diseases. Therefore, since hydrogen is a selective antioxidant, it is likely to have a therapeutic effect on most human diseases.

　　Why does hydrogen have selective antioxidant properties? It turns out that the reducibility of hydrogen is very weak compared with various reductants in the process of cell metabolism. According to the law of redox priority: for the same oxidant, when there are multiple reductants, it usually reacts with the reductants with the strongest reductants first. Therefore, in the normal process of cell metabolism, hydrogen basically has no effect. However, if it is in abnormal cells, the situation is different. For example, in tumor tissue cells, because a large number of free radicals are produced, the normal metabolic reaction cannot be carried out, so other reducing substances are insufficient, which gives hydrogen a chance to react chemically with free radicals, and the result is to cancel out unpaired electrons in free radicals — — Most unpaired electrons of free radicals come from oxygen atoms — — They can react with hydrogen to produce water, a stable substance, and free radicals that lose oxygen atoms become stable substances in this process.

　　Small side effects,

　　Because hydrogen itself is inactive

　　In Xu Kecheng’s Guan ‘ai Health Studio in Guangdong Province, the reporter saw that the seats next to the 15 "hydrogen-absorbing machines" set here were all filled with people who "sucked hydrogen" with trachea in their noses. The staff told the reporter that this machine can electrolyze water into a mixed gas with 66% hydrogen and 33% oxygen only by adding pure water or distilled water. The patient only needs to take a deep breath and inhale the gas into the body to complete a course of treatment. The time for each "hydrogen inhalation" course is at least one and a half hours. A 62-year-old Chen Yi told the reporter that she was diagnosed with gastric cancer several years ago. After a series of radiotherapy and chemotherapy treatments, the whole person became extremely weak. After starting to suck hydrogen in early August this year, she found that her physical condition had improved significantly. "After the first hydrogen inhalation, it was a sweat when I got home; After insisting on smoking for three times, I found that the sleep that I woke up once an hour has improved. Originally, Qing Wu’s face has also improved, and his physical strength has gradually recovered. Now he can go for a walk in the community every day. " Another Abreu also told reporters that he had liver cancer four years ago, and later had an operation to remove it. I didn’t expect it to recur last year. After being recommended to absorb hydrogen, the most obvious change is that sleep is better and the spirit is much better.

　　It turns out that in terms of anti-tumor, tumor cell walls produce more reactive oxygen species than normal cells, which affects cell proliferation, DNA synthesis and angiogenesis, and oxygen free radicals, as "second messengers", play an important role in intracellular signal transduction and can induce and maintain the carcinogenicity of cancer cells. At this time, as an antioxidant, hydrogen has the potential to treat tumor diseases. Moreover, scientists have found that compared with other antioxidant substances, hydrogen can easily pass through the cell membrane and organelle membrane, reach the required parts for reduction reaction, and selectively remove oxygen free radicals. At the same time, because hydrogen itself is inactive, it will not cause physiological function damage and metabolic disorder.

　　Progress is rapid,

　　But the biological safety needs to be verified.

　　The effect of hydrogen on human health can be traced back to 1975. At that time, someone published a paper in Science magazine, saying that continuous breathing of 8 atmospheres of 97.5% hydrogen for 14 days, high-pressure hydrogen can effectively treat animal skin malignant tumors, and that this is the effect obtained through anti-oxidation.

　　In addition, in 2001, French diving doctors also proved that breathing 8 atmospheres of high-pressure hydrogen can also treat the inflammatory reaction caused by Schistosoma hepatica infection, which proved for the first time that hydrogen has anti-inflammatory effect, and proposed that the direct reaction between hydrogen and hydroxyl radicals is the basis for treating inflammatory injury.

　　However, the above research has not attracted widespread attention, mainly because high-pressure hydrogen is difficult to be used as a general clinical treatment.

　　It was not until 2007 that Professor Naruto Ota of Japan Medical University succeeded in the experiment of treating animal cerebral ischemia with 2% hydrogen, and it was published in the journal Nature Medicine, and "hydrogen therapy" finally attracted the attention of the whole world. 2007 is therefore recognized as the first year of "hydrogen medicine".

　　Since then, the research of hydrogen biology has begun to rise. The United States, Japan and China are the countries that have studied the medical biological effects of hydrogen the most, and each country has dozens of research institutions to participate.

　　In China, Sun Xuejun, a professor at Shanghai Second Military Medical University, is considered to be the first person to introduce hydrogen therapy, also known as "the first person in hydrogen medicine in China". Professor Sun Xuejun said that he has been engaged in gas effect research for a long time, but he didn’t start to study the medical effect of hydrogen until he saw the research results of Akio Ota in 2007, and gradually found that this therapy was really useful.

　　Nowadays, the research results of hydrogen biology in domestic medical circles are increasing. Take the number of topics related to "hydrogen medicine" included in China HowNet as an example. In 2007, the topics related to "hydrogen" were all related to energy. After 2007, a large number of papers on "hydrogen" and the medical effects of various diseases appeared, involving mental illness, heart disease, cancer and other fields. Some academicians also began to study "hydrogen medicine". Among them, Wang Hongyang, academician of China Academy of Engineering and director of National Hepatocellular Cancer Science Center, also led the research group to complete the Study of Hydrogen Therapy for Liver Injury, which was published in the internationally renowned Journal of Hepatology.

　　In 2014, Zhong Nanshan, an academician of China Academy of Engineering, discovered that hydrogen is effective for chronic obstructive pulmonary disease. In his speech at the World Thoracic Congress, he pointed out that "hydrogen molecules are mainly aimed at chronic diseases, and the most basic thing is the enhancement of antioxidant stress, not the simple repair, which is conducive to the recovery of the body. The concept is to treat the cause rather than the symptoms."

　　In March, 2014, the professional committee of hydrogen molecular biomedicine of China Medical Care International Exchange Promotion Association was also announced.

　　However, at present, "hydrogen medicine" is still in the basic and clinical research stage. Xu Kecheng told reporters that he hopes to collect as many clinical cases as possible through public welfare studios. Because some experts pointed out that although hydrogen has been found to be effective for many diseases, the biological mechanism of this effect still needs further study, and its clinical effect needs to be supported by sufficient evidence. For example, Dong Wenbin and Zheng Gaoli from the Institute of Pharmacology of Zhejiang Academy of Medical Sciences once wrote that the biological safety of hydrogen can not be fully proved at present, and many problems about hydrogen treatment need further study.

　　Key reminder:

　　Self-hydrogen therapy is not recommended.

　　At this point in the article, it is particularly worth reminding that the use of hydrogen to treat diseases should still be operated under the guidance of professional doctors, and it should never be used casually.

　　For example, the hydrogen used in hydrogen balloons is not recommended for treating diseases. In this regard, Lin Xinyong, president of Shanghai Shumei Medical Technology Co., Ltd. said that the gas normally inhaled by the human body must pass the safety tests such as toxicology and biocompatibility before it can be used. Even though water electrolysis can produce hydrogen, there are risks if the related equipment parts are non-medical grade.

　　Wei Youzhen, a professor at the Oriental Hospital affiliated to Tongji University, also said that the hydrogen used in hydrogen balloons is usually industrial hydrogen, and its source is not necessarily generated by water electrolysis. There may be other gases doped, so the purity is not enough, so it is not suitable for human inhalation, and it is not conducive to treating diseases.

Beijing, May 9 (Zuo Yukun), a client of Zhongxin. com, found that a total of 12 or 3 tea shops were opened in a small commercial street with a length of 200 to 300 meters in his hometown when he was shopping in Xiao Xu’s May Day holiday in a third-tier city.

"Can this really make money?" Xiao Xu is very confused.

In the face of such fierce industry competition, Xiao Xu feels that the brand may run out of the advantage through low-price strategy. However, after going to several stores, I found that the price increase of milk tea has become the mainstream.

Milk tea, what’s the matter?

New tea set off a "price hike"

Not long ago, the news that the beverage giant Coca-Cola announced the price increase made many "happy water lovers" feel that they would never be happy again, and also attracted many people to ridicule: "You can afford more than a dozen pieces of milk tea, but you still care about this three-dollar Coca-Cola?"

Nowadays, it seems that not only the price of three yuan of cola will increase, but also the price of more than a dozen pieces of milk tea will also want to flee.

Not long ago, there were many new Xia Rixin products on the brand of milk tea, and the prices of some home-made products were also refreshed. The prices of signature products such as Yangzhi Ganlu, Golden Coconut Oolong and 1L Fruit Tea were all raised in 2 yuan.

The prices of some products of CoCo Coco, a brand of milk tea, have also risen. The prices of Mo-flavored milk tea, Miss Hong Guo and Passion Fruit Double-Soup Gun have been raised by 1-3 yuan, and even the small ingredients have not been spared. The prices of pearls and coconuts have been raised from 1 yuan to 2 yuan, with an increase of 100%.

Earlier, "in order to continuously provide high-quality drinks and services, we will fine-tune the price of drinks on February 1, 2021." At the beginning of the year, many stores put out such notices and announced price increases.

The same price increase is also Yihetang, which previously focused on parity. In the past, the price of Standard Honey Snow Ice City has been rising all the way. The price of Yihe Roasted Milk, a signature product, has increased by one third from 6 yuan to 8 yuan.

The price of the same milk tea drink rose by two yuan.

Among the new tea brands with "10 yuan+"price band, the trend of price increase has already spread. This price band carries the largest share of milk tea consumers, and the game between quality and price may be between one and two yuan, which also makes them particularly sensitive to price.

"When I first started drinking CoCo, the original milk tea was only a cup of 4 yuan, and now the prices of new products it launched have begun to’ guarantee 20 for 30′." Some netizens recalled.

The sound of "rising" attracted a spit. "What about the current tea shop? The price of the old one is one or two yuan, and the new one is directly above 20 yuan. My economic ability can’t keep up with the price increase of milk tea." Some consumers concluded.

The price increase is only because the milk tea cup is expensive?

What is the reason for the price increase? A "Letter to Tea Powder" sent by Wang Xiaolong, the founder of Chabaidao, was circulated on the Internet, which mentioned that due to the influence of the environment, the prices of raw materials such as fruit equipment and packaging rose, and the price of drinks would be fine-tuned.

Generally speaking, just as the CEO of Coca-Cola Company attributed the brewing price increase to the rising price of raw materials, the reason for this wave of price increase of milk tea is that the wind of rising commodity prices has blown from the upstream raw material supply chain to the milk tea cups of every consumer.

"The ups and downs of the price of a single raw material are normal, every year, but it is the first time that so many raw materials have risen together." Some people in the tea industry told the media.

Not long ago, Ms. Liang joined a chain tea shop. She told Zhongxin. com that it was still quite difficult to apply for joining this first-line tea brand. In addition to the registration, preliminary examination, interview and training in the process, before the store opened, Ms. Liang had invested nearly 600,000 yuan.

But what worries Ms. Liang is still behind.

"I chose to join this milk tea brand because I liked it before, drank it often, and felt that it was cost-effective. So I was shocked when I received the new menu. Why did my price increase when I opened this business? " Ms. Liang said, "But when I really started to do business, I found that the costs of all links are indeed rising."

The first is the raw material end. Ms. Liang takes the fruit perfume lemon as an example: perfume lemon has become a common raw material for fruit tea because of its lower acidity than ordinary lemon. Since this year, the price has soared by more than four times. "In previous years, the purchase price of almost 4 kg in 5 yuan has now risen above 20 yuan."

There are two main reasons for the price increase of perfume lemon: first, some areas of Guangdong, its main producing area, are affected by the climate, and the output is lower than in previous years; Second, there is a "Southeast Asian wind" in the new tea industry this year. A variety of lemon teas are popular, and the demand for perfume lemons is higher than in previous years. The price rises under the contradiction between supply and demand.

At the same time, due to the influence of international trade, some fruits with relatively high imports, such as grapefruit and pineapple, have also seen quite obvious price increases. "I am counting on the summer, and a large number of fruits such as watermelons are on the market. After the price comes down, the cost of raw materials can be pulled down." Ms. Liang said.

In addition to fruit raw materials, there are many "invisible" parts of consumers that are also experiencing price turmoil.

For example, after the Spring Festival this year, the prices of copper, stainless steel, aluminum and other metals have risen in turn, which has affected the pricing of various tea-making equipment such as sealing machines and smoothies; The price increase of plastic particles, paper, PE film, etc., has a few cents of cost floating on each milk tea cup; The cost of raw materials such as seemingly inconspicuous leaflets, take-away packaging bags, corrugated cup holders, etc. has increased by several thousand yuan per ton, which adds up to the same amount.

Ms. Liang also mentioned that the "plastic ban on straws" that began on New Year’s Day this year also made many milk tea shopkeepers "feel a pain in their hearts". At the beginning, tea shops basically changed into paper straws with relatively low cost, but they got a bad review because of the disadvantages of not being able to open and often soaking. Later, most head brands were replaced with PLA straws.

"The cost of each PLA straw is about a dime more expensive than that of plastic straws and a few cents more expensive than paper straws. On average, the store consumes hundreds of straws every day, which is still very heartbreaking. " Ms. Liang said.

Competition intensifies, can the new tea bear it?

"If the milk tea that was originally ten dollars rose to twenty, why didn’t I add a few more dollars to buy hi tea directly?" In the consumer’s feedback on the price increase, "Do you have any points in your milk tea" is the loudest.

Practitioners also said that the impact of this price increase on brands in the price band above 20 yuan is not so great, and the biggest impact is on regional small brands. "They sell about 10 pieces of fruit per cup, and their gross profit is not high and their ability to resist risks is weak."

Consumers line up to buy milk tea. Zhongxin. com Zuo Yukun photo

"I think for our store owners, even more than consumers, we don’t want to raise prices." Ms. Liang said that the price increase may be a matter of buying or not buying in another store for consumers, but for new tea brands with fierce competition, the price increase of one or two yuan may mean sending the hard-earned consumer groups to competitors.

Since the development of new-style tea, fresh fruit, high-quality tea and fresh milk have become "standard". The price of "genuine materials" is that the industry has long since lost its initial profiteering, and it is even said that the net profit of new-style tea is only 10%. When all aspects of costs are rising, small brands that have to rely on price increases to maintain costs also lose their low-price advantage.

In the eyes of the industry, low-priced brands may usher in a reshuffle.

Milk tea brands are making waves in the tide of price increase, which one would you choose? (End)

1905 movie network news The Sino-French co-produced film, which was supervised by luc besson, has been registered in major cinemas in China on November 8th. The film was produced and written by Qiao Wei, directed by An Jianjun and Yang Huilong, and produced by Liu Yongsheng. French movie stars Vanessa Guide and Juliet Besson joined hands with domestic powerful actors Liu Peiqi, He Zhengjun, Du Xudong, Cao Yutong, Ding Jiali and Cao Li. The film has won the best feature film and the best China film recommended by the Spanish Sebastian Film Festival.

The audience calls for the era of high-quality film recording.

The film betrothal tells the story of a French female journalist, Si Nuo, who happened to come to China in the early 1980s after the reform and opening-up, and met a rural guy, Liu Changgen, and they had a wonderful time together. Si Nuo recorded what he saw and heard with his camera, witnessed the process of young people’s love and marriage entanglement in China at that time, and left an unforgettable romantic love story with Changgen.

After the film was released, it received rave reviews on major social media platforms. The audience said in succession that "the chronological films of Sino-French cooperation are full of pure love and beauty, without material infiltration, only the perfect pursuit of spirit. Chinese and Western young people are handsome and handsome, and the senior old drama bones are deductive. Each role is unique and has the brand of that era, which is true and natural. " "My favorite screenwriter Qiao Wei and directors An Jianjun and Yang Huilong jointly created the works, and I also invited my favorite foreign director luc besson to supervise the production. The effect really didn’t disappoint me, which is probably the greatest happiness for fans." "The long-awaited film of Qiao Wei and An Jianjun working with Luc Besson has finally been released! A film that has a sense of the times, a wonderful storyline, a powerful old-fashioned interpretation, and many simple and sincere unsung heroes have carefully created an international award. I really love it, and I believe everyone does not want to miss it! " "The era of reform and opening up is memorable. The love story of this impetuous era is very meaningful. Sino-French cooperation is really amazing! Looking forward to the new work! " The film betrothal was recognized by many audiences on its first day of release, which shows that the quality of the film is really good.

A bold attempt of co-production between China and France: a new chapter in international cultural exchange

The film betrothal was recognized by the audience on the first day of its release, which is not only due to the quality of the film, but also related to the friendly exchanges between China and France. The film was produced by the famous French director luc besson. He has been in film for 36 years, and has directed such famous films as Blue Sea and Blue Sky and sci-fi action movies.

As a world-renowned director, luc besson not only personally produced this film, but also provided his own manor as the French shooting location of this film. In addition, luc besson introduced Europa, an old French film company, to participate in the production, partnered with the first-class domestic production team, and personally received the crew when they went to France to shoot, which can be said to provide strong support for the final high-quality completion of the film. The French people, represented by Luc Besson, and the French people, represented by Qiao Wei and An Jianjun, bear the mission of establishing friendly diplomatic relations between the Chinese and French peoples.

As an important bridge of cultural exchange between countries, film plays an important role.The Chinese-French co-production film betrothal is also deeply in the hearts of the people. It is worth mentioning that the film profoundly expounds the historical changes in China’s reform and opening up and the rural areas, and shows the course and style of rural changes in China and the progress and awakening of people’s consciousness. On the other hand, it reflects the changes of the times, the impact of culture and the progress of society. It is also an opportunity for the broad masses of people to review and summarize after their hard work. From this perspective, betrothal is undoubtedly a film with great times value, which can give us the courage and motivation to continue to deepen reform. At the same time, it also serves as a cornerstone of the bridge between Chinese and French cultures, so that ordinary audiences can find the meaning and direction of their lives through watching movies. It is really worth walking into the cinema at this time to feel immersed.

Rene Liu’s left knee was injured in a car accident. (data map)

　　Rene Liu hasn’t been free since the "Sleepwalking" concert, so she hurried to pay off her debts. Fortunately, before the Lunar New Year, she had peace of mind to have knee surgery. Even though her schedule was busy, she wrote calligraphy and painted oil paintings in stages and posted them to fans.

　　After the concert of Little Dome on November 29th, Rene Liu didn’t rush to rest first, but continued to catch up with his trip. He often ran to the mainland for three or four days, went back to Taiwan Province to rest for one day, and then went out for three or four days. For example, the day before yesterday (December 28th), he finished singing a campus concert at the university, and immediately flew to the mainland to work yesterday. He only hoped to settle his work and have an operation with peace of mind.

　　Rene Liu’s left knee was injured in a car accident, and the old injury recurred due to years of busy filming, and her right foot was also injured by improper application of force. She has arranged to have a knife operation before the end of January, so that she can take advantage of the leisure February to have a good rest and spend the New Year with her family.

　　Hualong. com-Chongqing Business Daily reported on February 19th.On the 16th of this month, the netizen "Tofu" posted in Dayu Bar that "the poor panda is extremely dirty" in Chongqing Zoo. After this post was sent out, it attracted the strong attention of thousands of netizens. Yesterday, the netizen "Happy" also took out the pandas in foreign zoos for comparison, saying that "they are all national treasures, and they are sloppy in Chongqing".

　　Netizen posts

　　Panda looks very untidy.

　　Netizen "Tofu" posted that in people’s minds, the national treasure giant panda is a symbol of preciousness and holiness, but several giant pandas in Chongqing Zoo look sluggish and dirty, and their living environment is also shabby, just like "beggars". The netizen "Happy" posted that the living environment of pandas in some zoos in other places is very good, and the pandas are also chubby and very cute, but the pandas in Chongqing Zoo are covered in mud and look very sloppy.

　　Journalist investigation

　　Pandas often take a bath and catch a cold.

　　Yin Yuzhong, deputy director of Chongqing Zoo in charge of animal conservation, explained that wild giant pandas generally live in high-altitude areas with clean air and no wet soil above 2000 meters above sea level, so the giant pandas there are clean and abnormal. However, the air humidity in Chongqing Zoo is high, and the mud is wet for a long time. Giant pandas often sit and even roll on the mud, and their fur is dirty with mud or feces.

　　He said that the giant pandas in the zoo take a bath regularly, usually once a month in winter, and several times a month in summer, and sometimes they have to clean their fur with shampoo. If you take a bath every day, it is easy for the giant panda to catch a cold. The bathing cycle depends on the physiological condition of the giant panda.

　　The giant panda is old.

　　Yin Yuzhong said that the giant panda looks depressed because several giant pandas kept in Chongqing Zoo are older and can’t be as energetic as young pandas. Moreover, because of coming to Chongqing from high altitude, the environment has changed greatly. "Pandas have a long process of adaptation, and in this process, their state will also be affected." Yin Yuzhong said that each giant panda produces an average of 30 kilograms of feces every day, which is the result of giant pandas eating more than 75 kilograms of bamboo shoots and leaves. To this end, managers collect and weigh the feces of giant pandas every day.

　　Netizens questioned

　　Noise is harmful to the health of animals.

　　Explanation: put an end to all noise during animal breeding.

　　Netizen "Tofu" said that there is noise around the zoo, and there are people yelling in the park. Will the noise have an impact on animals?

　　Yin Yuzhong said that there is indeed noise interference. Inside the new gate of the zoo, there is a large playground, which is mainly for children who come to the zoo to play, and noise is accompanied. The zoo has been working for amusement park operators to reduce noise as much as possible. During the period of animal breeding, it is required to put an end to noise so as not to scare the animals.

　　Why is the tiger so thin?

　　Explanation: The tiger belongs to the South China tiger, with a slender figure.

　　Netizen "Later" said, is the tiger not full? As thin as skin and bones.

　　Yin Yuzhong explained that the zoo needs more than 2 million yuan for feeding these treasures every year. For example, tigers only need to eat 6 kilograms of meat every day, not including a certain number of chicken skeletons. In summer, tigers eat 8 kilograms of meat every day. Some tigers look thin, in fact, because they belong to the South China tiger and are slender.

　　Expert reminder

　　Don’t feed animals.

　　The reporter found that although warning signs prohibiting feeding animals are hung on the partition wall of each animal partition, there are still many tourists throwing popcorn, biscuits and other foods at giant pandas and monkeys. Yin Yuzhong hopes to appeal to tourists through this newspaper not to throw food at animals again. He said that every animal in the zoo has its own eating habits. Tourists throwing food at random will disturb their eating habits, thus endangering their health.

　　CCTV News:From 8: 00 am yesterday (5th), the aircraft wake reclassification experiment was started in Guangzhou and Shenzhen. The wake generated in the air when an airplane flies is like the waves and eddies caused by a ship sailing in the water, so two airplanes must keep a safe distance in the air.

　　In order to prevent dangerous situations such as pitching, rolling and stall caused by the aircraft behind entering the vortex field at the front tail, ICAO has formulated wake interval standards based on practical experience.

　　The scheme of this experiment comprehensively studies the remarkable characteristics of domestic large-scale hub airports, such as aircraft types and distribution periods, and subdivides heavy and medium-sized aircraft.

　　From 8: 00 a.m., the aircraft participating in the test in Guangzhou and Shenzhen control areas began to fly according to the new safety interval standard. At 8: 05, the interval between Boeing 757 and Airbus A320 was reduced from 9.3 km to 6 km.

　　Kang Nan, Vice Minister of Air Traffic Control Department of Air Traffic Control Bureau of Civil Aviation Administration:With reference to relevant foreign standards and operating experience, and in combination with the actual operating characteristics and distribution characteristics of China civil aviation, we have studied and formulated the wake interval standard of China.

　　Taking Airbus A380, a super heavy aircraft, and Boeing 777, as examples, the wake interval between the front and rear aircraft was reduced from 11.1km to 9.3km, with an optimization range of 16.2%. However, the distance between light aircraft, medium-sized aircraft and heavy aircraft increased by 4.3km and 5.1km respectively, with an increase of more than 45%, and the possibility of being affected by the wake of the preceding aircraft was further reduced.

　　The experiment of aircraft wake reclassification will be conducted at Guangzhou Baiyun Airport and Shenzhen Baoan Airport and their control areas for one year. The first stage is the testing stage, in which China Southern Airlines, Hainan Airlines, Shenzhen Airlines, FedEx and United Parcel Service Company are arranged to participate. The second stage is the promotion stage. On the basis of summarizing the operation experience in the first stage, the wake reclassification method and separation standard are applied to all applicable aircraft operating in Guangzhou and Shenzhen airports.

　　It is estimated that the experiment of aircraft wake reclassification will improve the runway capacity and operational efficiency of civil aviation.

　　The runway capacity is expected to increase by 5% during peak hours, which can effectively alleviate the situation of route congestion, and passengers’ travel efficiency and experience will be further improved.

　　Since 2010, the average annual growth rate of China’s civil aviation flight volume is 11.6%, but the average annual growth rate of civil aviation fixed routes is only 1.7%. At present, there are usually about 400 flights a day on busy international routes, while there are 13 routes with more than 500 flights a day in China.

　　Kang Nan, Vice Minister of Air Traffic Control Department of Air Traffic Control Bureau of Civil Aviation Administration:The current ICAO wake separation standard was formed in the 1970s of last century, which limited the improvement of the capacity and efficiency of our large busy airports to some extent, and also caused unnecessary flight delays and waiting.

　　According to the calculation of the air traffic control department, the annual runway capacity of the top 10 busiest airports in China is expected to increase by about 47,450 flights, the annual runway capacity of Beijing Capital Airport is expected to increase by about 7,665 flights, and the annual runway capacity of the two airports in Shanghai is expected to increase by about 9,490 flights.

　　Beijing, June 15 (Reporter Shangguan Yun) "Has the craze for science fiction literature come?" In fact, I am not so optimistic. " Recently, Chen Qiufan, a science fiction writer, put forward the above views when interviewed by a reporter from Zhongxin.com (WeChat WeChat official account: cns2012).

　　Not long ago, his short story "Fear Machine" was shortlisted for the 10th Global Chinese Science Fiction Xingyun Award, along with works by writers such as Liu Cixin and Liang Qingsan.

　　Love reading science fiction has been rejected.

　　Like science fiction, Chen Qiufan has been interested since he was a child.

　　"I read science fiction when I was in kindergarten, but I can only read simple plots, and some contents are not very understandable." He remembers reading a series of classic works by Verne and Wells, which "felt like entering a particularly magical world".

　　When he was in junior high school, he tried to write some science fiction novels and then contributed them everywhere. At the age of 15, he sent the novel Bait to the competition and won the prize successfully. When the certificate was sent to the school, it was handed over by the class teacher. Chen Qiufan still remembers the students’ surprise at that time.

　　However, his writing career didn’t start there: after winning the prize, another novel was rejected, which made Chen Qiufan feel somewhat depressed. In addition, to prepare for the college entrance examination, in about two years, he pressed the "pause button" of writing.

　　"I tried to pick up my writing after I was admitted to Peking University. At that time, I took the path of pure literature. " But write to write, those articles can’t satisfy Chen Qiufan, "always feel not attractive enough. So I changed it to writing science fiction. "

　　Since then, he has published sci-fi works such as Fish in Lijiang and Year of the Rat, and won the Global Chinese Science Fiction Nebula for nine times. The Ghost Trio has also been included in the sci-fi anthology "Future People Don’t Exist".

　　It is not easy to add "hard science fiction" elements to novels.

　　Talking about his own creation, Chen Qiufan thinks that the more difficult thing is the combination with scientific and technological elements, that is, the "hard science fiction" elements that people often say.

　　"Not as long as ‘ Have a brain hole ’ You will be able to write good science fiction. " Chen Qiufan explained that when writing, science fiction writers also need to know the most advanced science and technology and scientific facts, and the novels will look better.

　　He feels that if there is an opportunity, science fiction writers can communicate with scientists who work in the front line. "Scientists know the most cutting-edge technology, and writers have a big brain hole. If the two are combined, there may be good results."

　　However, sometimes, some misunderstandings will make Chen Qiufan feel a little helpless. He said that some readers will confuse science fiction with popular science works to varying degrees. "The latter should be particularly accurate about all kinds of knowledge and not allow fiction; The former is still full of literary color, and the two are not the same. "

　　"The fields involved in science fiction literature are not narrow, not just aerospace, space and so on." Chen Qiufan said that it also includes anthropology, ethics and other disciplines. "For example, in The Wandering Earth, when people discuss whether it is feasible to put an engine on the earth, they also think about ecological environment protection and human ethics.".

　　Science fiction literature craze has come? may not

　　After writing science fiction for many years, Chen Qiufan has a deep understanding of the "minority" situation of this literary type: the number of writers is relatively small, and the audience is also small.

　　However, with Liu Cixin winning the Hugo Award in 2015 and the sci-fi movie The Wandering Earth showing in early 2019, this situation seems to be slowly changing. Especially after the The Wandering Earth fire, many people think that "science fiction literature fever" has come.

　　"It seems that science fiction has become a slogan, capital, IP… … A lot of people poured in at once. The film has a relatively wide audience, and The Wandering Earth’s popularity has indeed opened up a more popular market. " Chen Qiufan does not deny that people’s attention to science fiction literature has increased, but he thinks this is not enough to be blindly optimistic.

　　He gave a good reason: "The well-known sci-fi writers such as Hao Jingfang and Liu Cixin won the grand prize, and more people don’t know much about writers like me and Han Song;" There are still few publishing channels for young writers’ works in the traditional sense, and it is difficult to get ahead. "

　　"For example, Mo Yan’s teacher won Nobel Prize in Literature, and his novels are very popular, but the sales of other pure literature writers are good? No. " Chen Qiufan said that at present, the situation of science fiction literature is similar, and the publishing market only prefers great writers who can guarantee a certain sales volume, "said ‘ Science fiction literature craze ’ Come, in fact, not necessarily. "
