There is always a touch, secret and great!

There is always a feeling, endless!

Yesterday, alumni donated 78 million anonymously.

Brushed the circle of friends of Wu Daren.

The topic quickly rushed to the hot search.

This 78 million donation comes from

An anonymous alumnus from School of Life Sciences, Wuhan University

Out of gratitude for the care and training of Wuhan University.

Decided to turn their scientific and technological achievements into income.

Donate anonymously to your alma mater.

At the same time, in the name of teacher Yu Xianjue,

Name the donation project as

"Yu Xianjue Life Science Education Fund"

Who is Mr. Yu Xianjue?

Why is the 78 million donation named after him?

With Luo Luo Jia Jia

Find the answer to the story.

Yu Xianjue, Professor of School of Life Sciences, Wuhan University. People from Changsha, Hunan. Graduated from biology department of Wuhan University in 1935. In 1949, he received a doctorate in philosophy from California Institute of Technology. After returning to China, he served as a professor at Wuhan University, director of the Department of Genetics of the Department of Biology, and the first and second directors of the Hubei Genetic Society. Member of China Democratic League. Since 1980, the karyotype of freshwater fish has been studied and achieved results. Editor-in-chief of Genetics, and author of papers such as Studies on Chromosomes of Freshwater Fish in China.

In November 1909, Yu Xianjue was born in a peasant family in Changsha County, Hunan Province. My parents make a living by farming and have eight children, and Yu Xianjue ranks third. Because of his poor family, his parents had to adopt one of his brothers to his uncle who was in business. And my brother provided him with a lot of financial assistance for his later schooling. Yu Xianjue grew up in such a typical southern rural family, studied hard, made progress and was strong since childhood, and had a strong love for nature and biology.

In 1931, he was admitted to the Biology Department of National Wuhan University with honors. During his college years, he not only got excellent grades, but also loved sports. When he graduated in 1935, he was recommended by Professor Zhang Yingwu, an embryologist, to stay in school as a teaching assistant in the Department of Biology.

Ten years after his graduation, during the period of War of Resistance against Japanese Aggression, he moved to Leshan, Sichuan with Wuhan University. During the hard war years, he not only didn’t lose his major, but also studied hard, worked hard, compiled his own handouts, and enriched his theoretical knowledge in the teaching practice of histology, cytology and embryology. In the second year after the victory of the Anti-Japanese War, Yu Xianjue was funded by the Lee Foundation and was sent to the Biology Department of California Institute of Technology to study for a doctorate. Yu Xianjue entered Morgan’s laboratory at California Institute of Technology and became a student of Professor Sturtevant.

Mendel made a pioneering contribution to establishing the basic principles of genetics. Morgan and his students used Drosophila as materials to discover the laws of sex-linked inheritance, linkage, exchange and non-segregation, and put forward the theory of genes, which is a significant development of Mendel’s theory of genetics and laid the foundation for the development of modern genetics. Professor Yu Xianjue is a modern geneticist who grew up in Morgan’s laboratory during this period.

At that time, Morgan, the founder of the biology department of the school, had just passed away, and Morgan’s eldest disciples, Sturtevant and Mrs. Morgan, continued to study fruit flies in Morgan’s laboratory. Sturtevant received his doctorate from the Drosophila Laboratory in Morgan, Columbia University in 1910, and then came to California Institute of Technology with Morgan. Sturtevant students E. B. Lewis and E. Novitski gave Yu Xianjue direct guidance in experimental research. Lewis later became an academician of the American Academy of Sciences, and won the Nobel Prize in 1995 for his achievements in developmental biology of Drosophila.

Four China scientists of the older generation have studied in this laboratory, namely Li Ruqi, Tan Jiazhen, Lu Huilin and Yu Xianjue. Yu Xianjue completed his research work during his doctoral period in 1949, wrote a 112-page doctoral thesis, successfully passed the doctoral thesis defense, and obtained his doctorate.

Yu Xianjue’s doctoral thesis is to study the reverse mutation and position effect of Drosophila by X- ray technology, and his tutor and Lewis are very satisfied with his experimental results. Yu Xianjue made a series of new discoveries, including the famous antenna foot mutation in modern genetics textbooks. This Drosophila mutant named AntpYu was recommended by Lewis and incorporated into the genetic variations of Drosophila melanogaster, and published by Carnegie Institute in 1968. The discovery of this mutant laid a foundation for Lewis and others to study homeobox genes and the development of Drosophila. Also included in the book is T (2; 3)AntpYu mutation, B48g, Scar, T (2; 3)B48g and t (2; 3) Scar mutation, etc.

Yu Xianjue is very patriotic. After receiving his doctor’s degree, he decided to go back to China and devote himself to the construction of new China. At that time, his brother was the Consul General of the National Government in Houston, and repeatedly advised him to stay in the United States, but Yu Xianjue’s determination to return to China never wavered. The journey to "go home" was hard. He knew that the motherland lacked professional books, and brought back a large number of professional books and documents with him. When he returned to Tianjin to go ashore, it coincided with the establishment of New China on October 1, 1949. After several rounds of rolling, he returned to Wuhan and once again devoted himself to Luojiashan as a professor in the Department of Biology of Wuhan University. Yu Xianjue has taught in the Biology Department of Wuhan University for more than 50 years.

Letter from Hu Shengchu as a Professor of Science College

Yu Xianjue is a loyal Morgan scholar. Since the 1960s, with the acceptance of Morgan School in the whole country, he selected fish as materials for genetic experiments and enrolled graduate students. However, it was soon devastated by another decade, and the newly established genetics laboratory had to be terminated. It was not until the end of the Cultural Revolution in 1978 that he resumed recruiting graduate students and conducting genetic research.

The Chinese Genetic Society was established in 1979, and Professor Yu Xianjue was elected as the first director of the Chinese Genetic Society and the first editorial board of the Journal of Genetics. In the same year, Yu Xianjue advocated the establishment of Hubei Genetic Society, and served as the chairman of the Society for four consecutive years, making great contributions to the development of genetics in Hubei Province. In 1980, he was elected as the first director of China Society of Cell Biology. After the National Science Conference in 1978, he compiled the outline of "Introduction to Genetic Engineering" and made a report to Hubei provincial authorities, Wuhan University and other universities, which played an important role in publicizing Mendel’s genetic theory and popularizing genetic knowledge.

He and graduate students have conducted extensive research on cytogenetics of freshwater fishes in China, and obtained the first-hand information on cytogenetics of freshwater fishes in China, which is the first systematic study on chromosomes of freshwater fishes in China in China. The research achievement "Study on the Karyotype of Freshwater Fish in China" won the second prize of the Science and Technology Progress Award of the State Education Commission in 1988, and was edited by Yu Xianjue and published in Science Press in 1989. This book has become a reference book in the field of fish genetics research.

On the basis of these studies, he further studied the fine structure and genome of fish chromosomes, and the research result "Study on the Fine Structure and Genome Structure of Fish Chromosomes" won the second prize of the Science and Technology Progress Award of the State Education Commission in 1995.

Yu Xianjue’s granddaughter Yu Li said that Grandpa’s students have always been in contact with their families, and this anonymous donation by alumni was also directly contacted with her. She felt very surprised and very moved. "My mother and I have advised before, but the alumni said that this is their long-cherished wish for many years."

Following Yu Xianjue’s footsteps, Yu Li has also been teaching in the College of Life Sciences. She grew up beside her grandfather. At that time, she didn’t know much about her grandfather’s work. She just felt that other people’s grandfathers seemed to have time to play with their grandchildren every day, but her grandfather was very busy all day long. Occasionally, she would take her to make gecko specimens or climb Luojia Mountain to plant small plants when she was free. I didn’t understand until I grew up. Influenced by the Cultural Revolution, Grandpa, as a modern geneticist who grew up in Morgan’s laboratory, had interrupted his academic research countless times, so once he returned to his scientific research post, he devoted himself to his work with double enthusiasm and energy.

In her memory, there were always students coming and going at home, some came to ask grandpa academic questions, some came to report the progress of the experiment, and grandpa was always cheerful and equal and gentle to the students. If he was still talking about work at dinner time, he would ask his mother to serve a bowl of noodles covered with eggs and continue to discuss the problems with the students while entertaining. At that time, a bowl of egg noodles could be said to be quite good food.

▲ In the 1960s, Yu Xianjue was instructing graduate students.

Yu Xianjue was honest and broad-minded all his life. Peace of mind and noble character; Life is simple, honest and simple; Strict scholarship and profound knowledge; Good teaching and tireless teaching. He has successively directed cytology experiments and embryology experiments, and taught courses such as histology, cytology, genetics, zoology, entomology, introduction to biology, agriculture and livestock breeding and cytogenetics.

His teaching preparation is well-prepared, his lecture language is accurate, his concept is clear and his logic is strong. He always said, "If you don’t memorize in advance and think about what to say temporarily, it’s easy to digress and make mistakes." His teaching has been well received by teachers and students in the Department of Biology.

Yu Xianjue attached great importance to discipline construction and personnel training, and established the doctoral program of genetics in Wuhan University, which was also the second batch of doctoral programs in China at that time. Now it is a national key discipline and a comprehensive genetic research institution and personnel training base with complete research directions in plant genetics, animal and human genetics and microbial genetics. Professor Zhu Yingguo, an academician of China Academy of Engineering, and professors Yu Qixing, Song Yunchun, Zhou Gang, He Guangcun, Yang Daichang, Hu Zhongli, Li Lijia and Li Yangsheng all grew up in this doctoral program. In his later years, he enrolled the only postdoctoral fellow, Zhou Rongjia, and later became a professor in the department.

"This alumnus who donated anonymously is my senior. I am also very excited to hear about this charity. He is definitely influenced by Teacher Yu. This is a typical student of Teacher Yu!" Zhou Rongjia said. In 1992, Zhou Rongjia entered Wuhan University to engage in postdoctoral research with Yu Xianjue. At that time, Yu Xianjue, who was over 80 years old, was in poor health, but he still talked with Zhou Rongjia specifically and told him to be a good person before doing scientific research.

"This sentence has a great influence on me," Zhou Rongjia remembers vividly. At that time, the conditions of the postdoctoral mobile station were very difficult, and many studies were almost started from scratch. Yu Xianjue gave Zhou Rongjia great autonomy and allowed him to play freely within the framework of fish genetics. "The old man was very low-key, but he did very well academically. He said that being a man must have a pioneering spirit, which has had a profound impact on my academic path. "

Diagnostic criteria for hypertension have changed! Many people already have high blood pressure, but they don’t know it yet!

Wake up one night, many people have high blood pressure? Blood pressure ≥140/90 mm Hg has been the diagnostic standard of hypertension.

On November 13th, the Clinical Practice Guide of Hypertension in China was issued, which lowered the diagnostic criteria of hypertension in adults and changed the original 140/90 mm Hg to ≥130/80 mm Hg.

After the standard was lowered, many people who were at the previous critical value became hypertensive!

Why did the diagnostic criteria of hypertension change?

Professor Zhao Dong, director of the Epidemiology Research Office of anzhen hospital, Beijing, introduced at the online press conference on November 13th, "The guideline revised the diagnostic standard of hypertension to ≥ 130/80mmhg, which is not only supported by sufficient international and domestic evidence-based medical evidence, but also the people with blood pressure levels of 130-139mmhg and/or 80-89mmhg are mostly young and middle-aged. Lowering the diagnostic standard reflects the concept of moving forward the defense line and strengthening the initial prevention, otherwise we will miss reducing hypertension.^①

What about people with blood pressure of 130/80~140/90?

The diagnostic threshold of adult hypertension has been lowered from 140/90 mm Hg to 130/80 mm Hg, which means that some people suddenly become hypertensive. According to the new standard, it is estimated that there will be more than 600 million adult hypertensive patients in China, compared with the previous estimate of 245 million.

"I think (after the implementation of the new standard) more young and middle-aged patients may be diagnosed." Hu Dayi, chief physician of Cardiovascular Department of Peking University People’s Hospital, was interviewed by national business daily on November 13th. At present, there are many young patients with hypertension in China, and the unhealthy lifestyles associated with it include lack of exercise, heavy drinking, unhealthy diet and obesity.^②

However, Professor Hu Dayi said that for young and middle-aged patients with hypertension whose blood pressure is between 130/80mmhg and 140/90mmhg, it is suggested that drugs should not be used immediately, but five prescriptions that can effectively control hypertension should be adopted, namely, drug prescription, exercise prescription, nutrition prescription, mental, psychological and sleep prescription, and smoking cessation and alcohol restriction prescription.^②

Guo Yifang, vice president of Hebei Provincial People’s Hospital, said in an interview with 21st century business herald on November 13th that although it is predicted that there will be 600 million more patients, only 22% of them need medication, and most of them don’t need medication. Only through active lifestyle intervention, blood pressure can be restored to the ideal range, such as controlling diet, losing weight and gaining muscle, eating less salt and quitting smoking and drinking.^③

The new guidelines recommend that patients with high cardiovascular risk actively start antihypertensive drug therapy, and patients with low cardiovascular risk can undergo lifestyle intervention for 3-6 months. If blood pressure is still not up to standard, antihypertensive drug therapy can be started.^④

Manage high blood pressure, and the new guide gives these practical suggestions!

The new edition of "Guidelines for Clinical Practice of Hypertension in China" has made important adjustments to the antihypertensive targets of different groups of people, and we have summarized seven points that everyone is concerned about:

1. Insist on blood pressure monitoring.

Rest quietly for 3-5 minutes before measuring blood pressure. Avoid strenuous exercise, drinking alcohol, drinking caffeinated drinks and smoking 30 minutes before taking blood pressure.

When measuring, sit in a chair with a backrest, put your feet flat on the ground and don’t cross your legs. The upper arm is flat on the desktop, and the center of the cuff of the sphygmomanometer is kept at the same level as the heart.

When measuring blood pressure for the first time, the blood pressure of both upper arms should be measured, whichever side is higher.

It is recommended to measure blood pressure once every morning and once every night. For patients with hypertension, it is recommended to measure blood pressure before taking medicine, before breakfast and after emptying bladder in the morning. It is recommended to measure blood pressure before dinner at night, and within 1 hour before going to bed when conditions do not permit.

Take at least two consecutive blood pressure readings for each measurement, with an interval of 1-2 minutes, and take the average of the two readings. If the difference between the first and second blood pressure readings is greater than 10mmhg, it is recommended to take the third measurement and take the average of the last two readings.^④

2. Replace common salt with low sodium salt.

The guideline points out that excessive sodium intake and insufficient potassium intake are one of the important risk factors for hypertension.

Less sodium: it is recommended that the daily salt intake of each person should not exceed 5 grams, and low sodium salt can be used. The results of SSaSS research based on Chinese people show that compared with common salt, the risk of stroke, major cardiovascular risk and all-cause death in the low-sodium salt replacement group (about 75% sodium chloride and 25% potassium chloride) decreased by 14%, 13% and 12%, respectively.

Potassium: Pay attention to eating more foods rich in potassium, including fresh fruits and vegetables, low-fat dairy products, nuts and bean products.^④

Table from Dietary Guidelines for China Residents 2016^⑤

3. Try the DASH diet mode.

DASH diet is a dietary pattern designed for hypertension, the core of which is high calcium, high potassium, high magnesium and high dietary fiber, limiting saturated fatty acids, ensuring rich unsaturated fatty acids, limiting sugary drinks and sweets and reducing salt intake.

Li Haiyan, the chief nurse of Cardiovascular Department of PLA General Hospital, suggested in the Health Times in July 2021 that for Chinese people, the dietary pattern of hypertension could be used for reference. In the diet:

Cereals can be whole wheat pasta, oats and brown rice, and excellent rice flour, cakes, sweets and fried foods can be reduced or avoided;

Meat can be lean pork, beef and mutton, peeled poultry (chickens, ducks and geese), fish (deep-sea fish, such as salmon), shrimp and eggs.

Eat fruit instead of processing it into juice or drinking candy-flavored drinks;

Vegetables can be seasonal vegetables such as spinach, celery, oily wheat and cabbage;

Dairy products can be fat-free or defatted, low-fat dairy products;

Pay attention to calories when eating nuts, and choose small portions and salt-free ones;

Oils can be rapeseed oil, olive oil and corn oil to reduce or avoid the intake of lard, cream and butter.^⑥

4. Do aerobic exercise for at least 30 minutes every day.

The new guidelines recommend that hypertensive patients with blood pressure less than 160/100mmhg should take moderate or high-intensity aerobic exercise for 30-60min every 5-7 days a week, and do resistance strength exercises 2-3 times a week.

Moderate intensity aerobic exercise:

30-60 minutes/day, 5-7 days/week, reaching 50%-70% of the maximum heart rate.

Such as cycling, swimming, walking, running, badminton, table tennis, aerobics, group sports and other aerobic sports.

In addition, Tai Chi and Qigong can also help lower blood pressure.

Resistance strength exercise:

90-150 minutes/week, 50%-80% of the maximum load at one time, 6 exercises/group, 3 groups, 10 repetitions.

Such as dumbbells, sandbags and elastic belt.

Equidistant grip strength training:

2 minutes each time, 4 times in total, with an interval of 1 minute each time, 3 days a week.

Attention should be paid to avoid bowing your head and holding your breath during exercise. Patients with hypertension who cannot complete the recommended amount due to physical reasons should increase all kinds of physical activities as much as possible according to their own conditions.

Previously, Europe issued a consensus document on personalized exercise prescription for the prevention and treatment of hypertension. The consensus recommended aerobic exercise as a first-line physical activity for patients with hypertension, which can help reduce the average systolic blood pressure by 4.9-12.0 mm Hg and the diastolic blood pressure by 3.4-5.8 mm Hg.^⑦

5. Control your weight and waistline.

The guidelines point out that overweight and obesity are important risk factors for hypertension. The best goal is to reach the ideal weight, the body mass index is 18.5-23.9 kg/m2, and the waist circumference is controlled to less than 90 cm for men and less than 80 cm for women.

When controlling weight, it is suggested that the daily calorie should be limited to ≤500-750 kcal, and the exercise mode should be moderate to high-intensity aerobic exercise for 30-60 minutes every day, 5-7 days/week, reaching 60%-90% of the maximum heart rate.^④

6. Be sure to quit smoking and limit alcohol.

Do not smoke, quit smoking completely, and avoid passive smoking. If you drink alcohol, you should reduce your alcohol intake. Men ≤ 20g/day, women ≤ 10g/day. It is best to give up drinking.^④The safest drinking amount is 0, that is, no drinking.

7. Reduce stress in your life.

The intense pace of work and life, heavy ideological pressure, emotional excitement, anxiety and frequent overtime and staying up late will make the nervous system and hormone levels in the human body adjust abnormally, leading to faster heartbeat and increased vascular tension, which is another common cause of high blood pressure.^⑧

The new guidelines suggest that you should breathe slowly and regularly before going to bed every day (preferably with the help of professional breathing equipment), and the target breathing frequency is < 10 times/minute, 15 minutes/time, and > 40 minutes per week.^④

In addition, meditate for 20 minutes twice a day; And spending 30 minutes a day doing yoga three days a week also helps to relieve stress.^④

The popular science education for young people has been solidly promoted.

　　In recent years, all localities have solidly promoted popular science education, promoted popular science resources to enter primary and secondary schools, encouraged students to enter off-campus popular science bases, and improved the evaluation and guidance of popular science education effects, so that the majority of young people can approach science and fall in love with science. The National Science Popularization Day in 2023 was held in various places from September 17th to September 23rd. In this edition of education, let’s focus on the active exploration in developing popular science education and improving young people’s scientific quality in several places.

　　Professionals act as the main force of popular science

　　[lens]

　　"Students, what do you think the painter Leonardo da Vinci and the surgical robot Leonardo da Vinci have in common?" "They are all creators, but their fields are different." Peng Yaqin, a graduate student at the Institute of Automation, China Academy of Sciences, was pleasantly surprised by the philosophical and childlike answers given by primary school students in the popular science class at Taishitun Town Central Primary School in Miyun District. On the podium, Peng Yaqin explained the application of artificial intelligence in surgical medicine in a simple way. Under the podium, the students listened with relish and interacted with the teacher in real time.

　　In the "Vernal Equinox Project" youth science popularization special action of the University of Chinese Academy of Sciences, such scenes happen from time to time. "What kind of science and technology feast will volunteer brothers and sisters bring this week?" The weekly popular science class has become the expectation of small science and technology fans in more than 30 primary and secondary schools in Miyun, Huairou and other districts of Beijing.

　　"In 2018, on the occasion of the 40th anniversary of the founding of the University of Chinese Academy of Sciences, the school launched the’ Vernal Equinox Project’ youth science popularization special action. Relying on the strength of teachers and students of the Science and Education Integration College of the National Science and Technology University, we are committed to improving the scientific literacy of young people in the form of popular science reports, scientific and technological counseling, and public welfare education. " Liu Weiqiang, Minister of Propaganda Department of the Party Committee of National Science and Technology University, introduced.

　　Why are there so many pits on the moon? How do bees make honey? How to make the chip … Only last semester, the graduate students of the National Science and Technology University of China gave more than 1,800 interesting and informative popular science reports, which conveyed the happiness of scientific creation to young people and made the buds of science grow sturdily in their hearts.

　　"Students, knowing yourself is an important topic in life." Yu Wanrong, a graduate student from the Institute of Psychology, Chinese Academy of Sciences, gave a popular psychological science report to the students of the Sixth Primary School in Huairou District, Beijing. From theory to experiment, clever introduction and patient explanation, the 45-minute course taught students how to treat psychology scientifically and their emotional changes.

　　Through the help of graduate students in primary and secondary schools, the teachers of Huairou Sixth Primary School are full of praise for this way. In their view, the "vernal equinox project" has nurtured the scientific seeds in children’s hearts like spring breeze and rain.

　　"There are more than 100 teachers behind the many courses of the Vernal Equinox Project to provide guidance for graduate students who participate in popular science, and strive to bring students the best experience and harvest in each class. Behind this, more than 100 teachers from the National Science and Technology University are quietly paying. " Wu Baojun, executive deputy secretary-general of the National Science and Technology Association, introduced.

　　"The’ Vernal Equinox Project’ not only serves the science education in primary and secondary schools, but also helps to cultivate the social responsibility and responsibility of the students of the National Science and Technology University." Wang Yanfen, executive deputy secretary of the Party Committee of the National Science and Technology University, expressed the hope that the students of the National Science and Technology University will realize the personality temperament and value pursuit of "erudition and dedication" and achieve all-round development in the practice of serving the society.

　　Innovative activities enrich popular science carriers.

　　In front of the exhibition board of "Beautiful Days and Beautiful Elephants" weather station in Qibao Zhenming Qiang Primary School, Minhang District, Shanghai, students are concentrating on changing today’s weather information. "This week’s weather forecast is at the forefront", "Daily dressing suggestions are posted here" and "You don’t have to worry about getting wet with rain gear reminders" … This is the epitome of the project-based learning course of "Tips for Self-made Meteorological Life" in Mingqiang Primary School. Students collect, record and sort out weather information under the guidance of teachers, make judgments based on life experience, and apply meteorological knowledge to daily life.

　　Since 2020, Mingqiang Primary School has vigorously carried out meteorological science popularization activities, and the east and west campuses have successively established campus meteorological stations and smart learning spaces. With the support of the professional meteorological department, the school has developed a series of scientific practice activities suitable for students of different grades. "We hope that students can feel the wonder of meteorological science in the experience activities of interesting needs, learn to study independently and carry out innovative practice." Liu Yiting, vice president of Mingqiang Primary School, introduced.

　　"How is the wind formed and what are its characteristics? How to prevent it when encountering windy weather? " Open the picture book "Meteorologist" compiled by our school, and explain the formation principle of common weather phenomena such as rain, clouds, snow and fog in easy-to-understand language, which is skillfully integrated with different fields such as art, literature and science, making the meteorological class more lively and interesting.

　　"With VR glasses on, we can appreciate the climate of the four seasons in the teacher’s digital courseware, and we can also do virtual experiments and play various games!" Zhou Qijia, a fifth-grade student in Mingqiang Primary School, is full of expectations for every meteorological class. The titles of "meteorological poet", "meteorological anchor" and "meteorological researcher" have witnessed her achievements in the process of meteorological learning.

　　The basic education stage is the key stage to cultivate scientific spirit and enhance innovation ability. As an important educational subject, primary and secondary schools shoulder the mission of cultivating students’ scientific quality.

　　The reporter learned that at present, schools around the country strengthen science education, constantly improve the concept and mechanism, and innovate ways and means. For example, students of Shenzhen Experimental School independently produce scientific and technological works in the Science and Technology Festival to apply what they have learned; At Baiyinchagan No.1 Primary School in Chahar Right Wing Houqi, Inner Mongolia Autonomous Region, students tried to operate a 3D printer, carry out modeling design and experiments, and enhance their interest in science and technology innovation through personal experience …

　　Xia Yuhua, secretary of the Party Committee of Shenzhen Experimental School, said, "It is our most desirable effect to inject knowledge into children’s minds through excellent practical courses, stimulate interest in practice and let children explore independently."

In rencheng district Erlipu Middle School in Jining City, Shandong Province, the arrival of the popular science caravan made the whole campus boil. Cutting-edge scientific devices and scientific interactive experience devices lined up, and popular science exhibits covering light, power, mathematics, sound, electromagnetism, physics and other disciplines made a stunning appearance, bringing students a feast of popular science integrating knowledge and interest.

　　The popular science caravan is a "mobile science and technology museum", which can send rich popular science knowledge to rural children and effectively satisfy their curiosity about science. The students in Erlipu Middle School learn the nutrients of knowledge by discussing the principle of exhibits and feeling the mystery of science at zero distance. "These lively and interesting experience projects let us understand science, approach science, feel the strength of the motherland’s scientific and technological strength, and stimulate a strong interest in science and technology." The students present said happily.

　　In recent years, Jining City has been equipped with 7 popular science caravans and more than 200 pieces of mobile science and technology museum series exhibits, and has carried out nearly 1,000 activities in the campus and countryside, benefiting more than 10,000 young people. "The popular science caravan is mobile and flexible, integrating knowledge, fun and interaction, which can make rural children experience the charm of science more intuitively and narrow the distance between science and daily life." The relevant person in charge of Jining Science and Technology Association introduced.

　　In the No.1 Primary School of Zhangguangmiao Town, Gushi County, Xinyang City, Henan Province, rural children feel the charm of science in interesting experiments. Drink bottles are made into "water rockets", and plastic ropes are made into "electrostatic octopus" … Zhang Jiantao, a science teacher, leads students to "play" science with things that can be seen everywhere, guiding students to participate and explore.

　　"I remember taking the children to experience the formation of wind in the first experimental class. Everyone assembled teaching AIDS and lit candles. After seeing the hot air rising to push the wind wheel to rotate, the children jumped up excitedly. They all have light in their eyes. I know that it is a longing for science and a yearning for science to illuminate a better future. " Zhang Jiantao said.

　　Nowadays, under the leadership of Zhang Jiantao and other science teachers, students actively participate in various scientific and technological competitions at all levels and win back many awards. According to reports, science experimental classrooms have been built in Gushi County, and each grade has at least one science class every week, forming a strong atmosphere of stressing, loving, learning and using science.

　　"There are still problems and deficiencies in China’s science education, such as weak overall foundation and uneven regional development, which need to be strengthened and improved urgently." The relevant person in charge of the Ministry of Education said that it is necessary to accelerate the development of rural science education and effectively improve the quality of rural science education. We should provide corresponding science education resources for science education places in weak areas and schools, and at the same time develop science education courses with local characteristics, so as to continuously narrow the gap between urban and rural areas, regions, schools and groups in science education and ensure that "no one can be less".

What is the intention of the US, Japan and India aircraft carriers gathering in the Bay of Bengal for military exercises？

On July 10th, a joint maritime military exercise between Japan, the United States and India was launched. Vision china

On July 10th, local time, the "Malabard" military exercise jointly held by India, the United States and Japan officially kicked off near the Bay of Bengal in India.

It is interesting to note that all three countries participating in the exercise have deployed their largest warships for this exercise, with the largest scale in the past years. India sent its only aircraft carrier "Vikla Matia" to participate in the exercise, the United States sent the aircraft carrier "Nimitz" with F/A-18 fighters, and Japan also sent its 20,000-ton helicopter carrier "Izumo". The gathering of three aircraft carriers in the Bay of Bengal is the first time in the history of the "Malabard" joint military exercise.

In this regard, military commentator Liu Zhenglu said in an interview with the Science and Technology Daily reporter: "It is not difficult to see that the scale of the’ Malabard’ military exercise is unprecedented. By conducting such large-scale sea exercises with the United States, Japan and other maritime powers, India can enhance the naval combat capability and strengthen its military superiority in the Indian Ocean. At the same time, it will convey good relations between India and the United States and Japan to the world, and deter India’s strategic opponents from the side to curb the trend of expanding military presence in the Indian Ocean by extraterritorial countries. "

India sent the strongest lineup.

The "Malabard" military exercise is a normal exercise in which India and the United States jointly carry out regional security and defense and strengthen military cooperation in the Indian Ocean. Because the sea area where the exercise was first held was near Malabard, the west coast city of India, it has been called the "Malabard" military exercise for years. The motive of the exercise is to strengthen the common defense at the end of the first island chain in the Indian Ocean, and to strengthen the control and blockade of maritime routes and strategic passages in the Indian Ocean.

According to Liu Zhenglu, from the previous exercises, the main exercises of the "Malabard" joint military exercise are common exercises such as maritime air defense, joint anti-submarine, joint sea control, maritime blockade and maritime communication, and there are also low-intensity exercises such as joint patrol, maritime search and rescue, and temporary inspection and arrest.

This time, India dispatched its only active aircraft carrier, the Vikla Matia. This is the first time that it has conducted a comprehensive combat exercise alone with foreign fleets since its service in November 2013. This aircraft carrier was introduced by India from Russia and modified from the "gorshkov" aircraft carrier. It is now the "trump card" of the Indian navy. Its battle cluster contains the essence of the Indian Navy, and the Kolkata class destroyer, the Sh Oillic class frigate, the Talwar class frigate and the Camol Tower class anti-submarine frigate are all its "imperial guards", while the Kilo class submarine imported from Russia is also the main force of the underwater combat force of the carrier battle group.

"However, the modification of this aircraft carrier is not particularly successful. Its island is too close to the middle of the flight deck, which seriously affects the take-off and landing efficiency of carrier aircraft. Moreover, its power system is not reliable, and seven of the eight boilers failed during the trial. The carrier-based aircraft it carries is the MIG -29K carrier-based aircraft imported from Russia. Although it has been modernized and upgraded, the weight of weapons and equipment that can be carried is low because of the limited space and short range. " Liu Zhenglu said.

He said: "India has sent the strongest team in this military exercise. On the one hand, India is the host country of the’ Malabard’ exercise, and on the other hand, it shows off the strength of the Indian navy to the world and shows its hegemonic position in the Indian Ocean. Of course, the Indian navy has made great progress in armament construction in recent years and has the ability to send advanced ships. "

The purpose of Japan’s participation is not simple.

The reporter learned that the United States and India began to implement the "Malabard" joint military exercise in 1992. In 2007, Japan Maritime Self-Defense Force was invited to participate for the first time, then in 2009 and every year after 2014. In this joint military exercise, Japan sent its largest tonnage helicopter carriers "Izumo" and "Lian" frigates.

Izumo is the latest warship in Japan Maritime Self-Defense Force, with a standard displacement of 19,500 tons and a full displacement of 27,000 tons, which exceeds the Italian navy’s 13,000-ton aircraft carrier garibaldi, the Spanish 17,000-ton aircraft carrier Prince Asturias and the British Royal Navy’s 21,000-ton "invincible" class aircraft carrier.

"Although Japan claims to be a destroyer, it has an island-shaped building, a large flight deck and a large hangar. Its deck can take off and land heavy helicopters, and it can take off and land F-35B fighters after modification, so it is actually a light aircraft carrier." Liu Zhenglu said.

"It should be said that the purpose of Japanese participation in the’ Malabard’ exercise is not simple. The first is the consideration of strengthening cooperation with India. In recent years, for the purpose of jointly fighting against China, Japan and India have many "common languages", and the trend of jointly fighting against China has become more and more obvious. Therefore, strengthening the ties and cooperation between the two armies and countries through military exercises has become an important consideration for Japan. Of course, the joint performance with the US and Indian troops will also enhance Japan Maritime Self-Defense Force’s combat capability. " He pointed out, "On the one hand, the Izumo was dispatched to enhance its combat effectiveness, demonstrate its advanced performance and highlight Japan’s overseas influence by participating in exercises. On the other hand, sending the heaviest warships also shows Japan’s’ sincerity’ in participating in joint military exercises, thereby bringing closer feelings with countries such as India. "

Liu Zhenglu stressed: "In recent years, the Japanese government’s rightwing has become obvious, and it has repeatedly acted on issues such as lifting the ban on self-defense, sending troops overseas, and exporting weapons. By participating in overseas joint exercises, it can highlight the existence of Japan’s overseas self-defense forces and provide assistance for their’ revision of the constitution’."

The participating ships are specially equipped for "submarine search"

The 10-day drill includes submarine familiarization training, air defense, search and anti-submarine warfare. However, the Indian navy admits that anti-submarine warfare is the core content of the whole exercise. Coincidentally, on the eve of the exercise, many Indian media reported that "China submarines entered the Indian Ocean" and "14 China warships were unusually active in the Indian Ocean", hyping up China submarines’ activities in the Indian Ocean. This has to make people guess the pertinence of this so-called routine military exercise.

Look at the ship lineup of India, the United States and Japan: the United States sent the Nimitz aircraft carrier with F/A-18 fighters, a Ticonderoga-class guided missile cruiser, an L.A.-class attack submarine, and an aircraft carrier battle group consisting of three to four arleigh burke-class guided missile destroyers. India has sent six to seven frontline warships, a Kilo-class submarine and the aircraft carrier Vikla Matia. Japan sent the "Izumo" helicopter carrier and another warship.

Liu Zhenglu pointed out: "This lineup is quite luxurious. The configuration of the US aircraft carrier battle group is very standard, and cruisers, destroyers and nuclear submarines are readily available. India and Japan are also the best. "

"In addition to the world’s first-class air defense capability, this battle group has a strong ability to search for submarines and anti-submarine warfare, which is mainly reflected in the fact that the Ticonderoga-class guided missile cruiser and the arleigh burke-class guided missile destroyer are equipped with advanced towed sonar, and can also carry out aviation anti-submarine through helicopters. At the same time, the LA-class nuclear submarine itself is anti-submarine warfare’s trump card. At the same time, the specialty of the quasi-carrier Izumo is anti-submarine, because the ship-borne helicopter it carries is the main force of anti-submarine warfare. The Indian navy is also equipped with Ka -28 and Neptune anti-submarine helicopters, and the anti-submarine capability of Kilo-class conventional power submarines is also excellent. Therefore, the anti-submarine capability of the joint exercise of the three countries is still relatively strong. " Liu Zhenglu said.
