Yu Min, an important promoter and pioneer of China's defense technology reform and development,He passed away in Beijing on January 16th at the age of 93.Made significant contributions to China's national defense and military affairs.
Yu Min is a Chinese nuclear weapons scientist and a member of the academic department of the Chinese Academy of Sciences. He has won the Medal of Two Bombs and One Star, the highest national science and technology award“The father of China's hydrogen bomb”The title.
Under his organization and deployment, the hydrogen bomb theory was able to break through.On June 17, 1967, a mushroom cloud rose from the depths of the Lop Nur Desert, and China successfully conducted a hydrogen bomb test. From the explosion of the first atomic bomb to the successful test of the first hydrogen bomb, it took the United States over 7 years, the Soviet Union 4 years, and China 2 years and 8 months.
In October 1964, China's first atomic bomb was successfully detonated under the leadership of Deng Jiaxian's team. Subsequently, the research and development team led by Yu Min developed China's first hydrogen bomb in 1967, making pioneering contributions to the improvement of China's independent scientific and technological innovation capabilities and the enhancement of its national defense strength.
On January 9, 2015, Yu Min won the 2014 National Highest Science and Technology Award, and on April 3 of the same year, he was awarded the Phoenix Satellite TV's“Lifetime Achievement Award for Chinese People Who Influence the World”。
At the celebration of the 40th anniversary of reform and opening up on December 18, 2018, the Central Committee of the Communist Party of China and the State Council decided to award the title of Reform Pioneer and the Reform Pioneer Medal to 100 comrades including Yu Min.
Last centurySince the 1980s, Yu Min and his team have made breakthroughs in key technologies in the development of second-generation nuclear weapons, taking China's nuclear weapon technology to a new level.
Since the beginning of the research and development work, Yu Min has not had a normal schedule and has been working hard for years to study, resulting in serious stomach problems. He was sent to the emergency room several times after resting, but these difficulties did not stop him. The achievements of our country today cannot be separated from these researchers, and today's news has made many citizens feel particularly regretful and heartbroken. This respected old academician has devoted his entire life to the country.
Yu Min was born inAugust 1926. In 1944, Yu Min was admitted to the Department of Mechanical and Electrical Engineering at Peking University. In 1946, driven by his passion for theoretical physics, Yu Min transferred to the Physics Department of the College of Science and established theoretical physics as his major. In 1949, Yu Min studied under Zhang Zongsui as a graduate student and also served as a teaching assistant.
In order to develop China's own hydrogen bomb as soon as possible, Yu Min worked tirelessly.“Hundred Day Battle”Unforgettable.For over 100 days and nights, Yu Min first buried himself in the mountains of computer paper tapes, and then gave intensive reports, leading everyone to discover the key to self-sustaining thermonuclear combustion of hydrogen bombs, finding the technological path to break through hydrogen bombs, and forming a complete physical design scheme for hydrogen bombs from principles, materials to configurations.
It is reported that there are currently only two hydrogen bomb configurations in the world, the United States'Teller Ulam configuration and China's Yu Min configuration. The Teller Ulam configuration decryption has relatively more information, which uses X-rays generated by the explosion of primary small atomic bombs to heat and compress secondary fusion materials, triggering more intense nuclear fusion reactions. It is rumored that the Yu Min configuration is lighter than the Teller Ulam configuration, but there is not much publicly available information in this regard.
In the breakthrough of the hydrogen bomb principle, a series of fundamental problems in the physics of thermonuclear weapons were solved, and a key role was played in proposing a basic and complete design from principle to configuration. Long term leadership and participation in the theoretical research and design of nuclear weapons have solved a large number of critical theoretical problems. fromSince the 1970s, it has played an important role in advocating and promoting research on several high-tech projects.
