One of the pioneers in the development of China's first atomic bomb and one of the founders of China's nuclear weapons test. It is the first in China to calculate the core temperature and pressure of atomic bomb explosion. The study of its implosion mechanism solves the key problems of the atomic bomb and provides an important basis for the explosive power and structural design of the atomic bomb. He founded the Institute of Nuclear Tests, successfully designed and presided over dozens of nuclear tests in different ways, such as the first atomic bomb, hydrogen bomb, missile nuclear weapon and enhanced atomic bomb, which promoted the coordinated development of nuclear weapon design, improvement and test technology. He is the designer of the overall technology of nuclear test, put forward the suggestion of changing underground nuclear test in time, and organized the transformation of atmospheric test to flat hole and shaft test in a short time. The establishment of China's own systematic nuclear explosion and its effect theory laid the foundation for the application of nuclear weapons in our army. It initiated the test and research of nuclear explosion, and played an important role in the development and improvement of weapons, the study of effects and protection. It has created a new field of anti-nuclear reinforcement technology and completed the first anti-load test. 1985 won the national special prize for scientific and technological progress. In 1990s, the group management project of Jilin University State Key Laboratory of Superhard Materials was organized, and the TFD theory of Cheng was used to guide the research of superhard materials, which made an important contribution to the development of iron-based catalysts for diamond synthesis.

Winner of the highest national science and technology award in 20 13, a famous physicist, founder and leader of China's nuclear test science and technology, academician cheng, a meritorious scientist of "two bombs and one satellite", winner of the highest national science and technology award in 20 13.

I think he has made an indelible contribution to the country. When he was young, he was thought to win the Nobel Prize (if he stayed in the West), but he chose to return to the motherland when he needed talents most (I admire him for this alone).
