During World War II, when American scientists were studying "heavy element" uranium and its isotope plutonium, some scientists foresaw the possibility of using enough heat generated by fission reaction to fuse hydrogen. 1943, people began to imagine making hydrogen bombs. 1949 In August, the explosion of Soviet practical nuclear weapons successfully broke the nuclear monopoly position of the United States, prompting Americans to step up their hydrogen bomb tests. Taylor organized the research work of hydrogen bomb with great enthusiasm, and completed all the theoretical research of hydrogen bomb by the end of 1949. 1950 65438+ 10 In October, US President Truman issued an order to develop a hydrogen bomb. 1950 On February 24th, the Joint Chiefs of Staff of the U.S. Department of Defense adopted the decision of "immediately and comprehensively developing the means of production and transportation of hydrogen bombs". The hydrogen bomb was finally made. This hydrogen bomb consists of an atomic bomb surrounded by about one ton of highly compressed liquid hydrogen. During the explosion, the temperature of hydrogen rose to 90 million degrees Celsius, which was enough to start the fusion reaction, thus releasing a large amount of nuclear energy, and the generated heat energy was hundreds of times that of the atomic bomb, of which the atomic bomb played a role in detonating. 1 952165438+1October1,the first hydrogen bomb was successfully tested on Bikini Atoll in the Marshall Islands in the Pacific Ocean. This hydrogen bomb is equivalent to/kloc-0.04 million tons of TNT, and its power is 800 times that of the atomic bomb dropped on Hiroshima, Japan. After detonating on a steel frame hundreds of meters high, the whole island and steel frame sank into the depths of the Pacific Ocean in a huge explosion field, which shocked the world again.
1967 On June 17, the first hydrogen bomb was successfully exploded in western China. This test is another leap in the development of China's nuclear weapons after the successful explosion of the first atomic bomb, marking a new stage in the development of China's nuclear weapons.
