1 954 March1day, the first practical hydrogen bomb (also a real hydrogen bomb) in the United States was successfully tested in Bikini Island. The predicted equivalent is 6 million tons, and the actual equivalent is as high as 6.5438+0.5 million tons. Subsequently, with the help of the United States, Britain conducted its first hydrogen bomb experiment on May 1957.
19665438+On February 28th, China successfully conducted the principle test of hydrogen bomb, with an equivalent of 300,000 tons. At 8: 20 am on June 1967, the plane successfully dropped 3.3 million tons of equivalent hydrogen bombs.
1in August, 968, France also had a hydrogen bomb. It took seven years and three months for the United States to explode the first atomic bomb and the first hydrogen bomb, four years and seven months for Britain, less than four years for the Soviet Union, eight years and six months for France and two years and eight months for China.
It took China four and a half years less than the United States to develop the hydrogen bomb.
"After the atomic bomb exploded, the development of hydrogen bomb technology was put on the agenda." Li recalled that in June 1964+ 10/6, after China's first atomic bomb exploded successfully, China got the "admission ticket" to the nuclear power club.
But the development of hydrogen bomb is more complicated than that of atomic bomb in theory and manufacturing technology. "Compared with the atomic bomb, the hydrogen bomb is not only a breakthrough in quantity, but a qualitative change and a breakthrough in principle."
However, China people completed the breakthrough from atomic bomb to hydrogen bomb at the fastest speed in the world. After China's first atomic bomb exploded successfully, Premier Zhou put forward a request: try to test the hydrogen bomb device at 1968. However, scientists from China unexpectedly advanced this time. China is the fifth country with an atomic bomb in the world, but the hydrogen bomb has surpassed the French and become the fourth in the world.
