核武器指的是原子彈和氫彈。这里的“核”指原子核。因为原子彈和氫彈都是利用原子核反应而爆炸的。原子彈里分开放着几小塊核炸藥——純鈾~(235)(或钚~(239)),总共有一、二十公斤重。当將它們并成一塊后,能在百万分之一秒內,放出相当于2万吨TNT炸藥的能量,發生强烈的爆炸。 氫彈里放的核炸藥是氫的同位素氚和氘。当氚和氘合成氦,或者是氘氘自相結合的时候,可以放出几倍于同样重的鈾~(235)放出的能量。但是,只有在超高溫下才能發生这个反应。这种千万或万万度的超高溫是利用鈾~(235)(或钚~(239))的爆炸来达到的。
Nuclear weapons refer to atomic bombs and hydrogen bombs. The “nucleus” here refers to the nucleus. Because both atomic bombs and hydrogen bombs use nuclear reactions to explode. Atomic bombs are divided into small pieces of nuclear explosives - pure uranium ~ (235) (or 钚 ~ (239)), a total of one or twenty kilograms. When they are put together, they can release the energy equivalent to 20,000 tons of TNT explosives in one millionth of a second, causing a strong explosion. The nuclear explosives placed in hydrogen bombs are hydrogen isotopes helium and neon. When thorium and thorium are combined, or when they are combined, they can emit several times as much energy as uranium (235). However, this reaction can only occur at very high temperatures. This super high temperature of ten million or ten thousand degrees is achieved by the explosion of uranium ~ (235) (or helium ~ (239)).
