These names come from the fact that the source of energy the nucleus, or core, of the atom, Nuclear fuels much as plutonium and uranium give off heat energy when fission (the splitting of atoms in these fuels)occurs.

这个名称来自于原子能来源于核、或者原子核这样的事实。当核燃料,例如钋(应该为钚)和铀,发生核裂变时释放出热能(这些燃料中原子发生分裂)。

The energy appears as kinetic energy of the fragments, which converts to thermal energy as the fragments collide in matter and slow down. Fission also releases two or three free neutrons. The free neutrons can bombard other nuclei, leading to a series of fissions called a chain reaction.

这些能量表现为碎片的动能,当碎片与物质碰撞时,碎片的动能转化为热能,碎片的运动就慢了下来。裂变还释放出两到三个自由中子。自由中子可以轰击其它的核,导致一系列的裂变,称为链锁反应。
