As Masurium, it was the first element discovered that occurs in nature only from spontaneous fission, and as Technetium, it was the first element discovered in a laboratory.
铀燃料是由中子导致的核裂变产生的能量加热的。
The uranium fuel generates heat by neutron-induced nuclear fission.
有些核裂变产生的副产品自身具有放射性。
Some byproducts of the nuclear fission are themselves radioactive.
那些是关键的参数，因为这些数目越高，每个裂变产生的中子就越多。
Which are also very key parameters because the higher these Numbers are the more neutrons are produced per fission.
有些核裂变产生的副产品自身具有放射性。这些物质的衰变，也在产生热能。
Some byproducts of the nuclear fission are themselves radioactive.These decay, producing heat.
权力裂变虽是不良现象，但通过权力调整可以减少、弥补权力裂变产生的不利影响。
Power fission although is a bad phenomenon, regulation can reduce or remedy power adverse effects that fission brings about.
权力裂变虽是不良现象，但通过权力调整可以减少、弥补权力裂变产生的不利影响。
Although power fission is a bad phenomenon, power adjustment can reduce and remedy the negative influence brought about by power fission.
这一试验的原理是运用核裂变产生的热量给氢气加温，导致其膨胀，并产生推动火箭的力量。
The idea behind the reactor was to use the heat generated by fission to heat hydrogen, which would expand, generating the force to push the rocket.
燃料储量丰富，过程安全，废料尽管有放射性，但同裂变产生的废料相比，有害程度要小得多。
The fuel is abundant, the process safe and the waste, though radioactive, is far less noxious than the stuff left over from fission.
核裂变产生的能量极其巨大——相比同等质量的普通燃料如汽油等，核裂变材料释放出的能量要多出几百万倍。
Nuclear fission produces insane amounts of energy — we're talking several million times more energy than you'd get from a similar mass of a more everyday fuel like gasoline.
核裂变连锁反应发生时，导管被加热到极其高的温度，将热量安全导出则意味着可以提取裂变产生的可利用能量。
During a nuclear fission chain reaction, the tubes heat up to extremely high temperatures, and the way to keep them safe turns out to also be the way to extract useful energy from them.
如你们想的，我有一个高的能量级，那样有很多的裂变产生，我们有一个共鸣的区域，然后我们有热能区域。
And as you can recall we had the high energy level where there were fissions occurring, we had a resonance region and then we had a thermal region.
