Recalling that we could have also fast fissions.

回想我们也可以有快速裂变。

But they do not stop spontaneous fissions in fuel rods from fuel and fission products.

但他们并没有阻止自然地发生在来自核燃料和裂变产物的燃料棒上的裂变。

The fissions (or fusions) of these localized coherent structures may occur after their interactions.

这些局域相干结构的相互作用存在裂变和聚变现象。

The free neutrons can bombard other nuclei, leading to a series of fissions called a chain reaction.

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。

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.

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。

Amid this flurry of historical fissions and fusions it is easy to overlook another, arguably more significant unification set in motion in spring 1861.

在这些历史的分分合合之中，另一件事情很容易被忽略，有些人认为这件始于1861年春天的事情才是一次更有意义的“统一”。

When enough of these neutronsproduce further fissions—rather than escaping, bouncing off or being absorbedby atoms that do not split apart—the process becomes self-sustaining.

足够多的中子就会引发进一步的裂变—不是逃走，要么撞击原子，要么被没有裂开的原子吸收—演变成自动维持的过程。
