So if we start up here, fast neutrons produced by fission, by thermal fission and then you add the total number of fast neutrons produced. 如果我们在这开始，生产的快速中子,通过裂变，通过热能裂变,你加入生产的快速,中子的全部数量。 - 2
So you have neutrons actually getting into the thermal energy range and then these neutrons become absorbed, not capable of producing fission. 所以，你得到中子会进入到,热能范围里，然后这些中子,变成吸收的，不能够产生裂变。 - 3
We can then look at uranium 238 which has a relatively low absorption thermal energy range and essentially has no fission cross section which is why we call uranium 238 a fertile atom. 我们能看看铀238，它有一个，相对低的吸收热能范围，基本上没有裂变横截面，那就是为什么我们称铀238为可转换核素。
