The explosive decomposability of ethylene will lead to much large temperature gradient and great range thermal stresses response on thick wall of reactor.
由于乙烯爆炸性分解，在反应管壁厚上形成极陡的温度梯度和幅度很大的热应力。
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。
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。
