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。
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.
这个图表给你们一个重要的,可裂变和可转换核素的,一些临界热能中子横截面的总结。
This chart gives you a summary of some of the critical thermal-neutron cross sections of important fissile and fertile nuclides.
对于长寿命裂变产物核素热中子反应截面测量，除了上述意义外，在废物处理处置方面也具有实际应用价值。
The measurement of thermal neutron cross sections of long-lived fission products (LLFPs) also has practical application value in nuclear waste disposal.
