And we've used a relatively simplistic term called Neutron Multiplication Factor which is the K that if the K equals one the neutron population is steady as is the fission rate.

我们已经使用了一个相对简单的词语，称为，中子的增殖系数，那就是K，如果K等于1，中子数，是稳定的，裂变速率也一样。

Through the analysis of the stable neutron density of the subcritical reactor with extraneous neu-tron source, this paper proves that the formula of neutron multiplication with delayed neutron is of great use in the analysis of the subcritical reactor physics.

本文主要内容是通过对有外加中子源反应堆次临界状态下中子密度稳定值的分析，说明考虑缓发中子在内的中子倍增公式对次临界状态的反应堆物理分析是很有用的。
