正比计数管是探测中子的关键技术之一，而正比计数管内气体的倍增机制是影响其性能的主要因素。本文总结了现有的9种不同的气体倍增表达式，分别阐述了各自的推演过程、应用范围和对应的各项参数值。并通过对比，最终发现Diethorn公式最简便，能在一般的场合得到较好应用，目前使用广泛；半微观公式能统一地表述各种情况下的气体倍增关系，但只在部分场合中得到验证，参数还不够完全，完善各项参数也是当前正在研究的工作。

Proportional counter is one of the key techniques of neutrondetection,whist the gasmultipli cation mechanismis the main factor of affecting property.Nine different gasmultiplication for mulasaresummarizedin this paper,the deriv atio nprocess,applying scope and every corres ponding factors are il ustrated separately. After comparison, it is clear that the Diethorn formula is the most simple and can be used in general situation extensive;the se-mi- microscope formula can express the gasmultiplication relationshipin every situations,while is validatedonly in some limited cases and the parameter values are not complete,so some resear chesare developed for the moment.
