摘　　要：在离心级联分离多组分稳定同位素过程中,找出组分间的全分离因子同它们的相对分子质量差之间存在的确定性关系,有利于级联的分离计算和实验研究。建立了实验数据可靠性分析原则,确定了符合实验条件的数据;得到在定常态下短离心级联中,任意组分间的全分离因子与其组分间的相对分子质量之差存在指数关系。应用所建立的级联全分离因子关系式,对文献中发表的离心级联分离稳定同位素的实验数据进行了分析研究和补全工作。Research, especially experimental research, would be greatly facilitated by a relationship between the overall separation factor of a gas centrifuge cascade and the relative molecular mass difference between any two components. This paper presents a principle for analyzing the reliability of experimental data to filter experimental data obtained with a short gas centrifuge cascade. Analysis of the filtered experimental data gave an exponential relationship between the overall separation factor of the cascade and the relative molecular mass differences. The incomplete experimental data from separation tests with gas centrifuge cascades released by Russian researchers was then supplemented using this exponential relationship.
