| 摘 要： | 本文从多组分同位素的扩散方程出发，推导了多组分同位素离心分离径向平均丰度的丰度方程。用迭代法结合流场近似解数值模拟了４组分同位素ＵＦ６和ＳＦ６的丰度分布，并估算了同位素单位摩尔质量差下的全分离系数。同时还分析了同位素间相对全分离系数与其摩尔质量差的关系及离心机流场近似解中一些参数的取值问题。

| Abstract: | The expressions of diffusion equation for multicomponent isotope separation bygas centrifuge are derived by utilizing the simplified diffusion transportvector. A method ofradial averaging which was restricted to a binary mixture is extended to multicomponentisotope mixtures by using an iterative scheme. A numerical analysis of tetradic UF, or SF,gas isotope separation by centrifuge is discussed when a special model of velocity distributionis given. The dependence of mutual separation factor for the components on their molecularweights' difference is obtained. Some aspects of the given model of gas fluid are alsodiscussed. |
