摘要

除了常规矩形级联和阶梯级联等模型外,还有一些其他的级联模型,使用这些特殊级联可以达到特殊分离目的。本文提出一种用于中间组分同位素分离的特殊级联"T"级联。该级联模型可以通过一点供料三点取料的模式,直接提取中间组分同位素。以氙同位素为例,进行理论计算,"T"级联可以一遍分离直接获取丰度90%以上的~(131)Xe同位素,略高于双级联分离能力。结果表明,"T"级联适合进行中间组分同位素的一遍提取分离。
        There are some especial cascades which can be used to do some especial study,including ladder cascade,square cascade and other cascades.This paper put forward a sort of cascade model that is "T"cascade is used to enrich the constituent of middle isotope.The cascade is in the same shape with letter of"T",and it can use one feed and three produces to enrich the constituent of middle isotope to the needful abundance by one time.The cascade used to enrich the isotope of ~(131)Xe that can make the abundance of~(131)Xe isotope to 90% or more for target by one time,and separating power of two cascades is slightly less than separating power of"T"cascade.The result can show that"T"cascade can enrich the constituent of middle isotope to the needful abundance by one time.
