| 摘 要： | 提出了一种新的改进运行方式的脉冲级联，能减小脉冲级联过渡过程的最终脉冲数，缩短过渡时间，在工程上更易实现。与常规级联相比，用这种脉冲级联分离多组分同位素混合物，能用较少的级数和离心机数目得到相同的目标同位素丰度。而利用相同长度的级联和相同数量的离心机构成矩形级联，中间组分的精料丰度在脉冲级联中更高，其贫料丰度在脉冲级联中更低。通过优化在级联中部的适当位置增加适当大小的附加取料，脉冲级联能获得的中间组分产品的丰度远较常规级联能获得的丰度高。

| Abstract: | A new operation manner of pulse cascade was proposed.Compared with the pulse cascade without the improvement,smaller final pulse number and shorter transient time are needed,and it is more feasible in engineering.In separating multicomponent mixtures,compared with the conventional cascades,this improved pulse cascade is able to obtain the same degree of separation with shorter cascade lengths and fewer centrifuges.In the case that the cascade lengths and the total numbers of centrifuges are the same for sep... |
