摘　　要：通过计算设计了热扩散法分离氖 (Ne)同位素的工艺参数 ,并进行了单柱试验 ;在此基础上设计了Ne同位素分离的热扩散级联装置 ,应用于2 2 Ne同位素的分离 ,得到了2 2 Ne同位素浓缩的动力学曲线及装置的浓缩曲线、产率曲线。Technique parameters for stable isotope 22 Ne separation in thermal diffusion column were gained through computing, and single column experiment was carried out. On the basis of these, two thermal diffusion column cascades for isotope 22 Ne enrichment have been designed and been applied in practice. The dynamistic curve for isotope 22 Ne enrichment has been obtained, and the enrichment curve and producing curve for cascades have been given out too.It is shown that The experiment results would do a great assistance to cascade design in isotope separation.
