| 摘 要： | 本文研究了金属镝、钬、铒的真空蒸馏提纯效果。实验结果表明，通过真空蒸馏，金属镝、钬、铒中的气体杂质及蒸气压与基体相差较大的杂质可有效去除，去除率分别为：镝９１．４％ ，钬９４．２％ ，铒９２．９％ ；对蒸气压与基体相近的杂质元素基本无去除效果。

| Abstract: | The purifcation of Dy,Ho and Er metals has been studied by the method of vacuum distillation.The results show that gas impurities and other impurities ,their vapour pressure differs apparently from the matrix vapour pressure,can be effectivelly removed,but the imputities with vapour pressure being about the same as matrix vapour pressure can hardly be removed. |
