本文在５×１０－ ２ ～５×１０－ ３ Ｐａ真空条件下和１８２３～２０２３Ｋ 温度范围内对金属铽的蒸馏速度进行了实验测定及理论计算。对比分析了实验测定结果与理论计算结果的差别及其原因，提出了提高金属铽蒸馏速度的措施。
In this paper, 5 × 10-2 ~ 5 × 10-3 Pa vacuum conditions and 1823 ~ 2023K temperature range of terbium metal distillation rate of the experimental determination and theoretical calculations. The differences and the reasons between the experimental results and the theoretical ones were analyzed and compared. The measures to increase the rate of terbium metal distillation were put forward.
