摘　　要：本工作研究不同温度下钛吸收氕氘混合气体的特性，并计算其分离因子α。结果表明，在100～300℃温度范围内，Inα与温度T的倒数间存在线性关系Inα=-0．13＋107／T。在200℃下，当混合气中的氘浓度在10．0％～87．2％范围内变化时，钛吸收氕氘混合气的分离因子恒定不变。钛对氕氘混合气的吸收存在明显的同位素效应，钛更易于吸收氕气。The characteristics of absorbing H2-D2 mixture in titanium was researched and the separation factor of hydrogen isotopes was measured. It is found that there is a linear relation between the separation factor＇s logarithm and absolute temperature＇s reciprocal as Inα=-0.13＋107/T in the temperature range of 100-300 ℃. The separation factors of titanium absorbing mixed gas with various composition at 200 ℃ are independent of the composition of mixed gas, and there is an obvious isotope effect for the absorption of H2-D2 mixed gas in titanium and it is easier to absorb protium in titanium.
