| 摘 要： | 利用四极质谱计（QMS）法测量了Ti、Zr、Er及Nd等4种单质金属的氚化物3He释放，通过数年监测与数据积累，对这4种金属氚化物的3He释放行为进行了比较研究。结果表明，它们贮存早期的3He释放速率极低，其释放速率均不及生成速率的1%，其中，Ti、Zr氚化物3He释放系数（RF）为10－6～10－5量级，Er、Nd氚化物的3HeRF为10－3量级，随着贮存时间的增加，当金属氚化物内积累较多的3He时，其RF会迅速增长至10－1量级，释放速率接近生成速率。

| Abstract: | 3He release from 4 kinds of metal tritide such as Ti, Zr, Er and Nd were measured by means of QMS method. Comparison of 3He release behavior among them shows that their 3He release rates are very low which are less than 1% of their 3He generation rate, and 3He release factors are 10－6-10－5 for Ti and Zr tritides and 10－3 for Er and Nd tritides. Their 3He release factors will increase rapidly to 10－1 level while enough 3He accumulates in metal tritides with storage time increase. |
