| 摘 要： | 运用ＲＨ－４０２测氢仪测定具有高挥发性锂的铝－锂合金的固态氢含量具有相当难度。本文就如何鉴别体内氢和表面氢、如何选择加热功率和加热时间及试样大小做了大量探索实验，初步形成了可行的铝－锂固态氢含量的分析方法。同时就测量的误差来源及测氢过程中应注意之点进行了讨论。结果重复性好，且结果比较准确（利用俄罗斯铝－锂合金氢标样比较）。

| Abstract: | High volatility element Li exists in 2091 Al Li alloy,and makes the difficulty for the determination of hydrogen.A lot of tests were done,for example,how to distinguish the body and surface hydrogen,to choice heating power,heating time and the size of sample.Then the analytical method is established and many discussions were done.The reproducibility and accuracy is satisfactory,and compared with the Russian Al Li alloy hydrogen standard sample. |
