| 摘 要： | 作者使用增强质子背散射方法，分析了几种Mo基体纳米钛膜中氦的保持量情况．结果表明：采用离子注入法注入的氯在纳米钛膜中能保存较长的时间，氦的释放速率受氯在钛膜及基体中的分布、钛膜中氦浓度大小的影响；Ar，He混合气体放电法工作参数的选择可影响渗氦的效率。

| Abstract: | The preservation dose of helium implanted in several nanocrystal titanium films deposited on Mo substrates is analyzed by enhanced proton backscattering spctrometry. The result demonstrates that the implanted helium can be preserved for a long time in nanocrystal titanium films and its release speed is affected by the ion implantation energy, the thickness of nanocrystal titanium films and the helium concentration in nanocrystal titanium films. The choice of parameters in Ar-He gas discharge method for helium implantation is very important, which has a crucial role on the helium implantation into nanocrystal titanium films. |
