本文首先报道LaNi_5·H_6中~1H核磁共振连续波观测:高、低温下的线型、线宽的温度依赖,扩散激活能,自相关时间及基于一定模型假设计算自扩散系数.对LaNi_4Cu·H_x和LaNi_4Fe·H_x作了类似研究.通过对比得出结论:Cu,Fe部分置换Ni使氢在基质合金中稳定性增加.
The continuous wave NMR (nuclear magnetic resonance) results of ~1Hin LaNi_5·H_6, LaNi_4Cu·H_x and LaNi_4Fe·H_x were reported. The line shape at bothhigher and lower temperatures, the activation energy of diffusion, the self correla-tion time and the diffusion coefficient calculated according to a model have beendiscussed. It was concluded that the partial substitution of Cu and Fe for Ni increasesthe stability of hydrogen in the host alloy.
