本文研究了LaNi_5在不同温度和压力下的活化过程。结果表明,LaNi_5的活化可分为三个阶段,即孕育期;吸氢速度随时间增加而增加的第一阶段和吸氢速度随时间增加而减少的第二阶段。讨论了每一阶段的特征,并给出了吸氢速度的近似表达式。
A study was made of the activation process of LaNi_5 under various temperatures and pressures. Three periods of the process seem easily to be distinguished, namely, the incubation period, the increment and decrement periods of H_2 absorption with prolongation of the exposure time. The different features among them were discussed and approximate expressions of the hydrogenating rate were given.
