应用特制双层水恒温反应器和动力学机理函数计算机拟合的方法，在３０３—３４３Ｋ温度范围内研究了ＭＬ—Ｎｉ—Ｃｏ—Ｍｎ—Ａｌ五元系和ＭＬ—Ｎｉ—Ｃｏ—Ｍｎ—Ａｌ—Ｃｕ六元系（ＭＬ为富镧混合稀土金属）在α＋β相区恒温吸氢动力学．研究结果表明，五元系贮氢合金吸氢初期受化学反应控速，后期受氢在合金氢化物中的扩散控速，动力学规律不受氢初压的影响．由于Ｃｕ的加入，六元系贮氢合金吸氢机制初期转变为β相形核长大控速，后期仍为氢在合金氢化物中的扩散控速．
The ML-Ni-Co-Mn-Al quaternary system and ML-Ni-Co-Mn-Al alloy were studied in the temperature range of 303-343K by the computer- -Cu six yuan system (ML is rich lanthanum mixed rare earth metals) in α + β phase region constant temperature hydrogen absorption kinetics. The results show that the initial hydrogen absorption of the five-element hydrogen storage alloy is controlled by the chemical reaction, and the diffusion control of the diffusion of hydrogen in the alloy hydride in the latter part of the hydrogen-absorbing alloy is not affected by the hydrogen initial pressure. Due to the addition of Cu, the hydrogen absorption mechanism of the 6-series hydrogen storage alloy is initially changed to the β-phase nucleation and growth control speed, and the latter is still the hydrogen diffusion control speed in the alloy hydride.
