【摘要】 通过研究AB₅型稀土贮氢化合物的平衡氢压和晶胞体积间的关系,建立了估算该类化合物平衡氢压的数学模型,并编制HVP计算机软件,该软件能通过AB₅型金属间化合物的组成估算其晶胞体积,并由平衡氢压与晶胞体积的关系,求得25℃下该化合物的平衡氢压,再根据平衡氢压与温度的关系算出不同温度下的平衡压力.更多还原

【Abstract】 A model for predicting the equilibrium hydrogen pressure PH2 of AB5-typed rare earth compounds was established based on the study of the relationship between PH., and their cell volumes. A software based on this model was developed. It includes the estimation of cell volume from the atom volumes of its constituents and the prediction of PH, at 25C PH2 at other temperature can be derived from the value at 25C.更多还原
