摘要： The plateau region of P-C-T isotherm of a hydrogen absorbing alloy between the .alpha. phase region and .beta. phase region thereof is expressed by a normal cumulative distribution function wherein hydrogen content X is taken as frequency and the logarithm of equilibrium hydrogen pressure as a random variable. Parameters such as standard deviation .sigma. of the function are determined by numerical analysis based on measured data as to the equilibrium hydrogen pressure and hydrogen content of the plateau region of the alloy to be evaluated. Whether the equilibrium characteristics of the alloy are acceptable is determined using the parameters as evaluation criteria.
