摘要
将多元线性回归分析，用于多组分有色金属离子ＥＤＴＡ络合物的同时光度测定，讨论了方法原理、实验条件，建立了回归方程和线性方程组．对１０个自配样和矿样进行了测定。
This article applies multiple linear regression analysis to spectrophotometry,determines various component concentration of multicomponent coloured metallic ions simultaneously,discusses method principle,regression equation and linear equation.Ten of mixed samples and mineral samples are determined and satisfactory results are obtained.
