分光光度法多组份体系的同时测定——阻尼最小二乘法

Simultaneously Spectrophotometric Analysis of Multicomponent Systems——Damper Least Squares Method

本文提出测定多组分体系的阻尼最小二乘法。引入阻尼因子,可改善高阶最小二乘法方程系数矩阵的病态程度。并对PAR-Cu,Zn,Cd,Co,Ni体系进行测定,其结果较满意。

A damper least squares method for simultaneous determination of multicomponent systems is presented. The method can improve the ill-condition property of normal equation such that the systems of more than three components may be determined, With this method, PAR-Cu; Zn; Cd; Co; Ni are determined satisfactorily.
