摘要
本文将岭回归用于分光光度分析中的多组分同时定量,着重介绍了方法的基本原理,基本步骤和基本计算。指出了它特别适用于最小二乘估计不够理想的情况,即当吸收系数矩阵S=ε~Tε接近退化,以致使浓度值C接近不可估的病态体系。并将该法用于复方阿司匹林片中三种组分的测定,取得满意结果。
In this paper, a ridge regression method of spectrophotometry in multiwavelength is proposed. The basic principle and computing of this method applied to multicomponent analysis were discussed. This method was applied to simultaneous determination of multicomponents in aspirin compound tablet and satisfactory results were obtained. The experiment clearly indicates that ridge regression may provide a new approach to experimental measurement of multicomponent analysis computations.
