摘要
用主成份分析法研究多组份体系,用非线性迭代偏最小二乘法求出各个主成份向量,建立多组份体系分析的主成份回归分析法模型,利用该模型对未知样品进行浓度预报分析。
The principal component regression method for analysis of absorbance data and for prediction of concentrations of component in mixture is developed and studied. Two demonstrations of simultaneous spectrophotometric determination of multicomponent system by this method are given.
