摘要： 近年来对于多组分混合物的同时测定已有一些报导。我们在此基础上,提出在紫外光谱的多组份体系分析中采用改进的矩阵解法,并用微型计算机进行计算,并通过对结果及适用特点等方面与其它方法作了初步比较和评述。

Abstract: Amodified matrix approach to multicomponent spectroscopic analysis has been described. This matrix is used for simultaneous determination of Aspirin, Phenacetin, and Caffeine with the ultraviolet spectrophotometry. Calibration with standard mixtures incorporates molecular interactions and nonzero intercept in the analysis matrix. This method, the Linear Programming, and the Coordinate Rotation are compared and discussed.
