分光光度法同时测定多组分体系的研究及应用进展很快。其中,计算数学同分光光度法联用则尤为人们所重视。本文提出的方法是根据多波长处多次标准加入分光光度测定所得的数据,通过矩阵运算求出复方药物中各组分的含量。作者以双组分药物——复方甲基异(口恶)唑为例,应用线性方程组求解过程的误差传递与矩阵条件数的关系,对测定所需条件的优化 The research and application of the simultaneous determination of multi-component system by spectrophotometry is progressing rapidly. Among them, the calculation of mathematics with spectrophotometry is particularly valued by people. The proposed method is based on the number of multi-wavelength standard spectrophotometry added to the data obtained by matrix calculation of the compound drug content of each component. The author takes the two-component drug compound methyl iso (oxazole) as an example, and applies the linear equations to solve the relationship between the error transfer and the matrix condition number, and optimizes the conditions required for the determination
