| 摘 要： | 研究了偶氮氯磷－ｍＡ作显色剂，采用全光谱技术（付立叶域主组份分析）同时测定钐和钇。设计了两个名为ＳＰＡＦＡ和ＳＰＦＰＣＡ的程序来进行计算。根据八个误差函数来推断因子数目。实验结果显示，本法对严重重叠的光谱是令人满意的。

| Abstract: | With a full spectrum technique,the principal component analysis in the fourier domain (FPCA) was studied for simultaneous determination of samarium and yttrium by chlorophosphonazo mA.Two computational programs called SPAFA and SPFPCA were designed to perform the calculations.Eight error functions were calculated for deducing the number of facotrs.Experimental results showed that these methods are successful even where there was severe overlap of spectra. |
