摘　　要：采用偏最小二乘法及导数偏最小二乘法对一含有三种稀土与间乙酰偶氮氯磷的混和体系光谱进行剖析 ,结果表明偏最小二乘法及导数偏最小二乘法均适合多组份分析。在本体系中 ,因含有基体干扰 ,导数偏最小二乘法其定量、定性分析略优于偏最小二乘法。Partial Least Square regression (PLS) and Derivative Partial Least Square regression (DPLS) were suggested for analyzing multicomponent system containing three rare earth elements and a sensitive color development reagent, m-acetyl chlorophosphonazo. The results show that both PLS and DPLS are effective in analyzing multicomponent system. In comparison with PLS, DPLS is more effective than PLS while the possible matrix exists in this system.
