摘要
本文用改进的偏最小二乘法(PLS)对5-Br-PADAP-铁、钴、镍体系进行了研究,结果表明,该法不仅简化了计算,还可给出定性方面的信息。
A modified partial least squares method is presented. In this method, the q vectors are not scaled and only one column of concentration matrix〔C〕is analyzed at a time. By use of this method, the qualitative information can be obtained, as well as quantitative analysis of multicomponent is performed. This method is satisfactorily applied to the colour system of 5-Br-PADAP-iron, cobalt and nickel.
