应用计算机技术来同时测定溶液中多种有色组份,其基本原理和具体算法已有不少文献报导。本文是在前人工作的基础上进一步提出,根据分光光度法测定偏差的大小对各测定点自动进行计权,将“权重法”引入到计算程序中,并对可靠性高的测定点优先使用,从而使计算最佳化。关于各测定值(M_j)的测定偏差(K_j)和权重(P_j)可由下式求得:
Application of computer technology to simultaneously determine a variety of colored components in solution, the basic principles and specific algorithms have been reported in the literature. This article is based on the work of predecessors further proposed, according to the spectrophotometric determination of the size of the deviation of the measurement points automatically weighting, the “weight method” is introduced into the calculation program, and the reliability of the measurement point priority to use , So as to optimize the calculation. The measurement deviation (K_j) and the weight (P_j) for each measured value (M_j) can be obtained from the following equation:
