摘要： 本文基于残差双线性(RBL)的原理并结合数值遗传算法,充分利用这一信息,把pH分布－光谱两维信息引入灰色体系的定量分析中.结果表明,对于背景与待测物波谱严重重叠的体系,本法对待测组分预报有较高的准确度.

关键词: pH分布-光谱, 灰色体系, 数值遗传算法, 残差双线性

Abstract: The differences among components were increased because each component appears to be several species in an acid-base mixture.Based on the thesis of RBL, it has been achieved to use this information and introduce pHdistribution-spectra information into quantitative analysis of gray system by combining numeric genetic algorithm.The result shows that for gray systems which the spectra of background and analytes severely overlaps the prediction accuracy for analytes is higher.
