摘要
本文综述了卡尔曼滤波在多组分光度分析中的应用。通过理论分析与实验验证探讨了滤波过程的某些基本问题,如误差协方差矩阵计算的公式选择、滤波初始估计值对结果的影响、新息序列的相关性检验对结果可靠性的判别、信息量的度量与滤波过程是否达到最优及波长选择的某些关系、实验联机处理的某些问题等。
The fundamental principle and basic algorithm of Kalman filtering as applied to multicom-ponent photometric analysis are surveyed. Some aspects of the method such as the selection ofthe appropriate equation for calculating the error covariance matrix, the effect on the resultsfrom the initial values, the correlation of innovation sequence as a criterion for judging the reli-ability of the analytical results, the information gain of stepwise for indicating the stop-point orfor selecting wavelengths for measuring, and on line analysis are discussed. Several applicationexamples in organic and inorganic analysis are presented. 46 references are cited in this review.
