摘要
针对卡尔曼滤波法存在的问题，提出相关数据组卡尔曼滤波法。本方法可减小测量值误差对迭代运算的影响，有效地抑制了滤波数值的发散。以数值模拟体系检验本方法，当误差为±５％时，回收率为９５．５％～１０５％。以ＰＡＲ为显色剂，对锌、镉、铅三元素进行同时测定，获得了满意的结果。
This paper presents a method of Kalman filtering spectrophotometry with the associated data It can effectively reduce the influence of measuring errors on iteration and inhabit the divergence of filtering data The effectiveness of this method is identified by means of numerical simulation Consequently, when the errors rate is within 5%, the rates of recovery are 95 5% to 105% Furthermore, we have obtained more satisfactory results when we use PAR as coloring reagent and then use this method to determine Zn Cd and Pb simultaneously
