本文利用电感耦合等离子体原子发射光谱（ＩＣＰ－ＡＥＳ）多色仪的扫描功能，用Ｃ语言编制了Ｋａｌｍａｎ滤波程序软件包。用该软件包对铁基体中２６种痕量元素进行了回收率试验，并对标准碳素钢样中１３种痕量元素进行了测定，结果表明Ｋａｌｍａｎ滤波完全适用于复杂谱线基体中的多种元素同时分析。
In this paper, Kalman filtering program package is compiled by C language using the scanning function of inductively coupled plasma atomic emission spectrometry (ICP-AES) polychromator. The software was used to test the recovery of 26 trace elements in iron matrix and the determination of 13 trace elements in standard carbon steel samples. The results show that Kalman filter is suitable for multi-line matrix Simultaneous analysis of species.
