摘要: 将模糊聚类分析与因子分析相结合,对地质样品中吸收光谱严重重叠的稀土多组份体系进行解析,较好地解决了计算光度分析中校准模型的优化问题。对数据库的建立、聚类参数选择等问题进行了讨论。对地质样品中15个稀土元素进行了同时测定,标准偏差小于1.2。

Abstract: Fuzzy cluster has been applied to factor the analysis spectrophotometry for resolving the optimized problem of calibration model. The precision of calculated concentration has been raised apparently,For realizing the process automation of optimizingcalibration model the data-base has been set and the cluster parameters have been selected.Fifteen rare earth elements in geologic samples have been determined by this method. The relative standard deviation for 15 REEs are 0-3.85%, respectively.
