| 摘 要： | 遗传因子分析方法（GFA）综合了遗传算法（GA）和迭代目标因子分析法（FA）的优点，不仅实现了校准模型的动态化，而且解决了多组分同时测定时收敛滞缓的问题。遗传-因子分析方法应用于15种稀土的同时测定，提高了分析结果的准确度。

| Abstract: | Genetic factor analysis(GFA) inherit the excellence of genetic algorithms(GA) and factor analysis(FA). Not only the calibration model was made dynamically, but also the creeping convergence speed was improved in multi-components simultaneous determination. Genetic factor analysis was applied to determinate 15 rare earth elements simultaneously, and the accuracy degree was increased. |
