摘　　要：该文对电感耦合等离子体原子发射光谱法测定工业硅中铁、铝、钙元素含量的方法进行描述,系统分析不确定来源,对数据进行采集和量化,计算得出不确定度分量、合成标准不确定度、扩展不确定度。根据评定结果分析得出,标准曲线拟合中曲线变动性产生的不确定度最大。In this paper,the method of determining the content of iron,aluminum and calcium in industrial silicon by inductively coupled plasma atomic emission spectrometry is described,and the sources of uncertainty are analyzed systematically.Through data collection and quantitative calculation,the uncertainty component,composite standard uncertainty and extended uncertainty are obtained.According to the analysis of the evaluation results,it is concluded that the uncertainty caused by curve variation is the largest in standard curve fitting.
