| 摘 要： | 合金中的常量成分的分析多有杉湿法化学法进行滴定分析或重量法分析，分析方法复杂、周期长。高频电感耦合等离子体发射光谱（ICP－AES）具有分析速度快、线性范围宽、能同时分析的特点，进一步改善其精密度，可应用于合金常量含量元素分析。本文用内标法改善ICP-AES分析结果的精密度，对比了用与不同内标法的结果，并测定了标准样品的常量成分，分析了内标元素的加入对结果的影响。

| Abstract: | Element concentration in alloy is normally determined by titration,which is boring and expensive.ICP AES method is characterized by quick analysis,broad linear range and simultaneous analysis ability,so it will be employed to determine element concentration in alloy if its accuracy is improved.In this paper,the accuracy of ICP AES analysis is improved by inner calibration,and its analysis results are compared with that of no inner calibration.Examination results of standard samples indicate the ICP AES method is simple and reliable. |
