摘　　要：实验利用光电直读发射光谱仪生产厂商提供的分析软件——类型校正程序,以AlSi工作曲线(铝中添加硅镁钛锶)为例,建立类型校正程序,来自动补偿标准样品分析结果与标准值之间的差异。在选定工作条件下,Si、Fe、Mg、Ti、Sr、Zn、Ca 7个主要元素的分析结果相对误差符合GB/T7999-2007要求,完全满足日常分析要求。减少了做漂移校正的频次,不但能节约标准样品,还可有效提高分析数据的准确度,使连续作业的分析速度明显加快。The analysis software--type correction program supplied by the manufacturer of photoelectric direct reading emission spectrometer is adopted by the test, using AlSi working curve （silicon, magnesium, strontium, titanium is added into aluminum） as an ex- ample, the type correction program is established to automatically compensate the difference between standard sample analysis result and cali- bration value. Under the selected working conditions, the relative standard deviation of the analysis results for the seven main elements ： Si , Fe, Mg, Ti, Sr, Zn, Ca can meet the requirements of GB/T7999 -2007, it can fully meet the requirements of routine analysis. This greatly reduces the frequency of drift correction ; it can save standard sample and improves the accuracy of analysis data effectively, which ac- celerate the analysis speed of the continuous operation.
