摘　　要：通过优化放电参数,分析质谱干扰,校正相对灵敏度因子(RSF),对高温合金中的氧和氮元素进行测试,并将结果与氧氮氢分析仪检测结果进行比较。结果显示,使用辉光放电质谱仪和氧氮氢分析仪测定高温合金中氧和氮元素结果的偏差分别为小于10%和小于5.0%,且结果稳定性的相对标准偏差小于5.0%。校正后的RSF值可信,测试结果稳定可靠。The accurate analysis results of determined oxygen and nitrogen elements in nickel-based superalloys by glow discharge mass spectrometry were obtained by optimizing the glow discharge pa⁃rameters,analyzing mass spectrum interference and correcting relative sensitivity factor(RSF)and comparing the results of ONH-Analyzer(LECO).Above all,equipment was operated stably,the op⁃timized test parameters were selected and the corrected RSF value was used to test the superalloy sam⁃ples.The results of oxygen and nitrogen determined by GDMS and ONH-Analyzer were compared,the deviations of the results are less than 10%and less than 5.0%respectively,and the relative stan⁃dard deviations of stability are less than 5.0%.The corrected RSF values and test results were stable and reliable.
