用自行组装的直流辉光放电原子发射光谱（ｄｃ Ｇ Ｄ Ａ Ｅ Ｓ）仪器对分析铜合金的某些基本特性进行了研究 探讨了光源放电室结构、放电气体压力、放电电压等操作参数以及试样尺寸大小对放电性能及元素谱线强度的影响，并进行了优化 考察了在不同放电气压条件下样品的溅射率和优化条件下辉光放电的稳定性最后，分析了铜合金标准样品中的 Ａｌ和 Ｍｎ，结果较满意
Some basic characteristics of the copper alloy were analyzed by self-assembled dc glow discharge atomic emission spectrometry (dcG DA E S) instrument. The effects of the structure of the discharge chamber, discharge gas pressure and discharge voltage were discussed Parameters and size of the sample on the discharge performance and elemental line intensity and optimized investigated under different discharge pressure of the sample sputtering rate and the stability of the optimization glow discharge Finally, Copper alloy standard samples of Al and Mn, the results are satisfactory
