摘　　要：研究当有机试剂引入低功率氧屏蔽氩微波等离子体炬时对元素发射信号和等离子体参数(转动温度、激发温度、电子密度)的影响.实验结果表明,引入有机试剂可明显改变等离子体的放电特性(尤其是激发温度).与水溶液相比,有机试剂对一些常见元素的原子发射线有一定的增强作用,而对离子线则有明显抑制作用.The effects of organic reagents on the emission signals of element and plasma parameters （ rotationaltemperature, excitation temperature and electron density） when they had been introduced in the lower power argon microwave plasma torch （ArMPT-AES） were investigated. The discharge characteristics of plasma, especially excitation temperature, were evidently changed the introduction of organic reagents studied, the spectral owing to the introduction of organic reagents. With intensities of atomic emission lines were improved to some extent, but those of ion emission lines were obviously restrained.
