摘　　要：为解析放电等离子体形成过程,对过程参数进行优化,以低温等离子放电管作为研究对象,在常温常压下用组合式多功能光栅光谱仪对放电光进行测量,经计算机处理,可得到空气体系中放电光的近紫外段的发射光谱。通过对放电光谱的检测分析,可以察知放电等离子体形成的途径,了解各种粒子乃至电子的能量,从而可对放电管作出相应的评价。Low-temperature plasma discharge reactor has been found widely used in environmental engineering. For cutting down power consumption and raising productivity, it is essential to optimize discharge reactors. Discharge reactor supplies low-temperature plasma in which energy of electron is far higher than energy of other particles, and brings about chemical reaction. A low-temperature plasma discharge reactor was chosen as the subject of the study. The light spectrum of discharges in air at atmospheric pressure has been measured in the near-ultraviolet region. Having made an investigation on the light spectrum, we can find out about the reacting channels and detect energy of various particles or electron. So that we can make a diagnosis to the low-temperature plasma discharge reactor. This paper presents an assessing method by spectral analysis to low- temperature plasma discharge reactor.
