| 摘 要： | 为更深入地认识电晕放电低温等离子体中自由基的生成机理，以发射光谱测量为基础并结合背景气体淬灭率影响，研究了常压下喷嘴-平板电晕自由基簇射过程中放电参数、背景气体、电极气成分等因素对OH(A2S+→X2p, 0-0)发光的影响。结果表明：在放电参数影响中，放电电压及放电电流都会影响OH生成量，OH发光随功率增加而大大增强；在加湿氮气直流电晕放电中有明显的OH(A2S+→X2p, 0-0)光谱存在，但加湿空气条件下OH生成较少；载气增湿后OH生成量明显增多，而Ar和O2的存在分别增强和减弱了OH(A2S+→X2p, 0-0)发光，可能的原因是这两种物质影响了放电和OH(A2S+)的淬灭。

| Abstract: | In order to get extensive knowledge of radical production in a corona induced non-thermal plasma, the effect of discharge parameter, gas condition on emission intensity of OH(A2S+→X2P, 0-0) in a nozzle-to-plate corona radical shower system are experimentally investigated using emission spectroscopy considering the collisional quenching rate. The results are that: both discharge voltage and current have direct influence on OH emission, OH production increases as discharge power rises; remarkable emission spectrum of OH(A2S+→X2P, 0-0) is detected in N2 DC corona discharge, but few OH radicals exist in air discharge; humidification of electrode gas can enhance the OH emission, and the existence of Ar increases the OH emission, while O2 may reduce the OH emission, the possible reason is th |
