摘　　要：论文依据棒-板放电间隙粒子输运方程与电场泊松方程基本原理,研究正负极性棒-板间隙电子密度分布情况,分析正负极性棒-板间隙放电的异同,建立在棒-板间隙引入空气密度和湿度等介质的计算机仿真模型与实验模型.利用comsol软件仿真了棒-板间隙放电过程验证了实验结果,并得出了随着空气密度降低湿度增加的情况下棒-板间隙放电起晕电压随之降低的结论.Build the computer simulation model,according to research the electron density between the positive polarity and negative polarity rod-plate gap analyze the different between the positive polarity and negative polarity ,and join the air density and humidity to the experiment model ,analyzing the result of the computer simulation ,the result shows that corona-inception voltage decreased with the reduce of air pressure or the increase of humidity.
