摘　　要：采用电子碰撞理论计算了点 面式高压脉冲电晕放电过程中的臭氧产生速率. 研究发现, 臭氧形成速率是电场中能量大于等于6 0eV的电子形成速率的2倍. 脉冲电压峰值和放电频率与臭氧生成速率均几乎有线性关系. 放电电极直径比电极间距对臭氧生成速率的影响更加显著.The formation rate of ozone due to the point-to-plate pulsed high-voltage corona discharge was calculated with electronic collision theory. Investigation showed that the ozone formation rate was twice as that of the high-energy electron of higher than 6.0eV. The ozone formation rate increased linearly with increasing pulsed peak voltage and discharge frequency. The effect of the discharge electrode diameter on the ozone formation rate was greater than that of the point-to-plate distance of the two electrodes on the ozone formation rate.
