根据等离子体的流体方程提出了脉冲电晕放电中流注形成和传播的数学模型，导出了流注空间电荷电场的普遍积分表达式．用Ｆｌｕｘ－ＣｏｒｒｅｃｔｅｄＴｒａｎｓｐｏｒｔ（ＦＣＴ）算法，就实验中所用的超窄脉冲电压波形对该模型进行了数值求解，得到了带电粒子密度、电场和电子温度等参量沿流注发展轴线上的时空分布
According to the plasma equation of fluid, a mathematic model of the formation and propagation of effusion in a pulsed corona discharge is proposed, and the general integral expression of the electric field in the effusion space is deduced. The Flux-CorrectedTransport (FCT) algorithm was used to numerically solve this model with the ultra-narrow pulse voltage waveform used in the experiment. The distributions of the charged particles’ density, electric field and electron temperature along the axis of spurt were obtained
