摘要

用粒子网格法模拟了负流光在低压氧条件下两个球形电极间的传播。在大部分气体中，电离、电子附着和离子的复合都被考虑过。在阴极，二次电子被正离子和光子的冲击释放出来。沿球体中心连接线计算了电场和粒子密度。研究了增加压力对流光传播的影响。

Streamer propagation in oxygen between spherical electrodes: a numerical simulation with a particle method

The propagation of a negative streamer between two spherical electrodes in low pressure oxygen is simulated by means of a particle-mesh method. In the bulk of the gas, ionization, electron attachment and recombination of ions have been considered. At the cathode, secondary electrons are released by impact of positive ions and photons. The electric field and the particle densities have been computed along the line joining the centers of the spheres. The effect of increasing pressure on the propagation of the streamer has been investigated.
