摘要

研究了特里谢尔脉冲放电的微观动力学和形成机理。特里谢尔脉冲放电中存在非均流瞬态效应。通过减小极限电流电阻,模拟的特里谢尔脉冲放电电流波形在质和量上与实验中的波形一致。主导正离子在不同阶段有所不同,这源于带电粒子生成和消耗主导反应的演变。正负电荷层的存在导致特里谢尔脉冲上升沿的电场衰减。特里谢尔脉冲的形成源于空间电荷密度的变化,导致空间电场和电离率的改变。

Microscopic dynamics and mechanism of Trichel pulse discharge
The microscopic dynamics and formation mechanism of Trichel pulse discharge are investigated. A nonequal current transient effect exists in the Trichel pulse discharge. By reducing the limiting current resistance, the simulated current waveforms of Trichel pulse discharge are qualitatively and quantitatively consistent with those in the experiment. The dominant positive ions vary at different stages, which originate from the evolution of dominant reactions for the generation and consumption of charged particles. The existence of positive and negative charged layers results in the attenuation of the electric field at the rising edge of the Trichel pulse. The formation of the Trichel pulse originates from the changes in spatial charge density, resulting in alterations in the spatial electric field and ionization rate.
