本文研究了露天时变脉冲介质阻挡放电，用简单的电路计算击穿时的折合电场。在该计算中，对放电击穿前介质表面积累的电荷进行积分，以测量间隙电压和折合电场。实验结果表明，在脉冲放电的情况下，脉冲击穿时的间隙电压随间隙的减小呈帕氏曲线变化。用Boltzmann方程求解得到的模拟结果表明，电子能量分布随间隙电压和约化电场的变化而变化。我们还得出结论，脉冲上升时间在决定折合电场，最终决定电子能量方面起着重要的作用。
Time-variable pulsed dielectric barrier discharges in open air have been investigated to calculate the reduced electric field at breakdown using a simple electrical circuit. In this calculation, charges accumulated on the dielectric surface before discharge breakdown, were integrated to measure gap voltage and reduced electric field. Experimental result showed that in the case of pulse discharge, the gap voltage at pulsed breakdown experimentally showed a Paschen curve with decreasing gap distance. The simulation result obtained using the Boltzmann equation solver shows that the electron energy distribution changed with gap voltage and reduced electric field. We also conclude that pulse rise time plays an important role in determining reduced electric field, and finally electron energy.
