摘要：In order to better understand the physical mechanism of sub-microsecond pulsed glow discharge with bare metal electrodes, using a one-dimensional self-consistent fluid model, the properties of the discharge at atmospheric pressure are numerically studied. The results show that, a discharge without dielectric layers, i.e. a barrier free discharge, is extinguished only with the decrease of the applied voltage. Only one positive discharge event occurs at the slope of the pulsed voltage. A stable glow of barrier free discharge can be achieved only in short durations of the pulsed voltage. The barrier free discharge always starts with a subnormal glow discharge and then evolves into a normal glow discharge. Moreover, to control the discharge stabilization better, the effects of pulse repetition frequency, pulse duration, rising (front) and falling (slope) times on the discharge characteristics are investigated systematically. It is found that the discharge is comparatively more sensitive to the repetition frequency and the pulse duration, while little affected by the rising and falling times.
