Stabilization of the multi-pin to multi-sphere plane negative corona discharge
多针电晕增强大气压辉光放电稳定性研究

In a multi-pin to multi-sphere plane DC negative corona discharge configuration at atmospheric pressure, stable and diffuse glow discharge has been obtained. The effect of the air flow velocity, the gap distance and the electrode structure on the discharge mode transition and the stabilization of the glow discharge is investigated by means of electric measurements and emission recording. The stabilization mechanism of the glow discharge is discussed. It is found that there is a transition phase characterized by Trichel pulse with DC component between corona and glow discharge.
