大气压介质阻挡放电三种模式的电学特征

Electrical Characteristics of Three Models of Dielectric Barrier Discharges Under Atmospheric Pressure

为了解大气压介质阻挡放电3种放电模式（丝状放电、辉光放电、伪辉光放电）的电学特征，利用10～50kHz、0～20kV电源在平板电极结构上实现3种放电模式，并通过放电图片、电压电流曲线、电压一电荷李萨如图形对各放电模式进行诊断和电学特征阐述。试验证实3种放电模式确实存在且可在一定条件下相互转化。

Dielectric barrier discharge under atmospheric pressure has three models, filamentary discharges, glow discharges and pseudoglow discharges. In our experimental study, those three models are achieved in parallel electrodes with the high voltage source （10-50 kHz, 0-20 kV）. Analyzing discharging photos, voltage-current curves and voltage-charge figures, the three models are diagnosed and their respective electrical characteristics are fully demonstrated.
