The streamer evolution of three-electrode pulsed surface dielectric barrier discharge (SDBD) in atmospheric air is studied with basic morphologic features, electrical characteristics and numerical simulation. Time resolved ICCD images demonstrate that besides the primary and secondary reverse streamers, a novel discharge mode-transitional streamer is also responsible for sustaining the streamer development in the three-electrode pulsed SDBD, which is different from the streamer mechanism in traditional two-electrode pulsed SDBD. Moreover, the discharge mode transition from the primary streamer to the transitional streamer is observed in a relative narrow discharge gap of 5 mm, while a relative large discharge gap of 19 mm results in a new phenomenon in which the primary streamer transits to the secondary reverse streamer without the process of transitional streamer. To determine the deposited energy of each streamer phase, an equivalent circuit model is built and it shows that t...

三电极脉冲表面介电势垒放电的演变：主拖缆，过渡拖缆和次级反向拖缆

通过基本的形态学特征，电学特性和数值模拟研究了大气中三电极脉冲表面介电势垒放电（SDBD）的流光演化。时间分辨的ICCD图像表明，除了一级和二级反向拖缆外，新型放电模式过渡拖缆还负责维持三电极脉冲SDBD中的拖缆发展，这与传统的两电极脉冲拖缆机制不同。 SDBD。此外，在5mm的较窄放电间隙中观察到了从主拖缆到过渡拖缆的放电模式过渡，而19 mm的相对较大的放电间隙会导致一种新现象，在这种现象中，主拖缆过渡到次级反向拖缆，而没有过渡拖缆的过程。为了确定每个拖缆相的沉积能量，建立了等效电路模型，该模型显示出...
