沿面放电相互作用形成的超四边气体放电斑图
|
摘要
在介质阻挡放电中首次发现了由沿面放电相互排斥而形成的超四边形斑图,该斑图是由亮点、暗点、亮线组成的.用普通相机对该斑图进行短曝光拍摄,发现暗点是由四个小点组成的.用高速录像机对斑图进行曝光时间为20μs的拍摄,发现暗点是由沿面放电的相互排斥形成的,亮点是体放电.用逐渐增加高速录相机曝光时间的方法对斑图进行拍摄,结果发现,亮线是沿面放电在长时间下叠加而成的.对斑图的亮暗点的光强作了对比,发现亮点和暗点的光强之比约为10.用光电倍增管对斑图进行光信号的测量发现亮点在每半周期内进行多次放电,其中仅有一次在电压的下降沿,也反映出暗点和亮线的放电模式与亮点不一样.最后通过光谱的测量表明:亮点与亮线和暗点有不同的等离子体参数,证实亮点和暗点是不同的放电模式.最后采用壁电荷理论对斑图的形成进行了解释.
We report on a square super-lattice pattern by interaction of surface discharge with the applied voltage increasing in a dielectric barrier discharge system. The pattern consists of bright spots, bright lines, and dim spots. The spatio-temporal dynamics of the pattern is studied by photomultiplier(PMT), high speed video camera and normal camera. Results show that the bright spots discharge several times during each half cycle and they are formed by volume discharge(VD), bright line was formed by superposition of the surface discharges(SDs) over a long period of time, and the dim spots are consist of four small spots. The dim spots are formed by the repulsion of SDs. The light intensity of the bright and dim spots of the patch was compared and it was found that the ratio of the light intensity of the bright spot to the dark spot was about10. The measurement of the emission spectroscopy show the parameters of the bright spots are different from that of the bright lines and dim spots, the discharge type of bright spots an dim spots is different, and reflects that the dim spots are formed by the interaction of SDs. The formation of the pattern is explained by the wall charge theory.
