摘　　要：研究了梳状电极结构对大气压表面放电的影响 ,发现频率固定时放电电流随着外加电压的增加而增加 ,而电压固定时在某个频率范围内放电电流有最大值 ;在相同的电压和频率下较宽的电极条宽可以产生较大的放电电流 ,而电极条间距对放电电流几乎没有影响 ;用整块金属板做接地电极相比于梳状接地电极可以产生较大的放电电流 ;另外 ,较厚的高压电极可以在介质板表面产生更明亮。Influence of pectinate electrode on the discharge characteristics of surface discharge in ambient environment was studied.The results show that at a given frequency,discharge currents increase with increasing voltages;and at a certain voltage,the current maximizes in some frequency range.At constant voltage and frequency,the wider the stripe width,the higher the discharge current;and the stripe to stripe separation does not affect much of the current.Discharge current of the electrode with a whole piece of metal as its ground is much higher than that of the electrode with a pectinated ground.Moreover,thicker high voltage electrode results in a brighter and wider discharge plasma on the dielectric panel.
