| 摘 要： | 在外加交流高压的条件下,多孔陶瓷内可以产生稳定的大气压微放电.通过对放电的图片以及电压、电流的分析得出微放电的部分物理特性.结果显示:陶瓷微孔内的微放电并不是由陶瓷的表面放电转变而成;多孔陶瓷孔内微放电的起始放电电压随着陶瓷厚度增加而升高,而随着多孔陶瓷孔隙率的增加而降低.

| Abstract: | The microdischarges generated inside porous ceramics by AC high voltage represent a novel way to create stable atmospheric pressure plasmas.The physical characteristics of discharge in porous ceramics were investigated by photographic visualization and electrical measurements.Experimental results show that the surface discharge is not converted into pore microdischarges,and the onset voltage of pore microdischarges increases with the thickness of ceramics,while significantly decreasing with increasing porosity of ceramics. |
