Though an increase of the electrode width considerably improves the discharge characteristics,it inversely affects SM-PDP performance because of the increase of both the induction between neighboring electrodes and the output power.
SM PDP中可以通过改变电极宽度 ,使放电空间的等位面沿电极增加的方向扩展 ,在等位面扩展的区域电场得到增强 ,从而改善SM PDP的放电性能。
The influences of exposed electrode width,encapsulated electrode width and gap width between electrodes on discharge process and effect were studied.
结果表明,放电过程可能存在非线性作用,缩短暴露电极宽度、减小电极间隙能够提高放电效果,但电极最好不要重叠,电极间隙有一个最佳值;植入电极宽度存在最大值,超过该值会降低放电效果。
