摘要
将平面导体的镜象法运用到平面理想导体表面上有一层厚度为ｄ的电介质薄膜的情况，计算表明高平面导体距离为ｘ３的点电荷有无穷个镜象电荷，分布在导体内的连线位置，分别位于ｘ３－２ｄ、ｘ３、ｘ３＋２ｄ、ｘ３＋４ｄ等距离．
Image method is applied to a Planar ideal conductor covered with a thin dielectric film of thickness d.The calculation shows that the images of a point charge at a distance x from the conductor surface are located inside the conductor at the distances of x-2d、x、x+2d、x + 4d etc.
