摘　　要：根据一个均匀极化的一般椭球形电介质表面的极化电荷的分布规律与一个处在均匀外电场中具有相同形状的导体椭球表面上感应电荷的分布规律的相似性,通过先求出均匀极化椭球表面上极化电荷的分布规律,然后用类比的方法给出了一个处在均匀外电场中具有相同形状的一般椭球形导体表面上电荷的分布规律。Based on the similarity between the distribution of induced charges on the surface of uniformly polarized dielectric ellipsoid and that on a conducting ellipsoid in external electric field with the same shape, we give the distribution of the charges on the surface of a conducting ellipsoid in external electric field through their analog, after achieving the distribution of induced charges on the surface of uniformly polarized ellipsoid with the same shape.
