摘　　要：对静电学中用电象法求解两无穷大接地金属板间楔形区域内的电场的题目,利用群论方法加以讨论,给出了可求解的条件及一般的象电荷分布.最后证明了导出此分布所用的条件是对此题应用电象法的充分必要条件.A sort of electrostatics problem that using electric image method to solve the electric field in the wedge area between two infinite earthing metal boards are discussed using group theory. The conditions under which a solution exists and a general distribution of image electric charges are given. Finally the conditions on which the deduction of the distribution is based are necessary and sufficient conditions to apply electric image method to this problem is proved.
