摘　　要：镜像法是静电场边值问题中的重要方法,是电磁场教学中的重点之一。本文对球面的镜像法展开讨论,通过教学中得到的反馈和总结,以唯一性定理为基础,使用待定系数法,重新推导了球面镜像法的镜像电荷及其摆放位置。本文推导使用更一般的假设,推导过程更详细,可以作为"电磁场与电磁波"课程的教师和学习者有益的参考。Mirror method is an important method in boundary value problems of electrostatic field and one of the key teaching points in electromagnetic fields. The spherical mirror method is discussed based on feedback and conclusion during teaching process. Method of undeterminated coefficients is introduced according to uniqueness theorem and the position and quantity of electric charge of the image charge are deduced. Compared to derivation in current teaching materials,contents in this paper is proposed in thorough details. The derivation in this paper can be used by teachers and learners as references when performing relating courses.
