摘　　要：本文从授课内容的前后衔接及理论与实践相结合方面讨论了如何讲授格林恒等式和亥姆霍兹定理,为了加强电磁场理论与工程实践案例的充分结合,笔者将格林恒等式和亥姆霍兹定理放在镜像法之前讲授。本文以此为基础讨论了静电场、恒定电场和恒定磁场的唯一性问题,并增加了基于亥姆霍兹定理的静电屏蔽和恒定磁场屏蔽相关内容的探讨。How to teach Green identities and Helmhohz theorem is discussed in this paper from consistent of teach- ing and combination of the theory and applications of these two theories. In order to intensify the applications of vec- tor identities and to fully combine electromagnetic field theory with the electrical engineering cases, the Helmholtz theorem is combined with Green identities to be taught before the chapter of imaging method, and the problems of uniquenesses of electrostatics, static electric field and magnetostatics are discussed and the discussion of electrostat- ic shielding and magnetostatic shielding are added in this part.
