摘　　要：文章分析讨论了场域空间填充有多介质且存在3种以上介质公共点或公共线上的电磁场边值关系一般形式,就简单可解的多介质分界面与电场线重合和多介质分界面与等势面重合的特殊情况举例说明其应用.结果表明多介质公共点或公共线上的边值关系并非是简单的两、两介质分界面边值关系的组合,多介质公共点或公共线上的边值关系确有必须遵循的特殊形式.In this paper,we analyzed and discussed the general form of electromagnetic field boundary value relations on the public point or line of three or more media.We illustrated its applications by two simple solvable special examples,which are the superposition of multimedia interface with electrostatic field lines and the superposition of multi-media interface with equipotential surface.The results showed that boundary value relations on multi-media public point or line were not the simple combinations of the boundary value relations of two or more media interface,and there were special forms that must be followed.
