摘　　要：基于Maxwell方程组的电磁场理论(“场”理论)和基于基尔霍夫定律的集总参数电路理论,以及基于电报方程的分布参数电路理论(“路”理论)是求解电磁场问题的主要理论工具。文中详细讨论了这三种理论间的关系,给出了应用“路”理论简化电磁场问题分析的几个典型例子,并讨论了应用“路”理论分析“场”问题的局限性和相关注意事项。Electromagnetic field theory, lumped-element circuit theoy and distributed circuit theory , based on maxwell＇s equations, kirchhoff＇s laws, telegrapher＇s equation respectively , are the main methods to analyze electromagnetic problems. This pa per, after analyzing the relationship between these theories , presents several examples of simplifying the analysis of electromagnet ic field problems and discusses the limitation and several important points which should be paid attention to when applying circuit theory to analyze electromagnetic field problems.
