“电路”课程与“电磁场”课程的联系

本文探索了电路理论和电磁场理论之间的对应关系和内在联系。我们在集总假设的基础上,首先讨论了电路理论中的基本量与电磁场理论基本量之间的对应关系,讨论了电路理论中的两类约束(即元件约束和拓扑约束)与电磁场基本规律的内在关系。笔者总结了电路理论和电磁场理论在实际应用中的区别和联系。这些关系可以帮助学生从不同角度理解和学习两门课程中的相关知识。

Relations between Electric Circuit and Electromagnetic Field Courses

The inner relationships between the electric circuit theory and the electromagnetic field theory are explored. Based on the lumped parameter model, the corresponding relations between the fundamental quantity of the electric circuit and electromagnetic field theory are studied at the beginning, ant then the inner links between the basic law of electromagnetic filed theory and the two types of constraints in electric circuit theory, which is the element constrains and the topological constraints, are studied. The difference and the connection between the Electric Circuit course and the Electromagnetic Field course are discussed at last. The relations can help the student to understand the two courses at different view point.
