再评电磁学关于双向标量问题的分析

MORE COMMENTS ON ANALYZING TWO-WAY SCALAR PROBLEM IN ELECTROMAGNETICS

本文通过比较传统方法和规范化方法在推导电容器电流与极板电荷变化率的关系式以及动态电路微分方程的区别，说明电磁学在分析含有双向标量的问题时应该采用规范化方法，以保证分析过程的科学性及所得结论的普遍性．

Comparison between traditional method and standard method is made deriving the relation between the current and the rate of change of plate charge in capacitor and in Obtaining the differential equation of motional circuit. It is pointed out that the standard method should be used in analyzing problems involving two-way scalar in electromagnetics. The course will be more scientific in analyzing such problems, and the universality of conclusion will be greatly improved.
