补偿原理在电路定理教学中的应用

Application of Using Compensation Principle in Circuit Theorems Teaching

由于在《电路》教材中没有提到补偿原理,因此本文首先给出它的简易图解证明,然后通过教材习题中一道典型的算例,详细说明了补偿原理在电路定理教学中的应用。为便于比较,本文给出了两种不同的解法。结果表明,补偿原理对此类相似的参数摄动问题较其它定理有明显的优势,具有明显的物理意义,是一种优选方法。

Simple proof of compensation principle, which is not mentioned in the textbook, is given in this paper. Then application of using compensation principle in circuit theorems teaching is discussed in detail by the solving of a typical exercise in the textbook. For the convenience of comparison, two solutions of the problem are given. The result shows that compensation principle has the significant advantage and physical meaning and it can be applied more effectively compared with other theorems for solving perturbation problem.
