| 摘 要： | 节点电压法是分析、求解电路的最方便最快捷的方法,它所涉及的变量少、方程数少,因而被广泛采用。但它仅限于网络中均为非零阻抗支路的情况,当遇到零阻抗支路时,通常采用改进节点电压法。文章阐述了常规节点电压法和改进节点电压法的解题思路,并结合实例介绍了改进节点电压法的应用过程,对丰富课堂教学内容、开阔学生视野、激发学生的学习兴趣有一定的促进作用。

| Abstract: | The node-voltage method is the most convenient and speedy method in analyzing and resolving circuit,it involves fewer variable and equations,so it is adopted widely.But this method is only confined on the situation that there is no zero impedance branches.Coming across that there are zero impedance branches,the improved node-voltage method is adopted usually.This article expounds the resolving idea of both the conventional node-voltage method and the improved node-voltage method,and then introduces the application process of the improved node-voltage method by practical examples,so it will produce some promotive effects in enriching the content of classroom teaching,in widening the student's field of vision,in stimulating the student's studying interest. |
