摘　　要：以节点电压为解变量的分析方法称为节点分析法。节点分析法作为分析线性电路的基本方法,常用于解决独立节点数少于网孔数的电路问题。笔者在教学过程中发现,应用此种方法分析电路问题时,常会遇到本文所述的三种情况。显然,三种情况的正确处理,是节点分析法应用的关键。本文力图通过具体实例归纳出这几类问题的解决方法和技巧,给学生指明解决此类问题的方向,以期达到掌握节点分析法(观察法)解决线性电路问题的目的。The analysis of taking the knot voltage as the undoing variable is call knot analysis, which is considered to the basic method in analyzing the linear circuit, and often used in solving the circuit problem of independent knots less than net holes. During the teaching, the writers found that applying this method to analyze the circuit problem often meet with three kinds of situation mentioned in this article. Obviously, the correct dealing with of these situations is the key in application of knot analysis. This article tries to deduce the solving methods and techniques of the problem by examples, giving the students direction in solving this kind of question, in order to reach the aim of how to apply this method to solve the linear circuit problem.
