摘　　要：本文提出了一种基于电阻等效分解的分析方法。对电路中的某一电阻支路,可以对支路两端之间的某一点,假定其电压为已知值,从而可以使该点与电路中电压为这一已知值的节点相连,等效地改变电路的拓扑结构,以达到简化电路分析的目的。以密勒定理的证明、T形反馈放大器以及非平衡电桥的分析为例,说明了本文方法的适用性。本文的讨论可供讲授电路理论课程的教师参考。An analysis method based on equivalent decomposition of resistors is proposed.For a resistor branch in the circuit,it is possible to assume the voltage of a point between the two terminals of the branch to be a known value,so that the point can be connected to the node in the circuit whose node voltage equals this known value.This equivalent transformation can effectively change the circuit topology to achieve the purpose of simplifying circuit analysis.The applicability of the method is illustrated by the proof of Miller theorem,the analysis of T-shaped feedback amplifier and unbalanced bridge.The analysis results are helpful for the teaching of circuits.
