摘　　要：本文研究了放大电路的节点数一定时,若在i、j、k三节点间插入一线性无独立源的三端网络时,放大电路低频小信号时动态性能的解析解法。给出了当三端网络分别为晶体三极管、场效应管和线性集成电路时,计算放大电路的电压放大倍数、输入电阻和输出电阻的解析表达式。The analytic calculation for dynamic properties of amplification circuit was studied in the paper under the conditions that the number of the nodes of amplification circuit remains unchanged and a linear, non-inde-pendent source, three-terminal network is inserted to the amplification circuit at the nodes i. j. k. And the paper put forward the analytic expressions for calculating the voltage amplification, the input resistance, and the output resistance of the amplification circuit, when the three-ter minal network is respectively a transistor, FET and the linear integrated circuit.
