摘　　要：基于网络图论的观点,对含有受控器件的线性网络构建了数学模型,给出全网电气参量的显函数描述关系;采用参量析出法,对电子线路的模型进行求解,使网络分析解析化,为计算机辅助分析与设计奠定了基础。采用节点导纳矩阵的方法,依据电子线路的特点,推导出定量计算电子线路中稳压电源的稳压系数、输出电阻的解析式,从而定性和定量地分析了电子线路参数变化和电路结构的改变对稳压电源性能指标的影响。In this paper,based on the view point of network graph theory, we build the mathematics model of linear net- work which contains controlled devices. Then,the explicit function descriptive relationships of the electric parameter which belong to the whole network are given out. Using the parameter separating out method, we resolve the problems of the electronic circuit model. As a result, we make the network analysis systematically and build the foundation for the computer analyzing and designing. According to the characteristics of electronic circuits, a node- matrix analytical method is used to deduce the analytic equations. These equations are used to computing the constant - voltage coefficient, the output resistance of the constant - volt- age source. Furthermore, we analyze the performance alternation of the constant- voltage source caused by the changes of circuits＇ parameters and structure qualitatively and quantitatively.
