针对电路理论分析中元件参数变化引起的电路响应变化，利用LabVIEW软件平台自行设计了线性直流电路各种分析方法的仿真，虚拟实现了“支路电流法、回路电流法和节电点压法”的电路分析及叠加定理的仿真验证。通过自定义控件用户不但可以方便地搭建电路模型，还可通过改变控件值直接改变电路元件参数，由此产生的响应变化随即以数值、波形或表格等形式直观地显示在界面上，从而加深了对电路定理和规律的理解和掌握。

Aim at the abstract circuit response caused by the parameter variation of the com-ponents of the circuit theoretical analysis , this paper designed a simulation of the linear DC circuit analysis method on the LabVIEW platform , accomplishing the analysis and the dem-onstration of the branch current method , cyclic current method and node voltage method in simulation .Through the custom control , the user could make up circuit model conveniently , but also could change the parameter of the component by changing the value of the control and thus the respective change would be presented on the window in the form of values , waveforms or a table.As a result, the students’ understanding to the circuit analyzing meth-od was enhanced .
