摘　　要：含受控源电路的分析一直是电路理论教学中的难点问题,当受控源的参数发生变化时,可能会使得线性电阻电路无解、无穷多个解或使动态电路变得不稳定。本文通过计算实例分别讨论了线性电阻电路和线性二阶电路解的性质和受控源参数的关系,用Multisim仿真软件对受控源的参数进行了扫描分析,并得出了有关分析结果,体现了Multisim仿真软件在含受控源线性电路分析中的有效性,有利于加深学生对理论知识的理解。The analysis of circuit containing controlled sources is very difficult in the teaching of electric circuits theories.The change of controlled sources' parameters will maybe make linear resistive circuit's solutions nonexistent or infinite and make linear dynamic circuit unstable.In this paper,the relationship between controlled sources' parameters and property of solution of linear resistive circuits and secondorder circuits is discussed by examples.The circuits containing controlled sources are simulated using Multisim software with sweeping controlled sources'parameters and some results are also obtained.The simulative results indicate that it is effective to use Multisim software in analysis of linear circuit containing controlled sources and can help students deepen the understanding of theoretical knowledge.
