摘　　要：针对传统高频电路实验中存在的问题,提出在实验教学中引入Multisim进行仿真.利用Multisim对高频电路的典型电路丙类功率放大器和负阻振荡器进行了仿真,其各项结果与理论一致,且可方便地改变电路参数,观察不同条件下电路的工作情况.虚拟实验既能降低实验成本又能使实验在时间和空间上得到有效的延伸,是传统实验的一个必要的有益补充.Aiming at the problems in traditional teaching of high frequency electric technology experiment,it presents that multisim should be applied.The class-C high-frequency resonance power amplifier,negative resistance device oscillator,which are typical circuit of high frequency electric technology,are simulated by Multisim.All of results are identical with theoretic.It is convenient to change the parameters and component of circuit,in order to observe going of circuit.The experiment which is integrated with traditional dummy experiment can do better in advance of student＇s operational and groping ability.
