摘　　要：针对Multisim中器件从0输出状态开始仿真,仿真非对称式多谐振荡器工作波形不能形成振荡输出,提出了在仿真电路的输入端接入转换开关,仿真时先将转换开关接地使电路脱离系统设置的初始输出状态,再通过转换开关构成非对称式多谐振荡器,进行正常工作状态的仿真。特点是直观形象地描述了多谐振荡器的工作工程、解决了多谐振荡器工作波形无法用电子实验仪器进行分析验证的问题。Based on the fact that the simulation of the Multisim software from the 0 output state and the working wave of the asymmetric multivibrator can not become oscillating form,we propose to insert a changeover switch at the input end of the simulation circuit.During the simulation processes,the changeover switch is first put to earth so as to enable the system to disengage from the original output state,then we form an asymmetric multivibrator with the help of the changeover switch and simulate the normal working state.The most important character of the simulation scheme is that direct picture of the working processes of the multivibrator,and resolved the problem of analyzing the multivibrator＇s working wave by electric instruments.
