摘　　要：在一般电路仿真系统中,常常主要考虑仿真对象的主要因素,忽略次要因素,同样的元件用相同的仿真模型。然而,同样的两个元件其性能和参数不可能完全一样,在某些情况下,极细微的差异可能导致结果不同、甚至完全相反;就是说,在某些情况下同样的元件不能用相同的仿真模型,而必须用不同的仿真模型。该文以MULTISIM9.0仿真软件对RS触发器和主从JK触发器进行的仿真为例,分析了产生问题的原因,提出了在特殊的情况下,某些细微因素可能是决定因素,系统建模不能完全忽视一些看似很细微的因素的观点。In most systems of simulation circuits, the main factors are often concerned but the secondary factors are ignored. So the same components are often simulated with the same models. However, the parameters of the same components may not be entirely same; a slight difference will cause different even contrary result. So the same com- ponents can not be simulated with same models, which must be simulated with different models. This paper analyzes several digital circuits and the reasons of the questions by means of simulation with MULTISIMg. 0, and points out a viewpoint that some slight factors may be the key factors in some special circumstances and the slight factors can not be ignored.
