静态工作点是“模拟电子技术”课程中的教学重点，也是教学难点。利用仿真Multisim 10软件，对共发射极基本放大电路进行静态仿真测试分析，使学生在基本放大电路的学习中对静态工作点的概念、静态工作点对放大电路的重要性和必要性有比较清晰正确的理解，对共发射极放大电路在不同工作情况下的特点有一个比较全面的认识。研究表明，利用Multisim 10强大的分析功能对电子电路进行计算机仿真，可以提高教学质量和教学效果。%In "analog electronic technology" course,quiescent operating point is not only the key point,but also the diffi-cult point in teaching. The common emitter basic amplifying circuit is statics simulated and analyzed by using Multisim 10 to make the students have correct understanding about the concept of the quiescent operating point and the importance and necessity of the quiescent operating point on the amplifier circuit,and fully study of the characteristics of common-emitter amplifier circuit in different working situations in the study of the basic amplifier circuit. The research shows that computer simulation of electronic circuits with Multisim 10 can improve the teaching quality and teaching effectiveness.
