摘　　要：为了解决教学中学生对三极管微变等效电路的疑惑,有必要从理论上对微变等效电路进行分析,从而消除学生的疑惑;为学习模拟电子打下良好理论基础;文章从偏微分方程出发,结合电路网络等效原理;从理论上推导出了微变等效电路的机理,实践证明有了这个作为分析作为放大电路的基础,对系统深入分析放大电路,提高学生学习的有效性有一定的借鉴作用。In order to solve the confusion of triode amplifier micro equivalent circuit in the teaching of students, it lays a good theoretical basis for learning analog electronics. This article begins from partial differential equation and combined with equivalent circuit network principle. Micro variable equivalent circuit is deduced theoretically. Practice proves with this as the basis of analyzing as amplifying circuit. It is the reference for analysing amplifier circuit systematically and to improve the effectiveness of student learning.
