叠加定理在三极管放大电路教学中的应用

Application of superposition theorem in teaching transistor amplifier circuit

在医学电子学课程教学中，三极管放大电路是重点和难点，但现有大多数教材在相关内容的呈现上存在不足，再加上医学生工科知识比较欠缺，对这部分知识的学习存在困难。将“叠加定理”融入到相关教学内容中，实践证明，可让医学生更容易学习和理解相关知识，获得良好的教学效果。

Transistor amplifier is the key and difficult points in the teaching of medical elec- tronics, however, most of the teaching materials on this content is insufficient. Meanwhile, medical students have little knowledge of engineering, so it is difficult for them to grasp the related knowledge. We introduced ＇superposition theorem＇ into the relevant teaching. Teaching practice proved that this reform made it easier for medical students to have an in-depth understanding of the content and better teaching effect was achieved.
