放大电路反馈类型教学之我见

反馈类型的分析判断是放大电路中的重要问题，也是教学中的难点问题之一．笔者从多年的教学实践中体会到，单纯按现行的各种教科书所叙述的方法去讲解分析，学生的认识较易发生混乱现象．本文从电路的结构实质出发，提出一些新的分析方法，使得叙述过程更为准确科学，理解起来也更为简单明了．

On the Teaching of Feedback Types of Amplifier-circuit

Analysing and judging the feedback types is important in the teaching of amplifier circuit and which is also one of the difficulties. The autor of this article found in years teaching that the students would misunderstand while do explaining and analysing according to the teaching methods of the nowadays text books. This article advances some new analysing methods from the construction of the electronic circuit and make the explaining scientific and easier to understand.
