摘　　要：LC振荡器是"非线性电子线路"课程的重要内容。在教学中,如何判断振荡器能否起振是一个重点内容,也是难点之一。我们针对教学过程中学生面对变化多端的电路形式,出现的困惑,提出相应的解决方案,在讲法中注重总结和提炼,分层次展开。实践表明,这样讲解符合初学者的认知规律,更利于学生掌握这一知识点。LC oscillator is one of the most important contents of Non-linear Electronic Circuit course. To judge whether the oscillator vibrates or not is an important issue. Facing varieties of circuit form, the students tend to do nothing. So to resolve the confusion from our students, a special method is introduced~ which is the way of regarding summarizing and abstracting, and the way of layered introduction. Experi- ence shows this method is not only suitable for beginners, but also can help students master this know- ledge point preferably.
