教学RL 回路的暂态过程时，为了改善学生对已有知识记忆的激活和建立意义明确的关联，本文使用电路模型等效 变换和构建的方法，分别以初态和终态为参考状态，对RL 回路的全状态响应进行了分析，直观地将此暂态过程解析为: 1) 从 初态到终态的常系数衰减过程，2) 零输入响应和零状态响应的叠加. 从而实现对教学效果的提高.

Using circuit model reconstruction and equivalent transformation，the RL circuit transient process is concisely analyzed with the help of meaningful physical models. When the final and initial states are selected as the reference ones，the full state response of RL circuit is illustrated as 1) a constant coefficient decay process and 2)the superposition of the zero state and the zero input state，respectively. Meanwhile，according to the research of the modern cognitive theory，this teaching process is helpful to active the information from memory，encode information in meaningful ways，form robust knowledge，and consequently，improve the teaching effect.
