摘要: 结合现代教学理论,通过构建简单的物理衰减模型,从典型的简单衰减过程的视角,对RC和RL暂态过程进行了分析,并简洁明确地诠释了求解时常用的一阶线性方程的三要素法的表达式的物理含义,从而得出了比较通用且意义明确的分析和求解策略,达到了改善教学效果的目的.

关键词: 暂态过程, 衰减.

Abstract: According to the modern educational theories, a typical attenuation with a constant attenuation coef- ficient is analyzed to decipher RC and RL transient state processes, and the essence of three-factor method for the first order circuit is revealed. Consequently, an active and meaningful strategy for solving these problems is obtained and therein lies a successful method of improving the learning effect.

Key words: transient state process, attenuation
