【摘要】 对无理数e在电路分析中出现的几个典型例子作了分析讨论,明确指出:由1/e决定的特征常数可以在时间分布上和空间分布上,把一个按指数规律非均匀变化的问题,用一个等效的均匀变化的问题来表示;可以反映初始变化率与最终稳定值之间的联系;可以更深刻地反映某些物理过程的本质特征.更多还原

【Abstract】 This paper analyzes and discusses the physical meaning of irrational number e that appear in several representatives of circuit analyzing. It points out definitely that, the character constant decided by 1/e can express a problem odd-changed by index-rule as a even-changed equivalent, and reflect relation between original change-rates and steady values, and reveal the essence character of some physical process more profoundly.更多还原
