摘　　要：阶跃函数是一种奇异函数,它在分析动态电路过渡过程中具有重要的作用,如何定义阶跃函数是正确应用其分析动态电路的关键。目前,在一些电路分析的教科书中给出了若干互有区别的阶跃函数的定义,这给教师及学生的理解造成了困难。此文介绍了阶跃函数的一种简单定义,并通过实例说明这种定义在分析动态电路过渡过程中是正确和有效的。As one of the singular functions, step function plays an important role in the transient analysis of dynamic circuits and its definition is the key to analyze transient circuits. Nowadays, several different definitions of step function are given in the textbooks of circuit analysis, which has resulted in difficulties to the comprehension of teachers and students. This paper introduces a simple definition of step function and testifies that it is right and efficient to analyze the transition of dynamic circuits by some examples.
