摘　　要：对照高等数学中定积分的定义,采用类比的方法,将刚体转动惯量的定义公式过渡到积分计算公式,并进一步引入计算转动惯量的"微元法",加深了学生对刚体转动惯量概念的理解程度。This paper, comparing the definition of definite integral in advanced mathematics, converts the definition formula of the rigid body rotary inertia into an integral formula via the analogy method, and introduces the infinitesimal method of calculating the rotary inertia, deepening students＇ understanding of rotary inertia.

关 键 词：刚体 转动惯量 微元法 定积分 类比
