摘要
利用复摆测量物体的转动惯量是一种重要方法,本文对复摆的转动惯量公式进行拉普拉斯变化,用能量和时间来表达转动惯量,丰富了不规则物体转动惯量的测量方法.
The moment of inertia of object can be measured by the compound pendulum. The moment of inertia is expressed by energy and time using Laplace transformation, and the measurement methods of moment of inertia of irregular objects are enriched.
