三线摆测量刚体转动惯量及其误差分析

摘要

本文研究了三线摆法测量刚体转动惯量的误差影响因素并对误差的来源和原因进行了分析，在此基础上对实验操作提出了一些改进的方法，以提高实验的精度。%In this paper, the rotating inertias of rigid body such as the cylindrical and the ring are measured by three wire pendulum and their experimental error sources are analyzed. Several meth-ods have been put forward to improve the precision of the experi-ment.
