摘要
在动力法测量刚体转动惯量实验中,通过讨论转动角位移与时间以及计时方法之间的关系,给出了一种改进的实验方案,降低了测量的系统误差。
The relationship between time and angular displacement was discussed in rotational inertia measuring.Anexperimental method was proposed for measuring the rotational inertia of rigid body by using invariable moment.Thesystem error of the experiment was reduced.
