摘要
对扭摆法测量刚体转动惯量的实验装置进行改进,在扭摆上加装一个圆柱形外罩,屏蔽了空气压差阻尼,保持空气黏性阻尼在测量过程恒定,提高了测量精度.
The torsional pendulum method for the experiment device measuring the moment of inertia of rigid body is improved. Adding a cylindrical casing on torsional pendulum,we find that it can not only blocked air pressure differential damping,but also keep the air viscous damping constant in the measurement process. The accuracy of measurement is improved.
