摘要
用三线摆测刚体转动惯量的实验条件是转动圆盘角度要小于 5°,在实验中因仪器没有配置角度的控制装置 ,因此无法准确控制角度 ,不能满足实验条件 ,造成实验结果误差增大。装上角度控制装置后 ,转动角度可精确控制小于 5°,保证了实验条件和实验结果的误差减小。
The experimental condition that moment of inertia of a rigid body is measured by means of Three Threeads Pendulum is the angle value of the upper round disc turned shiould be less then 5 degrees.However,in practical experiment Three Threads Pendulum had not been amounted an angle control device,we dominated accuratly the turned angle of the upper disc less then 5 degrees,thus providing a favorable experimental condition and reducing the measurement error of the turned angle.
