用数字毫秒计时器改进刚体转动实验

The improvement for the experiment on rotation rigid body with digital millisecond timer

在刚体转动惯量测量实验中,利用数字毫秒计时器计时,改进测量角加速度的原理和方法,大大提高实验的精确度和效率。

By using the digital millisecond timer clocking and introducing a new principle and apparatus, We substantially improve the accuracy and efficiency of measuring the moment of inertia.
