摘要
对刚体转动惯量测定仪进行改进,增加实验过程的砝码下落距离,以提高实验精度.与测量圆环内外半径后计算得到的转动惯量相比,改进后的实验方法测量结果精度更高.
To improve the experiment accuracy,a modification was made to the present apparatus used in measuring the rotation inertia of rigid bodies by increasing the falling distance of the weight.Compared with the rotation inertia obtained through the calculation of inner and outer radius,the improved method has a result with higher accuracy.
