| 摘 要： | 推导了周期测量精度对转动惯量误差影响的准确计算公式,指出了文献1]给出的转动惯量相对误差计算公式是在极特殊条件下得到的,且只能给出误差的最小值,因此不宜作为惯量测量误差的计算依据。文中给出误差计算值,比用文献1]公式计算值更符合实验测量结果。

| Abstract: | Exact formula about how the accuracy of Periodic measurement affect the moment of inertia is deduced, Pointed out that literature gives the relative error of inertia formula is obtained under very special conditions, and can only give the minimum error.Therefore, measurement error should not be used as the basis for calculating. Error of the calculated values given in the text is more in line with experimental results than the values calculated in Literature . |
