扭摆法是测量物体转动惯量的有效方法，减小误差是该实验的关键问题。本文分析了扭摆法测物体转动惯量时空气阻力引起的误差，并给出了加载重物之后扭转系数的变化及其对测量误差的影响。结果对测量精度的提高、实验方法选择和仪器研制等方面具有重要的实际意义。
扭襬法是測量物體轉動慣量的有效方法，減小誤差是該實驗的關鍵問題。本文分析瞭扭襬法測物體轉動慣量時空氣阻力引起的誤差，併給齣瞭加載重物之後扭轉繫數的變化及其對測量誤差的影響。結果對測量精度的提高、實驗方法選擇和儀器研製等方麵具有重要的實際意義。

The method of torsion pendulum is an effective method to measure rotational inertia,The most im-portant things of which is the analysis of error. The error coming from air damping is analysis in the measure-ment of inertia moment using torsion Pendulum method. It is given that the variation of the torsion constant after loading the weight and its influence on the measurement of the moment of inertia. The results have impor-tantly practical significance to improve the measurement accuracy,choosing experimental methods and develo-ping laboratory instruments.
