刚体转动惯量实验中影响阻力矩因素研究

Factor of Influence Resistance Moment in Rotational Rigid Body Experiment

通过理论和实践,对在推导刚体转动惯量的测量公式时所采用的近似方法以及测量刚体转动惯量时由于仪器使用的选择对阻力矩带来的影响作以分析,从而总结出影响阻力矩的因素,进而指导测量,降低误差。

With the theory and experiment, the approximation used in the deduction to the result of measurement and the approximation used in the deduction to the result of measurement and the cause of influence resistance moment was analyzed in measuring the moment of inertia of rigid body. The factor was summarized. The results show that it was instructional for the experiment measure, and it ean reduce the experiment error.
