摘 要: 利用扭摆可以测量物体的转动惯量 .扭摆实验是大学理工科常做的普通物理实验之一 .如何确定测量方案是学生做实验时经常提出的问题 ,一些实验参数如圆盘的摆幅多大 ?空气的阻尼影响多少等等是值得探讨的 ,而《普通物理实验》教材在该方面也讨论得比较少 ,甚至有些教材给出一些不恰当的参数 ,对此 ,本文给予讨论 。 Experiments on torsion pendulum in ordinary physics are deviced for science students at university.A torsion pendulum can be applied in measuring the rotating moment of inertia of an object.The measuring method for the experiment is worth discussing,for the students tend to raise the question of how to decide the indices for the experiment,such as the arc length of the swinging cone and the strength of the resistance through the air.College textbook“Experiments for Ordinary Physics”presents very little discussion in this respect and some indices provided are found to be inappropriate.The content in this thesis may serve as references in conducting the experiment.
