摘要
使用三线摆可以测量圆环的转动惯量,但测量的物理量较多,人工处理数据比较繁琐,且容易出错。因此,本文使用Matlab软件处理数据。把测量的实验数据输入Excel表格中,引入Matlab软件中运行相关程序后可以直接得到圆环的转动惯量,以及测量的百分差和相对不确定度,处理过程快捷精确。
The rotational inertia of the circular ring can be determined with three-line pendulum method, in which many physical parameters are measured. Also the data process by hands is trivial with high error probability. Therefore,the data is processed with Matlab software. The measured data in the Excel file can be imported into and processed by the Matlab software, and then the rotational inertia of the circular ring can be obtained quickly and precisely with low percentage difference and low relative uncertainty.
