“转动惯量测量实验”的剖析

An Analysis of "Experiment on Measuring Turning Lnertia"

文章对一实验进行剖析,将物理实验包含的三大部分(设计、测量、结果处理)浓缩在一文中,通过具体运用实验的基本知识、方法、习惯、技能的实例,论述了实验课中,怎样着重把握物理内容和误差分析思想。同时,介绍了一种电动音叉计时法。

The purpose of this paper is to analyse a type of esperiment, and to put in a condensed form the three parts of physical esperiment: designing, surveying, and handling the results achieved. An example is presented to show how to acquire physical idea and learn to analyse errors by applying basic experimental knowledge of physics and the convevtional skill in experiments. In the meantime, the paper recommends a new way of marking and recordingg time with electric truing fork.
