Chinese Abstract

用刚体转动仪测量刚体转动惯量实验所要测量的主要物理量是时间,所测量的实验数据繁多(一次实验要测量150多个),且要求准确,并且后续的实验数据处理计算非常繁杂。本文介绍了一种测量时间、计算转动惯量数值两项工作全部由PC机来完成的新方法。从硬件和软件方面详细说明了如何用一台微机实现对整个实验系统中所有实验进行时间量的测量和对实验数据的处理。此方法接口电路简单,时间测量准确,计算速度快,实验结果误差小,而且易于推广。

English Abstract

In the experiment of measuring moment of inertia using rigid body instrument, time is the main datum, which is not only measured many times (more than 150 times in one experiment), but also needs to be precise. What's more, the data disposing is very complex. This paper introduced a new way on how to measure time and dispose data in the whole experiment system with only one computer. The interface circuit is simple, time can be measured exactly, and data can be disposed quickly with less error. This method can be extended easily.
