本文的目的是提醒物理教育工作者注意价格低廉的家用计算机在大学物理实验室中的一个重要的新应用.用这些计算机,花很少的钱就可以建立一个具有多种用途的实验点,同使用那些昂贵的计算机一样,进行物理参数的测量和实验控制.作为一个特殊的例子,我们说明如何附加少量电路,使计算机成为一个数字电压表和脉冲计数器.一、引言最近,我们决定为物理实验室配备几台计算机,用于实验控制和数据采集.几年来,人们已经认识到了计算机在实验室中应用的重要性,但是由
The purpose of this article is to remind physi- cists to pay attention to an important new application of inexpensive home computers in college physics labs, with which it is possible to build a multi-purpose experiment site with little money As with the expensive computers, physical parameter measurements and experimental controls are taken as a special example, and we show how to attach a small amount of circuitry to make the computer a digital voltmeter and pulse counter. I. INTRODUCTION Recently we decided to experiment with physics Room equipped with several computers for experimental control and data acquisition.For several years, people have realized the importance of computers in the laboratory, but by
