用电脑通用计数器测定单摆摆动周期

A Determination of Vibrating Circulations of Simple Pendulum with Current Counters of Computers

介绍了在单摆测量重力加速度实验中，用MuJ-ⅡB电脑通用计数器代替秒表测定单摆摆动周期的方法。实验表明，使用计数器不仅能提高实验效率，而且实验结果更精确。

This paper introduces how the MuJ ⅡB current counters of computers replace chronographs to determine the circulations of simple pendulum vibrations during the experiment of the determination of gravity acceleration with the simple pendulum.The experiment suggests that the use of the current counters can not only enhance the experimental efficiency but also give a more accurate experimental result.
