摘　　要：针对传统实验的不足,对单摆振动图像演示仪进行了改进.将光电鼠标放进泡沫摆球中,并结合C#编写了Move程序,改进后的装置可记录光电鼠标的运动轨迹,并同步显示在计算机上,实现了直观显示单摆的运动属性.Aiming at the shortcomings of traditional experiment,the vibration image demonstrator of single pendulum was improved.A photoelectric mouse was put in the pendulum ball to collect the motion trail.By using a C# ＂move＂procedure,the motion trail of single pendulum was showed on computer.Then the motion property of single pendulum was obtained intuitively.

关 键 词：单摆 光电鼠标 振动 周期
