摘　　要：目前高校中常用的单摆仪,存在摆线长度测量中易损坏摆线,学生难以把握摆幅和摆角调节尺度,仪器调节缺少水平仪等问题.为了解决这些问题,提出了如下设计方案,采用套筒式支架,可自由伸缩调节,扩展摆长的变化范围,更好的研究摆长与周期的关系.增加竖向刻度尺、横向刻度尺、光电门、周期测定仪、量角器及水平仪等.以期减少系统误差.By analyzing the current single pendulum in universities, it is found that it is easy to grasp the cycloid in the cycloidal length measurement. It is difficult for the students to grasp the scale of the swing and the swing angle. It needs to use the trigonometric function to calculate the relationship. Aiming at the problem, an improved scheme of the experimental instrument is proposed. The sleeve bracket is used to adjust the range of the pendulum length and to study the relationship between the pendulum length and the cycle. Increase the vertical scale,horizontal scale, photoelectric door, periodic tester, protractor and level, and so on. The improved instrument reduces system error and human error.
