随机误差统计规律研究实验的误差探讨

The Studies of the Error in the Experiment about Random Error Statistical Regularity

随机误差统计规律研究实验是《大学物理实验》课程中的重要实验之一。光电门装置的使用,使该实验的测量精度得到了很大的提高,同时也缩短了实验时间,但实验过程中出现的由于单摆的异常摆动等情况所引入的随机误差却并没有因此而得到很好的避免或减小。本文采用双线摆装置、狭缝装置和三角锥装置在一定程度上减小了测量结果的不确定度,提高了该实验的测量精度。

The experiment about random error statistical regularity is an important experiment in the 《Experiment of College Physics》. With the application of opto-electrical switch,the accuracy of measurement of the experiment is improved ,and the time of experiment is retrenched. According to characteristics of experiment,it is found that the main error of random error is come from the mode of single pendulum＇s swing,the accuracy of the experimen apparatus and person＇s reaction time. To counter these case,some measures are put forward,and then the accuracy of measurement is improved.
