| 摘 要： | 利用Matlab设计多次测量时间的实验，首先使倒计时钟倒数，计算机自动取倒数到零的时刻t0，同时鼠标点击“计时”按键，程序取点击时刻t1，误差为t1-t0，多次测量后可以得到随机误差的分布，实验表明，误差符合高斯分布。

| Abstract: | Designed an experiment to invest random error＇s distribution of Multiple Measurements＇ by using Matlab,let the countdown clock work,when zero appears, computer record this time to, at the same time, click the given button by mouse, computer record this time t1, the random error is t1 - t0. And random error＇s distribution can be gotten when the experimental times is large enough, the result show the random error＇s distribution meat the Gaussian distribution. |
