摘　　要：在用单摆测重力加速度的实验中,为了能够快速得到实验结果的准确性,文章提出了应用origin软件给出测量过程中随机误差的表达方法,用相关系数来表示单摆法测重力加速度实验中的随机误差大小.该方法简单方便,并且能够直观地反映出实验数据的可靠性.In the experiment of measuring the acceleration of gravity using simple pendulum method,in order to be able to get the ac?curacy of the experiment result quickly,this paper comes up with an expressing method of random error in the process of measuring which uses the application software of origin because using correlation coefficient to stand for random error caused in the experiment of measur?ing acceleration of gravity which uses simple pendulum method.

关 键 词：单摆 重力加速度 随机误差 相关系数
