摘要

研究了单摆测重力加速度实验中角振幅的影响。结果表明，随意选取角振幅可能导致实验结果不确定性的增加，及人为的系统性偏差；在实验中，不同摆长下宜选取相同的角振幅。

Abstract:

The influence of angular amplitude in the experiment of measuring acceleration of gravity by simple pendulum is studied. The results show that arbitrary choice of angular amplitude may increase the uncertainty of experimental results and result in artificial systematic deviation. In experiments, the same angular amplitude should be chosen under different pendulum lengths.

Key words: simple pendulum angular amplitude data analysis
