探究造成蛇形摆误差的原因

Explore the Causes of Serpentine Pendulum Errors

作者与小组成员制作了一个利用摆长不同的一列单摆,在同一位置释放,使其轨迹呈现出有规律的周期变化的装置——蛇形摆。蛇形摆最主要的特征就是一旦被释放,其运动轨迹就会像蛇向前行走一样,并会在经过一定时间后,重复先前运动轨迹。本文主要对造成蛇形摆误差的原因进行分析。

the author and the members of the team made a device that used a series of simple pendulums with different pendulum lengths to release them in the same position,so that their trajectories showed regular periodic changes--snake pendulum.The main feature of a snake's pendulum is that once released,it moves forward like a snake and,over time,repeats its previous trajectory.In this paper,the cause of serpentine pendulum error is analyzed.
