| 摘 要： | 对传统单摆装置进行改进,在摆球上安装小金属探针,用软导线做摆线,在单摆下方放置带电水槽,使单摆摆动时探针在水面划动,将振动量转化为电位量,实现了单摆振动的实时测量.

| Abstract: | The usual pendulum is improved by installing a small metal probe under the bob and using soft wire to suspend the bob over a water trough.The probe moves on the water's surface when the pendulum swing and the vibration can be transformed into potential changes.The vibration of a simple pendulum is measured in realtime. |

| Keywords: | simple pendulum potential sensor real-time measurement |
