周期运动实验仪的研制

摘要

The periodic motion is a kind of basic movement form in nature. However,it is hard to observe peri-odic motion when the stay is beyond the range of visual retention. The development of periodic motion experi-mental instrument The "slow" observation of high-speed motion is realized.%周期运动是自然界常见的基本运动形式，但在超出视觉停留范围时，直接观测周期运动(例如像转动、振动)就非常困难。周期运动实验仪的研制，实现了对高速运动的“慢速”观察。
