摘要
介绍电磁打点计时器的新的实验方案,用来演示受迫振动和共振现象,演示波的传播、干涉、衍射和驻波等实验现象;还介绍利用电磁打点计时器制作频闪光源的简单方法,使被淘汰的老仪器焕发新的生机。
The paper introduces the new experimental design of electromagnetic ticker timer to demonstrate the phenomena of driven oscillations and resonance,wave diffusion, interference, diffraction and stationary wave. In addition, it introduces how to produce multi-flash light by employing electromagnetic ticker timer to make obsolete equipment full of vitality.
