摘要
本文叙述用示波器显示来演示受迫振动的实验装置 ,可直观地向学生展示受迫振动的幅频特性和相频特性 .
This paper introduces a new installation, with which several forced vibration can be demonstrated. The students can directly view the characteristics of amplitude-frequency and phase-frequency by watching the screen of an oscilloscope, and understand the relationship of the vibrations easily.
