多普勒效应演示仪的设计与探讨

The Design and Discussion of Doppler Effect

本文设计了一种多普勒效应演示仪,该实验装置可以演示多普勒效应现象,通过调节第一螺杆和第二螺纹杆,可以分别演示波源运动,接收者运动,二者相对运动的多普勒效应现象。该演示仪设计简单直观、操作稳定、使用方便,易于学生了解。

In this paper,a Doppler effect demonstrator is designed,which can demonstrate the phenomenon of Doppler effect.By adjusting the first screw rod and the second screw rod,the Doppler effect phenomenon of wave source motion,receiver motion and rela⁃tive motion can be demonstrated respectively.This experimental device exhibits the follow advantages:simple and intuitive,stable oper⁃ation,convenient.Moreover,students can easily understand the acquired experimental phenomenon.
