横波演示仪的设计与制作

Design and Production on Shear Wave Demonstrator

机械波可分为横波和纵波，在中学物理教学中横波是重点和难点，为了帮助学生更好地理解横波的形成与传播过程，基于横波的特点讨论了一种横波演示仪的设计与制作，它能够真实地演示出横波的形成与传播过程．

Tran sverse wave is a kind of typical mechanical wave, an d it is also on e of the i m portan t an d difficult points of physics teaching in middle school. In order to helping students with a better understanding of the process of formation and transmission about the transverse wave,We have discussed a kind of design and fabrication of transverse wave demonstration apparatus which is based on the characteristics of the transverse wave. It can be truly demonstrated the process of formation and transmission about the transverse wave.
