摘要
机械波是大学物理教学中的重点内容,本文以平面简谐波为例,阐明了波动方程所描述的物理意义,讨论了介质中两点之间的相位差,并对驻波进行了分析。
The mechanical wave is emphases content in physical university course. Using the plane simple harmonic oscillation wave as an example, we clarified the physical meaning of the wave equation, discussed the phase difference between the two particles in medium, and analyzed the standing wave in this paper.
