从微分方程的角度谈共振

摘要

本文以一道物理问题—数学摆的微小震动为例,结合质点的振动理论,建立微分方程,并且根据其解的形式,说明共振现象发生的原因。然后,针对与共振相关的生活问题和灾难问题,提出预防措施.%With the together physical problem-mathematics puts smallly to vibrate for example,combine the vibration theory that the quality orders,establishment differential equation,and explain resonance the cause of phenomenon according to the form that it solves.Then,aim at the living problem linked to resonance and disaster problem,put forward to prevent from measure.
