振动、波动现象既有紧密的联系,又有本质的区别,掌握它们的联系和区别对正确把握和理解这两种运动形式以及迅速解答振动、波动的综合题有重要意义.一.机械振动和机械波的联系与区别1.从产生条件看:振动是波动的成因,波动是振动在介质中的传播,有波动必有振动,但是有振动未必有 The phenomena of vibration and fluctuation are both closely related and intrinsically different. It is important to grasp their connections and differences to correctly grasp and understand these two forms of movement and quickly answer the comprehensive questions of vibration and wave motion. I. Mechanical vibration and The connection and difference of mechanical waves 1. From the production conditions: vibration is the cause of the fluctuation, the fluctuation is the propagation of vibration in the medium, there must be vibration in the fluctuation, but the vibration may not have
