在双通道示波器上可直观地观测拍现象，并利用拍振动曲线测量交流电的频率。
The phenomenon of beats can be observed directly on the double-channel oscillograph and the frequency of alternating current can be measured by the vibration curve of the beats.
比如，当两个相近的音符同时响起时，会有一种让声音在强弱之间振动的干涉效应，使之形成一个“拍”。
For instance, when two very similar musical notes are played together, there's an interference effect that causes the sound to wobble between loud and soft, producing "beats."
卧螺离心机是一种具有微小速差的双转子系统，它的不平衡振动信号是一个拍振。
The horizontal decanter centrifuge is a dual rotor system with small rotating speed difference, of which unbalanced vibration is a "beat" signal.
