摘　　要：拍现象是一种由两个简谐振动合成产生的幅值随时间周期性变化的现象。从拍现象及其特征出发,分析拍产生的条件,并借助计算机绘图从圆频率、相位、幅度三个方面讨论影响拍的因素,为深刻理解拍现象提供了很好的可视化手段。Beat phenomenon is a phenomenon that the amplitude of two simple harmonic vibrations changes periodically with time.Starting from the beat phenomenon and its characteristics,this paper expounds the conditions of the beat,and discusses in detail the factors affecting the beat from the three aspects of circular frequency,phases and amplitudes with the help of computer graphics,which provide a good visual means of operation for a deep understanding of the beat phenomenon.

关 键 词：拍现象 圆频率 相位 振幅
