【摘要】 "拍"是自然界中的一类重要现象,在生活和工业生产中都有重要的应用.本文采用旋转矢量分析法得到了合成"拍"的统一公式,并详细的讨论初相差、振幅比β和频率比δ对"拍"现象产生的影响,采用数值分析的方法验证了讨论的结果,得到了要获得明显的"拍"现象的条件为:0.33<β<3.0且0.846≤δ<1或1<δ≤1.182.更多还原

【Abstract】 Beat is a very important phenomenon of nature and is useful in industry and daily life.In this paper, thebeat phenomenon is studied with the method of rotating vector, and the effect of the frequency difference,amplituderatio and phase difference of two simple harmonic upon the beat phenomenon are analyzed in detail.In addition,theresearch finds out the range of the frequency difference and amplitude radio of two simple harmonic vibrationswhich can produce clear beat phenomena.更多还原
