| 摘 要： | 从物理学的角度分析了“拍”现象的原理，讨论了拍频的变化规律，给出了调律时冠根音之间的拍频公式．指出，调律师应根据拍频能够量化的特点，通过听辨拍频，得出各音之间的频率比，按照十二平均律的频率关系，对钢琴进行调律．

| Abstract: | The principle of ＂beat＂ and the beat frequency variation are analyzed from physics aspects. A calculation formula for beat between root and top is also provided. Because beat has the feature of quantification, piano tuner can get the frequency ratio of each tune by listening to beat frequency. And on the basis of the frequency relations of twelve-tone equal temperaments, they can tune the piano. |

| Keywords: | beat frequency interval twelve-tone equal temperaments tuning |
