the rea- son that caused the characteristic of the Beat phenomenon are analyzed. Then the
amplitude and the phase position of the beat phenomenon are discussed in detail. Finally， the
phase jump is also shown by the rotating vector method
clearly. The method describing the beat phenomenon in this paper makes the model of the beat
phenomenon so visu-al and intuitive that one can understand it very easily.
Key words： beat phenomenon; rotating vector; period; intuition
