To cause beating by superposing waves of different frequencies .

振动叠加不同频率的波以产生拍差，拍音。

When they do so , the pairs start behaving like a single particle , superposing proclivities and all .

一旦形成电子对，两个电子便表现得如同一个粒子，包括它们的叠加倾向等等。

Methods by utilizing the principle of superposing states in quantum mechanics and the general theory of multimode squeezing states , the quantum fluctuation of the general both electronic and magnetic field component were figured .
