In addition to alternating phase difference between two aims of interferometer, the intensity of light of the interference fringes will vary in the same frequency, which is called as phase modulation.

当两相干光附加一按固定频率变化的相位差时，其干涉条纹的光强将随之交变，即为相位调制干涉。

Trans station interference is a distant interference of the same frequency in multi station microwave transmission.

越站干扰是微波多站传输中的一种同频远端干扰。

The frequency, electromagnetic, Sparks, electrostatic interference, the two sensors have two polar same signal.

频、电磁、火花、静电等干扰，则使两个感应器产生两个极性相同的信号。

As more customers sign up, service providers simply add more base-stations because all can use the same frequency without causing interference.

Moreover, since the resulting interference pattern also depends on the waves' frequency, the same array can concentrate SAWs in different ways at different frequencies, working the liquid sample in different ways.
