The optic fiber sensors of phase modulation type developed by the interference theory in traditional optics are high sensitive.
根据传统光学干涉原理研制出的相位调制型光纤传感器，其突出优点是灵敏度高。

The passive interference in receiving station of amplitude modulation (AM) broadcasting from UHVAC transmission lines is mainly caused by towers.
特高压输电线路对调幅广播台站的无源干扰主要是由垂直杆塔引起的。
