AVO 及其作用 AVO(Amplitude Versus Offset,振幅随偏移距的变化)技术用于研究地震反射振幅随炮点与接收器之间的距离即炮检距(或入射角)的变化特征。
English Description：
AVO and its effect AVO (amplitude versus offset) technology is used to study the variation characteristics of seismic reflection amplitude with the distance between shot point and receiver, that is, shot offset (or incident angle)
