4) reverberation
[英][rɪ,vɜ:bə'reɪʃn] [美][rɪ'vɝbə'reʃən]
鸣震
1.
As the short travel time of ringing and reverberation in water body of extra-shallow sea,it results in mix with primary reflection easily and makes such processing measures as predictive de-convolution difficult to be effectively used.
由于极浅海地区水体中多次鸣震和混响的旅行时间较短,容易与一次反射波发生混叠,难以有效应用预测反褶积等处理手段。
2.
Hydrophone and vertically oriented geophone induce upward wave signal with identical polarity and downward wave signal with opposite polarity in OBC seismic prospecting, so the water column reverberation can be eliminated by scaling and summing pressure and velocity seismic data.
