zerooffset seismogram

用法例句

Shuey, the paper obtained more accurate zero-offset reflectivity by fitting reflectivity changed with incident angles, which improved the signal-to-noise ratio of seismic data,while did not fundamentally change the relationship of reflected amplitudes changing with offsets in original CMP gathers of seismic data that can further inverse the accurate section of AVO attributes.
