Abstract：Mr.Yun Mei-hou has questioned about the argument of close relationship between resolution and S/N ratio expounded in my book "Road toward Precious Exploration" and considered that seismic resolution is only relative to dominant frequency and irrelative to S/N ratio of seismic waves.The author considered that it's necessary to clarify the issue.As concerns to same seismic data,the dominant frequency of reflections is not fixed in different processing stages,especially after the processing of deconvolution and high-pass filtering.The people can easily raise the amplitude spectrum at high-frequency end,which means the dominant frequency can be become higher.If there is not noise,the wavelet can be compressed into narrow pulse after pulse deconvolution,which makes the resolution reach as higher as possible,it's clear that the conclusion considering the seismic resolution is only relative to dominant frequency of seismic waves is not correct.Meanwhile,it should clarify that the seismic resolution is determined by useful frequency bandwidth of seismic data.
