multiple attenuation meaning in Chinese

多次反射衰减

According to these accomplishments , several techniques are expounded emphatically in this paper , including 3d refraction statics , coherent noise suppression by prestack wave field separating ( prestack fx noise attenuation ) , 3d prestack multiple domain random noise attenuation , multiples attenuation , nmo of unsymmetrical hyperbola , dynamic replacement of wave equation , surface - inconsistent residual static , super bin stacking , poststack depth migration and prestack depth migration . all the techniques have been applied in seismic processing of 2d , 3d and wide - line profiling and obtained good results
