噪音衰减 meaning in English
sound attenuation
Examples
- Prestack noise attenuation application to high resolution seismic processing
叠前噪音衰减技术在高分辨率处理中的应用 - Because of the seismic data acquired from not the ideal condition but unexpected field , what we can do to increase the signal - noise ratio is to attenuate noise in processing
1 、迭代法噪音衰减：采用多道统计，单道压制的原则，分阶段以循序渐进的方式对噪音进行衰减。 - Signal can not be created but be enhanced by attenuating many kinds of noise from field by processing , so , is ridiculous to say , " do n ' t worry , we can get anything we want by processing "
值得说明的是，迭代法噪音衰减、迭代法振幅补偿和串联反褶积这三个处理过程不是彼此孤立的，而是相互联系的，这三个处理过程也是有机的组合，起到互补效果。 - This paper presented a new approach for stacking velocity analysis , and discussed the principles , procedure , applicability , and applications of suppression of prestack random noises and outliers based on the new stacking velocity analysis method
提出了一种新的叠加速度分析方法，并详细描述了基于这种新的叠加速度分析进行叠前随机噪音衰减和野值压制的原理、实现步骤、应用条件以及应用效果。 - 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
