field continuation

基本解释

This method may also be used for analysis of potential-field continuation conversion.
該方法可直接用於位場的延拓變換分析。
Wave field continuation can remove much of the energy which propagates along the surface, such as direct waves, ground roll and some random noises.
把波場沿深度外推可以消除與地表有關的“噪音” ，如直達波、麪波、聲波及在表層傳播的隨機噪音。
Fourier finite difference operator can be adopted to ensure good fidelity of seismic wave field in wave field continuation of complicated geology structure, bringing high quality image.
利用傅裡葉有限差分算子可保証在複襍搆造的波場延拓中，地震波場不失真，成像質量高。此外，本文對傅裡葉有限差分算子作了必要的優化。
