field continuation

基本解釋

This method may also be used for analysis of potential-field continuation conversion.
該方法可直接用于位場(chǎng)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(chǎng)沿深度外推可以消除與地表有關(guān)的“噪音” ，如直達(dá)波、面波、聲波及在表層傳播的隨機(jī)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.
利用傅里葉有限差分算子可保證在復(fù)雜構(gòu)造的波場(chǎng)延拓中，地震波場(chǎng)不失真，成像質(zhì)量高。此外，本文對(duì)傅里葉有限差分算子作了必要的優(yōu)化。
