migrating wave 中文意思是什麼
migrating wave
解釋
遷移波-
The synthetic source is the generalization of plane wave source, controlled illumination source, piecewise plane wave source and areal sources with phase encoding etc. by migrating the synthetic source record, the computational cost of the conventional areal shot record migration can be reduced by several times without significantly degrading the image quality
合成震源既包括了已有的平面波震源，也包括了控制照明震源，分段平面波震源和相位編碼震源。合成震源記錄疊前深度偏移方法是炮記錄偏移、平面波偏移、控制照明偏移和相位編碼面炮記錄偏移方法的推廣和統一形式。 -
Undulate acquisition surface is one of the main properties of the seismic datasets from western china. based on the synthetic source record migration method and wave stack principle, a method of migrating directly from the undulate surface is presented and tested
結合我國西部地震資料的特點，針對起伏地表情況下的地震數據成像問題，提出了與合成震源記錄偏移方法相應的成像方法以及基於共聚焦點技術的基準面向上校正方法。 -
In the paper, in order to reveal the characters of seismic migration image affected by velocity model and improve the precision of seismic migration and imaging, we present some analysis to the complex geology conditions, through modeling and migrating the theoretical model, deduce some features of seismic wave field imaging affected by velocity model, and give some advises to improve the imaging and some useful idea
為了揭示速度模型對地震波場偏移成像的影響特徵，提高偏移成像的精度，對一些復雜地質模型進行了波動方程正演和偏移，並從理論模型的數值模擬結果中，推導出了速度模型對地震波場偏移成像的一些影響特徵，提出了相應的改進建議和一些有益的結論和認識。
