Author, starts from the one - way wave equation of wavefield extrapolation, research the relationship and transform condition of wavefield extrapolation operators, and propose the steady variational reference slowness rytov approximation general screen wavefield extrapolation operator ( vrselrf ) which can adapt severe lateral velocity variations, in frequency - wavenumber domain, and the improved wavefield extrapolation scheme, also give the method to improve the computation efficiency. the achievement establishes the theoretic basis of the whole research
首先，從波場延拓的單程波方程出發，系統地研究了頻率波數域的波場延拓運算元之間的相互關系和轉換條件並在此基礎上提出了能適應劇烈橫向變速的頻率波數域穩定的變參考慢度rytov近似廣義屏波場延拓運算元（ vrselrf ）和部分波場延拓改進方案及提高運算效率的措施，為整個研究打下理論基礎。 -
The extrapolation was used in this method for improving efficiency and accuracy, and the quasi shannon interval wavelet collocation method was constructed based on the concept of interpolation wavelet transform. this method can handle the problems of complex boundary conditions and improve computation accuracy greatly
在此基礎上，根據區間插值小波的概念，構造了擬shannon區間小波配置法，數值算例表明該方法不但可以消除邊界效應，而且可大幅度提高計算精度。
