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。 -
Differential equations for characteristic curves, velocity curves and slowness curves are given and the analytical expressions for wave fronts in orthotropic porous media are also obtained. the wave fronts in anisotropic fluid - saturated porous media are discussed in detail. in chapter 3, the plane wave propagation in orthotropic fluid - saturated porous media is researched according to biot ' s theory and the concept of dynamic permeability
