Comprehensively discuss the issues in application, adaptive condition and performance, propose a fast arithmetic of forward modeling and depth migration in common shot gathers with one - way acoustic wave equation based on vrselrf, and verify the arithmetic by numerical simulation. concisely discuss the cause of the creation of evanescence and the problem of lateral amplitude discontinuity result from it. fourthly, use the reflectivity model, computed to describe the fracture model, with the formula of computation reflectivity based on elastic - acoustic approximation, and the wavelet model computed by the method, wavelet creation with fourier transform, we proposed, in conjunction with vrselrf wavefield extrapolation operator
第三，將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 ）應用於疊前與疊后正演模擬、疊前與疊后深度偏移，對演算法應用中應注意的問題、適用范圍、性能等作了較為全面的論述；提出了基於vrselrf的單程聲波方程共炮記錄正演模擬和深度偏移快速演算法，並通過數值模擬試驗對演算法進行了驗證；簡要地討論了倏逝波的產生原因及其帶來的橫向振幅不連續性問題。 -
According the principle of the statistical energy analysis method, define subsystem the whole system into four subsystem : subsystem of rail ' s vertical vibration, subsystem of wheel ' s vertical vibration, subsystem of wheel ' s lateral vibration and subsystem of acoustic space. then define the power flow equation between the subsystems
首先根據統計能量分析方法中子系統劃分的原則，將整個結構系統劃分為：鋼軌的垂向振動子系統、車輪的徑向振動子系統、車輪的軸向振動子系統及聲空間子系統共四個子系統；並且建立了子系統間功率流平衡方程。
