First  establish an appropriate extrapolation model based on the existing data series  and then fit correlation functions other than existing data by derivative least squares method  finally perform spectrum analysis using extrapolated correlation functions. Numerical simulations and the experimental results show that good results are achieved no matter correlation functions change slow or rapid  and the extrapolation error is not more than 2.3%. 2012 Springer-Verlag Berlin Heidelberg.   EFFICIENT PARALLEL HYBRID COMPUTATIONS FOR THREE-DIMENSIONAL WAVE EQUATION PRESTACK DEPTH IMAGING 期刊论文  OAI收割 INTERNATIONAL JOURNAL OF NUMERICAL ANALYSIS AND MODELING, 2010, 卷号: 7, 期号: 2, 页码: 373-391 作者:  Zhang, Wensheng;  Wong, Yau-Shu   |  收藏  |  浏览/下载：19/0  |  提交时间：2018/07/30 prestack depth imaging  prestack migration  wavefield extrapolation  wave equation  hybrid method  parallel compuation  MPI   Optimized Chebyshev Fourier migration: A wide-angle dual-domain method for media with strong velocity contrasts 期刊论文  OAI收割 GEOPHYSICS, 2010, 卷号: 75, 期号: 2, 页码: S23-S34 Zhang; JH (Zhang; Jin-Hai); Wang WM(王卫民); Wang; SQ (Wang; Shu-Qin); Yao; ZX (Yao; Zhen-Xing) 收藏  |  浏览/下载：20/0  |  提交时间：2011/04/28 FINITE-DIFFERENCE MIGRATION  WAVE-EQUATION MIGRATION  COMPLEX-SCREEN METHOD  PLUS INTERPOLATION  ELASTIC-WAVE  3-D  EXTRAPOLATION  PROPAGATION   Optimized Chebyshev Fourier migration: A wide-angle dual-domain method for media with strong velocity contrasts 期刊论文  OAI收割 GEOPHYSICS, 2010, 卷号: 75, 期号: 2, 页码: S23-S34 Zhang; JH (Zhang; Jin-Hai); Wang WM(王卫民); Wang; SQ (Wang; Shu-Qin); Yao; ZX (Yao; Zhen-Xing) 收藏  |  浏览/下载：10/0  |  提交时间：2011/05/03 FINITE-DIFFERENCE MIGRATION  WAVE-EQUATION MIGRATION  COMPLEX-SCREEN METHOD  PLUS INTERPOLATION  ELASTIC-WAVE  3-D  EXTRAPOLATION  PROPAGATION   Asymptotic error expansion and Richardson extrapolation of eigenvalue approximations for second order elliptic problems by the mixed finite element method 期刊论文  OAI收割 APPLIED NUMERICAL MATHEMATICS, 2009, 卷号: 59, 期号: 8, 页码: 1884-1893 作者:  Lin, Qun;  Xie, Hehu   |  收藏  |  浏览/下载：15/0  |  提交时间：2018/07/30 Second order elliptic eigenvalue problem  Mixed finite element method  Asymptotic error expansion  Richardson extrapolation  Raviart-Thomas element   Approximation and eigenvalue extrapolation of Stokes eigenvalue problem by nonconforming finite element methods 期刊论文  OAI收割 APPLICATIONS OF MATHEMATICS, 2009, 卷号: 54, 期号: 1, 页码: 1-15 作者:  Jia, Shanghui;  Xie, Hehu;  Yin, Xiaobo;  Gao, Shaoqin   |  收藏  |  浏览/下载：13/0  |  提交时间：2018/07/30 Stokes eigenvalue problem  stream function-vorticity-pressure method  asymptotic expansion  extrapolation  a posteriori error estimates  nonconforming finite element methods   A note on Richardson extrapolation of Galerkin methods for eigenvalue problems of Fredholm integral equations 期刊论文  OAI收割 JOURNAL OF COMPUTATIONAL MATHEMATICS, 2008, 卷号: 26, 期号: 4, 页码: 598-612 作者:  Huang, Qiumei;  Yang, Yidu   |  收藏  |  浏览/下载：16/0  |  提交时间：2018/07/30 Fredholm integral equations  semi-simple eigenvalues  asymptotic expansion  Galerkin method  Richardson extrapolation  Sloan iteration   Weak approximations and extrapolations of stochastic differential equations with jumps 期刊论文  OAI收割 SIAM JOURNAL ON NUMERICAL ANALYSIS, 2000, 卷号: 37, 期号: 6, 页码: 1747-1767 作者:  Liu, XQ;  Li, CW   |  收藏  |  浏览/下载：19/0  |  提交时间：2018/07/30 jump diffusion  Ito-Taylor expansion  weak convergence  extrapolation method
