二维地震波场快照放映机制的VC^(++)实现

THE REALIZATION OF PROJECTING SNAPSHOT FOR 2-D SEISMIC WAVEFIELD WITH VC^(++)

地震波的传播是一个与时间相关的动态过程,可以通过求解波动方程,分析得到的波场快照来研究地震波传播过程。波场快照的连续放映使得离散数据与时间的相关性得以恢复,有助于全面认识地震波传播过程。这里给出了二维波场快照放映的程序实现过程,提出数据加载并成像到内存设备环境的方法,以及处理定时器消息实现放映的方法,并对快照数据的存储格式和其它数据加载成像方法进行了讨论。基于上述方法,利用VC++的MFC工具编制了一个程序实例,实例的应用效果验证了该方法的有效性。

The propagation of seismic wave in a specific medium is a dynamic process with respect to time.We can study this process under the help of snapshots obtained from the arithmetical solution of wave equations.Projection of snapshots can resume the relationship between discrete data and time,so that it will be a great help to the extensive study of the propagation of seismic wave.A process of programming realization of the 2-D snapshot projection and methods of data loading,memory device imaging,and timer message processing are presented in this paper.After these presentations,it also discusses a possible format of snapshot data and another data loading and imaging method.The theory in this paper proves to be feasible after testing of an example program developed by MFC of Visual C^++.
