c语言实现的fft，形式为DLL，速度很快。可以直接调用(fft algorithm realized by C program is very fast,and it can be called directly. )

从windows程序种查找图标资源，提取图标。(Find the icon resource the windows program, extract the icon.)

一种应用VC爱好者对树形控件的理解的应用(An application for tree lovers VC understanding of application controls)

三维均匀介质的高阶交错网格弹性波方程数值模拟（未加PML吸收边界条件），模拟结果以切边形式显示(Numerical simulation of three-dimensional homogeneous medium of high-order staggered elastic wave equation (not PML absorbing boundary conditions), the simulation results are displayed in the form of trimming)

一个利用c#编写的广播发送代码，所在的编译环境是vs！(A use of c# Prepared to send broadcast code, where the compiler environment is vs!)

说明：  实现vc下不同进程之间的通讯：Copyrecv接收进程，Copysend发送进程(achieve vc different process of communication between : Copyrecv receiving process, this process Copysend)

directsound手册.pdf 参考(DirectSound manual. pdf reference)

接收系统消息不示例,可以提供初学者使用.(receive system message demon .using VC++)

说明：  这是一个很好的程序很好用,希望给各会员们提供方便.(This is a good procedure is useful, the members hope to provide convenience.)

多炮声波PML边界正演 时间二阶空间十阶 速度场为200*200 添加PML边界后为300*300.边界计算包括4个边及4个角点。初始震源位置位于（150，50处） 输入速度模型为3层，2000/2500/3000,放在model.bin中 输出数据为finite_difference_150_50_2.bin 主程序参考王恩江4239091.基于linux环境编译。(finite_difference，model based on linux envirenment,3 layer)
