使用FFT分析信号幅度谱和相位谱

二维雷诺方程的matlab有限差分算法。(Matlab finite difference algorithm for two-dimensional Reynolds equation.)

说明：  C语言及MATLAB语言随机介质建模代码，生成随机介质模型，C语言版本需要安装fftw，附件里面有压缩包及安装方法。(C language and MATLAB language Random Media modeling code, generate random media model, C language version needs to install fftw, the attachment contains compression package and installation method.)

二维FDTD程序，以方柱为例仿真其散射的波形(Two-dimensional FDTD procedures for square cylinder as an example simulation of the scattering wave)

Example source code to update database at runtime, in delphi source

说明：  在分隔器窗格中切换视图 (switch view in separators pane)

极值理论POT模型阈值选取，matlab代码。(POT model; extreme value theory)

绘制双层各向异性介质AVO曲线，可以更改介质类型(Drawing the AVO curve of anisotropic medium,the type of medium can be changed.)

说明：  轴承故障诊断，自己编写的基础EMD分解程序，实测很好用。(Bearing fault diagnosis, self-compiled basic EMD decomposition program, the actual measurement is very useful.)

不仅用于潮位调和分析和预报，还能对潮流进行准调和分析，包含两种功能，一次性解决潮汐问题，是目前为数不多的程序包。(Not only for tidal level harmonic analysis and forecasting, but also the tidal current analysis, including two functions, one-time solution to the tidal problem, is currently a precious packages.)

说明：  采用泰森多边形法根据区域内雨量站经纬度计算各站点权重，以此权重与各站点雨量相乘后累加得到面平均雨量(The Tyson polygon method is used to calculate the weight of each station according to the latitude and longitude of the rainfall station in the area, and the weight is multiplied by the rainfall of each station to accumulate to obtain the surface average rainfall)
