谐波分析，加窗fft插值算法，幅值校正；多次谐波；峰值搜寻(Harmonic analysis；fft)

计算地波传输衰减的程序,可以设置高度，大气条件等(Ground wave transmission attenuation calculation program, you can set the height, atmospheric conditions, etc.)

Hypercomplex mathematical morphology

3DFFT,对三维数据进行傅立叶变换，效果较好.可以用于三维的地震资料处理(3DFFT, three-dimensional Fourier transform of the data, the better can be used for three-dimensional seismic data processing)

说明：  一维黎曼问题，一维问题，即激波管问题，是一个典型的一维可压缩无黏气体动力学问题，并有 解析解。对它采用二阶精度两步差分格式进行数值求解。(Riemann problem, One dimensional problem, the shock tube problem, is a typical one-dimensional compressible non viscous gas dynamic problem with analytic solutions. It is solved numerically by two order two step difference scheme.)

weno5求解sod激波管问题，是初学计算流编程时做作业的题目，供参考(sod shock problem solve by weno5 for reference)

数值分析课程必备的算法：列主元高斯消去法算法。有需要的同学下载(Numerical analysis courses required algorithms: PCA out Gaussian elimination algorithm. Those students in need to download)

瑞雷波勘探的书籍，比较清晰的PDF文档，里面含有瑞雷波正演代码，一最小二乘反演代码，对学习瑞雷波非常有帮助。(Rayleigh wave exploration books, clear PDF document, which contains the Rayleigh wave forward code, a least squares inversion code, very helpful for learning Rayleigh wave.)

有限元编程做网格划分的，对于从事有限元分析的比较有用(Programming the finite element mesh to do the, for finite element analysis of the more useful)
