迭代算法用在曲面，曲线拟合，很好的一个算法(The iterative algorithm used in the surface, curve fitting, a good algorithm)

三角网格以及矩形网格剖分. 实现等参单元以及误差L H 范数收敛阶估计.(Triangular meshes and rectangular meshes are subdivided to achieve convergence order estimation of error L H norm.)

通过matlab计算allan variance，较为复杂，注释详细(Matlab Allan variance, more complex, detailed notes)

粉土的阻尼比拟合程序。拟合模型选择Davidenkov模型。(The silt damping match the proper procedure. The Fitting Model Davidenkov model.)

说明：  FFT，整型数据代替浮点型数据 本程序是搜集资料并加上自己的分析，整了很长时间才测试通过的FFT程序，运行时间和所占内存方面都比较满意。(FFT, integer data instead of floating point data This program is to collect data and add their own analysis, the FFT program passed the test for a long time, the running time and memory occupied are relatively satisfactory.)

说明：  郭照立D2G9(D2G9)

别人的程序（Fortran）是关于边界元法求解声学问题。(Someone else' s program (Fortran) is on the boundary element method to solve acoustic problems.)

自适应网格生成的文章，广泛的应用到有限元和无网格方法中(a nice paper of adaptive mesh generation)

本程序是采用FDTD算法结合PML吸收边界，对对称三层平板光波导的模式场仿真(This program uses FDTD algorithm and PML absorbing boundary to simulate the mode field of symmetrical three-layer planar optical waveguide.)
