pscad做的整流器控制模型，运行效果良好(Rectifier control model of PSCAD, good results)

常见的各类数值和字符算法，包括微积分、插值、矩阵、微分方程、方程组求解和字符串操作等，Fortran77版本，可直接用于各位自己的代码开发中(Most common algorithms, including numerical and char recipes, Fortran 77 version, can be used in your own program develpment directly)

光滑粒子（SPH）模拟couette流动，代码是根据刘桂荣老师《光滑粒子流体动力学-一种无网格方法》书后的代码改编，较实用，请需要的下载(Smoothed Particle (SPH) simulation couette flow, the code is based on Liu Guirong teacher " smoothed particle hydrodynamics- a non-grid method" Code adaptation of the book, more practical, please download required)

葛德彪第二版FDTD后面彩图三对应的程序，源程序有部分错误，已更正，并已验证完全正确，内附建立散射体模型的源程序(The second FDTD version of the second edition of Ge Deyi corresponds to the program in color image three. The source program has some errors, has been corrected, and has been verified to be completely correct. The source program for creating a scatterer model is included.)

该损伤模型通过 商用有限元软件ABAQUS /Explicit 的用户子程序VUMAT 实现，并使用该模型对碳纤维增强环氧树脂 复合材料层合板在横向低速冲击作用下的损伤和变形行为进行预测分析． 数值仿真的结果与试验结 果进行了比较，吻合良好，验证了该模型的有效性．(Through coding user subroutine VUMAT of finite element software ABAQUS /explicit， and applied the model to an example，carbon fiber reinforced epoxy composite laminates under low velocity impact，the prediction for damage and deformation were good agreement with the experimental results．)

MPI与Fortran的并行程序实例，ＳＵ最新源码，实用 (MPI parallel program with Fortran instance, SU the latest source code, and practical )

这是一个希尔伯特变换的程序包，里面共有5个程序，可用于普通的希尔伯特变换(This is a Hilbert transform of the package, a total of five procedures which can be used in ordinary Hilbert Transform)

一个用Fortran写的LBM数值计算的例子，例子包括了离子扩散和电化学反应的耦合作用。压缩包里有源代码，三个EXCEL是用于流动区域划分的。(An example of LBM written in Fortran numerical examples include the coupling of ion diffusion and electrochemical reactions. Source code compression package, three EXCEL is a flow zoning.)

可将实测河道断面转化为梯形断面，用于平原河网水动力学计算。(The measured channel section can be transformed into a trapezoidal section)
