说明：  对不同的钢筋、混凝土材料本构进行定义，可集成于大型有限元软件ABAQUS，便于工程分析。(user-defined material subroutine for FEM software ABAQUS.)

风场EOF分析，适用于nc资料，对原始场、距平场、标准场，程序内有详细说明。(The wind field EOF analysis is applicable to the nc data, and the original field, the anomaly field, and the standard field are detailed in the program.)

说明：  Drucker-Prager准则是岩石力学中最为重要的强度理论之一，在岩土工程研究中，尤其是在岩土工程数值分析中应用极为广泛。(Drucker-Prager criterion is one of the most important strength theories in rock mechanics. It is widely used in geotechnical research, especially in numerical analysis of geotechnical engineering.)

说明：  UMAT子程序例子，mises屈服准则，弹塑性材料，sss(umat subroutine, von mises yield criteria)

常用的作物生长模型，从GitHub当的源码，利用Fortran编译成了可用的工程，可以直接运行，也可以按需修改代码(Commonly used crop growth model, GitHub when the source code, using Fortran compiled into the available projects, you can run directly, you can also press the need to modify the code)

这本书最初是为北京亚嵌教育研究中心的嵌入式Linux系统工程师就业班课程量身定做的教材之一。该课程是为期四个月的全日制职业培训，要求学员毕业时具备非常Solid的C编程能力，能熟练地使用Linux系统，同时对计算机体系结构与指令集、操作系统原理和设备驱动程序都有较深入的了解。(This book was originally embedded in education for the Beijing Asian Research Center Embedded Linux Systems Engineer job class curriculum materials tailored one. The course is a four-month full-time vocational training, ask participants to graduate with a very Solid C programming ability, be proficient in the use of Linux systems, and computer architecture and instruction set, operating system and device drivers are the principle a better understanding.)

物质点3维显示程序，含有材料模型，能求解碰撞(3D material point method)

基于Fortran的simple算法求解，源代码程序(Fortran-based simple algorithm to solve, source code program)

说明：  netDxf是一个用C＃编程的.net库，用于读写AutoCAD dxf文件。 它支持文本和二进制格式的AutoCad2000，AutoCad2004，AutoCad2007，AutoCad2010，AutoCad2013和AutoCad2018 dxf数据库版本。 该库易于使用，我试图使程序尽可能简单，例如，您不需要使用图层，样式或线型定义填充表格部分。 每次添加新项目时，DxfDocument都会处理这个问题。(netDxf is a .net library programmed in C# to read and write AutoCAD dxf files. It supports AutoCad2000, AutoCad2004, AutoCad2007, AutoCad2010, AutoCad2013, and AutoCad2018 dxf database versions, in both text and binary format. The library is easy to use and I tried to keep the procedures as straightforward as possible, for example you will not need to fill up the table section with layers, styles or line type definitions. The DxfDocument will take care of that every time a new item is added.)
