求勒让德递推公式

说明：  电压型逆变器，学习逆变器的基本模型，适合入门的者 仿真软件matlab(Voltage-type inverter, inverter to learn the basic model, suitable for those who get into simulation software matlab)

说明：  应用于粗糙表面线接触弹流润滑计算，自动生成随机分布的表面粗糙度程序。(It is applied to the calculation of linear contact elastohydrodynamic lubrication on rough surface to automatically generate randomly distributed surface roughness program.)

abaqus Umat 计算复合材料的损伤问题，可以学习一下(abaqus umat subroutine for damage of the composite material)

用于有限元软件Abaqus分析材料断裂的粘结区模型（CZM）子程序，由著名学者高彦飞编程，具有很高的参考价值。(ABAQUS allows the addition of a variety of user subroutines. We define a user element by UEL. Information of element and nodal displacements can be obtained from ABAQUS, and we update the stiffness matrix and the residual vector following the cohesive zone law. More coding details can be found in ABAQUS manual.)

这个是abaqus的子程序以及inp文件，可用用于材料生热的模拟。(it is the UMATHT for abaqus.)

说明：  利用PSCAD搭建的NLM调制的MMC模型(NLM Modulation Model Based on PSCAD)

说明：  大气辐射传输模型，求大气透过率和辐射亮度(Atmospheric Radiation Transport Model to Calculate Atmospheric Transmittance and Radiation Brightness)

Solver for linear ecuations system (SOR-successive over relaxation), very usefull!!.

燃气轮机的设计资料，书后附有燃气轮机整机和各个部件的设计程序，在每个程序中给出了设计实例。(Gas turbine design information, the book with the machine and the various components of the gas turbine design process, design examples are given in each program.)

用DEFORM3D的用户子程序功能,插入了包括动态再结晶过程的热粘塑性本构模型。使得两个版本的DEFORM3D都具备了微观组织演化的模拟和预测功能。(The thermal visco plastic constitutive model, which includes the dynamic recrystallization process, was inserted into the user subroutine of DEFORM3D. Makes the two versions of the DEFORM3D have a micro organizational evolution of the simulation and prediction function.)
