fortran常用算法集-徐世良，配合书籍使用，很好用(Algorithm sets by xushiliang)

经过激波，气体的压强、密度、温度都会突然升高，流速则突然下降(After the shock, the gas pressure, density, temperature will rise suddenly, a sudden drop in flow velocity)

基于pscad利用PWM调制方法实现的逆变并网的仿真模型(Simulation Model of Inverter Grid Based on pscad Using PWM Modulation Method)

基于pscad的DFIG变速恒频双馈风力发电仿真模型，是2010年3月修改版，将直流母线电压降到800V，电机为0.9【MVA】。可以进行低电压穿越仿真。(Based pscad of DFIG VSCF doubly fed wind power generation simulation model is a modified version in March 2010, the DC bus voltage down to 800V, motor 0.9】 【MVA. Can be low voltage through the simulation.)

该程序通过编写fortran，得到abaqus之程序usdfld，并实例分析。(The program is by writing fortran, get abaqus procedures usdfld, and case analysis.)

说明：  it is a double circuit line simulation in pscad

说明：  等效粘弹性模型UMAT子程序，适合准备编程学习的朋友(Equivalent viscoelastic model -- UMAT subroutine)

适合于稀薄流动计算的气体动力学格式源码，该源码为xukun老是JCP论文中的算例一致(UGKS1D- shock structure calculation using Unified Gas-Kinetic Scheme)

说明：  Fortran的声辐射边界积分计算程序，使用常数网格单元(FORTRAN version of the acoustic radiation boundary integral calculation program, the grid is a constant element.)
