非饱和均匀沙一维数学计算模型

求一维序列x(n)的离散Fourier谱分析，s(0:m)离散功率谱，c(0:m)振幅谱，cta(0:m)位相谱，其中m=[n/2.]。(Discrete Fourier spectrum of one-dimensional series)

一维 问题，即激波管问题，是一个典型的一维可压缩无黏气体动力学问题，并有 解析解。对它采用二阶精度 两步差分格式进行数值求解。(Use MacCormack difference scheme for solving a two-dimensional shock tube problem)

自己建立的永磁直驱风力发电系统，采用dq解耦控制，spwm调制，机侧控制最大功率跟踪，网侧控制直流电压和无功。(The permanent magnet direct drive wind power generation system has adopted DQ decoupling control, SPWM modulation, machine side control maximum power tracking, network side control DC voltage and reactive power.)

This source file contains example PitchCntrl(), UserHSSBr(), ! UserVSCont(), and UserYawCont() routines that are used to interface ! FAST with a master controller implemented as a dynamic-link-library ! (DLL) in the style of Garrad Hassan s Bladed wind turbine software ! package. All four routines call routine BladedDLLInterface(), which ! contains a call to the Bladed-style DLL that evaluates as DISCON(). ! Routine BladedDLLInterface() USEs a MODULE named ! BladedDLLParameters(), which stores values of PARAMETER constants ! used in the interface.

说明：  这本书是纳比吉安的电磁法的经典之作，现在市面已经很难找到，希望对想学电磁法的朋友，能有一定的帮助。(This book is the electromagnetic Nabi Ji law classic, and now the market has been hard to find, want to want to study electromagnetic method of friends, can have some help.)

说明：  Guide to FORTRAN 2008 Programming

Dr. Liu 在《光滑粒子流体动力学--一种无网格方法》一书中提供的光滑粒子流体动力学（SPH）源程序，采用Fortran语言编写，用于计算可压缩流体力学问题。(Dr. Liu in the " Smooth Particle Hydrodynamics- a meshless method," a book provided by the smooth particle hydrodynamics (SPH) source code, using Fortran language, used to calculate the fluid flow problem.)
