燃料电池的simulink模型，该燃料电池的原型为Ballard Mark-700,75kw(fuel cell simulink model )

这里给出另一组对谱线校正的方法，其中包括了9种方法。(Here are the other group on the spectrum correction method, including nine kinds of methods.)

Silicon channel semivector : Applies the semivector modesolver to compute the TE mode of a sub-micron silicon waveguide. Comparison with the full-vector solution demonstrates some of the inaccuracy of the semivector approximation.

对信号进行离散傅立叶变换，完成对信号的频谱分析(fft analysis)

介绍了关于memory的相关函数，对于大多数程序员有很大帮助，希望大家多多使用(the information about memory)

用matlab画出smith圆图的M文件，已经验证，结果正确，部分行需要去掉回车即可运行。(Draw smith chart matlab M-file has been verified, the result is correct, part of the line needs to be removed then press enter to run.)

搭建的双馈风力发电机变流器控制模型，我自己做项目的时候用过，效果很好，大家可以随便用。 (Converter control model of doubly-fed wind power generator, I was working as a project, the effect is very good, you can literally use. )

说明：  用7次多项式进行机器人关节空间的轨迹规划(The trajectory planning of robot joint space is carried out by using 7 degree polynomial)

说明：  遗传算法 多目标优化算法，SPEA2 主要流程：1：首先初始化一个archive的集合P1，以及一个常用的population的集合P。设置P1的大小是N1，P的大小是N。初始的时候P1是空的，而P是已经初始化好的种群个体。 2：对P1进行评价，选出来里面的pareto front为1（下面用PF1来代替了）的个体，copy到P1中，如果PF1的数量大于N1的话，这个接下来再说，目前假定PF1的数量小于N1。(Genetic algorithm, multi-objective optimization algorithm, SPEA2 Main process: 1: first, initialize a set P1 of archive and a set P of popular. Set P1 to N1 and P to n. At the beginning, P1 is empty, and P is the initialized population. 2: Evaluate P1, select the individual whose Pareto front is 1 (Pf1 is used to replace it below), copy to P1, if the number of Pf1 is greater than N1, then let's talk about it. At present, it is assumed that the number of Pf1 is less than N1.)

c++语言中利用输入输出流来实现各种复杂图形的绘制(c++ language, using input and output streams to achieve the rendering of complex graphics)
