情人节表白攻略，大家来试试吧,很有意思的(Valentine' s Day confession Raiders, everyone to try it, very interesting)

说明：  灰色系统中，基于分数阶累加的DGM模型的调用函数,函数的名字比较奇怪，因为是在组合程序中使用的。使用时将该调用函数的名字更改即可。 为使得程序执行，相应的累加累减函数同时给出。(The function of DGM model which is imprtant model in the grey system.)

Reversible Data Hiding

心音与肺音的提取与分离，噪声的基础性的去除。(The extraction and separation of heart and lung sounds, the basic removal of noise.)

说明：  Second use of visual studio

VHDL代码 键盘扫描，数码管静态移位显示，类似于计算器显示数据-VHDL code

一个完全用C语言实现的贪吃蛇游戏，在TC环境下运行！对于初学C的同志，写个小游戏无疑是打基础的好方法，同时也提高自己对编程的兴趣！(A Snake game entirely in C language to run in the TC environment! Beginner C comrades to write a small game is undoubtedly a good way to lay the foundation, but also improve their own interest in programming!)

电力系统潮流计算体现在数学就上是多元非线性方程组的求解问题，求解的方法有很多种。牛顿—拉夫逊法是数学上解非线性方程式的有效方法，收敛性好、迭代次数少。将牛顿—拉夫逊法用于潮流计算是以导纳矩阵为基础的，由于利用了导纳矩阵的对称性、稀疏性及节点编号顺序优化等技巧，使牛顿—拉夫逊法解题规模和计算速度进一步提高，此算法至今仍是潮流计算中广泛采用的优秀算法。(Power flow calculation in power system is a problem of solving multivariate non-linear equations in mathematics. There are many methods to solve it. Newton-Raphson method is an effective method for solving nonlinear equations in mathematics. It has good convergence and fewer iterations. The application of Newton-Raphson method to power flow calculation is based on admittance matrix. Because of the use of symmetry, sparsity and optimization of node number sequence of admittance matrix, the scale and speed of Newton-Raphson method are further improved. So far, this algorithm is still an excellent one widely used in power flow calculation.)
