C# 使用进程名禁止程序运行多次， 　　string moduleName = Process.GetCurrentProcess().MainModule.ModuleName; //获取当前活动进程的模块名称 　　string processName = System.IO.Path.GetFileNameWithoutExtension(moduleName);//返回指定路径字符串的文件名 　　Process[] processes = Process.GetProcessesByName(processName);//根据文件名创建进程资源数组 　　if (processes.Length > 1)//如果该数组长度大于1，说明多次运行 　　{ 　　 MessageBox.Show("本程序一次只能运行一个实例！", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);//弹出提示信息 　　 this.Close();//关闭当前窗体 　　}

基于buck电路的模型预测控制，通过电流跟踪(Model predictive control based on buck circuit, through current tracking)

雅克比迭代法就是众多迭代法中比较早且较简单的一种，其命名也是为纪念普鲁士著名数学家雅可比。雅克比迭代法的计算公式简单，每迭代一次只需计算一次矩阵和向量的乘法，且计算过程中原始矩阵A始终不变，比较容易并行计算。(The jacobian iteration method is one of the earlier and simpler iteration methods, which is also named in honor of the famous Prussian mathematician jacoby. The calculation formula of jacobian iterative method is simple. Every iteration only needs to calculate the matrix and vector multiplication once, and the original matrix A is always the same in the calculation process, which is easier to calculate in parallel.)

用最小方差间接自校正控制设计控制器，当被控对象的参数未知时，可首先利用递推增广最小二乘法在线实时估计对象参数，然后再设计最小方差控制律，即将对象参数估计器和控制器的设计分开进行，就形成了最小方差自校正控制间接算法。(The minimum variance indirect self-tuning control is used to design the controller. When the parameters of the controlled object are unknown, the recursive augmented least squares method can be used to estimate the parameters of the object in real time on line. Then the minimum variance control law is designed. The design of the object parameter estimator and the controller are separated, and the minimum variance self-tuning is formed. Positive control indirect algorithm.)

VB6.0在窗口中实现背景渐变，渐变可随窗口的大小变化自动填充，挺平滑的渐变，修改渐变可修改VB中的代码即可，本渐变不仅限于窗体背景，也可用于其它的窗口元素中，比如按钮和对话框中。
