说明: 变分模态分解的整体框架是变分问题,使得每个模态的估计带宽之和最小,其中假设每个“模态”是具有不同中心频率的有限带宽,为解决这一变分问题,采用了交替方向乘子法,不断更新各模态及其中心频率,逐步将各模态解调到相应的基频带,最终各个模态即相应的中心频率被一同提取出来(The whole framework of variational mode decomposition is variational problem, which makes the sum of the estimated bandwidth of each mode minimum. It is assumed that each "mode" is a finite bandwidth with different center frequencies. To solve this variational problem, the alternating direction multiplier method is used to update each mode and its center frequency continuously, demodulate each mode to the corresponding fundamental frequency band step by step, and finally each mode is called the first mode The corresponding center frequencies are extracted together)

有限元计算程序(matlab)
它将求解域看成是由许多称为有限元的小的互连子域组成,对每一单元假定一个合适的(较简单的)近似解,然后推导求解这个域总的满足条件(如结构的平衡条件),从而得到问题的解。(It regards the solution domain as consisting of many small interconnected subdomains called finite element elements, assumes a suitable (relatively simple) approximate solution for each element, and then deduces that the solution of this domain satisfies the conditions (such as the structural equilibrium condition), so as to obtain the solution of the problem.)

C# 创建泛型字典的例子
C# 创建泛型字典,为泛型字典添加3个元素,按键值对泛型字典进行排序操作。
Dictionary users = new Dictionary();//创建泛型字典
users.Add(3, new UserInfo(1, "滕*敏", "01"));//为泛型字典添加3个元素
users.Add(2, new UserInfo(2, "滕*娜", "02"));
users.Add(1, new UserInfo(3, "X家兴", "03"));
//按键值对泛型字典进行排序操作
var query = from item in users
where item.Value.UserName.CompareTo("滕*") > 0//用户名大于"滕立"
orderby item.Key
select item;
label1.Text = "显示查询结果:
";
foreach (var item in query)//显示查询结果
