ace源代码中附带的管理日志服务器实现的一个具体的小例子，希望能上传成功-ace in the source code attached to the log management server of a specific implementation of a small example of the hope of a successful upload

省时间省事情，非常简便计算速度较快，而且非常容易操作(Saving time and saving things is very simple and fast.)

聊天程序代码服务器端-Chat server code

说明：  这里一共提供了四种迭代法： + 雅可比迭代法 + 高斯赛德迭代法 + 超松弛迭代法（SOR） + 共轭迭代法(There are four iterative methods +Jacobi iterative method +Gauss side iterative method +Overrelaxation iterative method (SOR) +Conjugate iteration metho)

说明：  项目任务 在单链表类中增加一个功能erase(x, y), 删除表中所有值在 [x, y] 之间的结点。假设链表中结点数值类型是整形，要求编程返回删除相应结点后的链表长度和链表元素。 输入描述 第一行输入链表List的结点元素值，元素之间用空格间隔，且均为int类型； 第二行输入为x和y，分别表示需要删除结点元素的最小值和最大值。 输出描述 第一行输出删除相应结点后链表的长度； 第二行输出删除相应结点后链表的所有元素，元素之间用空格间隔。若无剩余元素，输出null。(Project tasks A function erase (x, y) is added to the class of single linked list to delete all nodes whose values are between [x, y]. Assuming that the numerical type of the node in the linked list is plastic, the program is required to return the length and elements of the linked list after deleting the corresponding nodes. Enter a description In the first line, enter the node element values of the linked list list, with spaces between the elements, and all of them are of type int; In the second line, input X and y to indicate the minimum and maximum values of node elements to be deleted. Output description The first line outputs the length of the linked list after deleting the corresponding node; The second line outputs all the elements of the linked list after deleting the corresponding nodes, with space between the elements. If there are no remaining elements, null is output.)

包括几种常用的无约束优化算法，比如最速下降法、BFGS算法、共轭梯度法等等(Including unconstrained optimization algorithms in common use)

DBCView对汽车电子行业的dbc文件进行解析，并进行拓扑图显示。DBCView清晰实现对dbc文件的解析，并以友好的界面展示CAN信号，Node，signal，MSG之间的关系的软件。对初入汽车电子行业的新人非常适合，能快速掌握dbc的结构。（dbc文件是vector公司定义的，用来描述单一CAN网络中各逻辑节点信息，依据该文件可以开发出来监视和分析CAN网络中所有逻辑节点的运行状态，也可以是有针对性的ECU通信应用软件。）(DBCView is a parser for dbc file and topology view to display. By the DBCView, user could quickly understand the links between node, message, signal and can bus. DBCView is support training tool for fresh person.(by the way, If you want to know dbc, you could get help from vector ))

eMule其实是一个开源项目，提供了优秀的p2p文件共享，这里提供了它的最新源代码。-quad is actually an open-source project, the quality of peer-to-peer file-sharing, where it provides the latest source code.

Theory of elasticity by Timoshenko and Goodier

An investigation of the effects of disorder on the modes of vibration of nearly periodic structures is presented. It is shown that, in structures with close eigenvalues, small structural irregularities result in both strong localization of the mode shapes and abrupt veering away, or mutual repulsion, of the loci of the eigenvalues when these are plotted against a parameter representing the disorder in the system
