悬臂梁MATLAB有限元算例注释
梁可视为平面应力状态，先按图示尺寸划分为均匀的三角形网格，共有8×10＝80个单元，5×ll＝55个节点，坐标轴以及单元与节点的编号如图。将均布载荷分配到各相应节点上，把有约束的节点5l、52、53、54、55视作固定铰链，建立如图所示的离散化计算模型。(The beam can be regarded as a plane stress state. Firstly, the beam is divided into uniform triangular meshes according to the graphic size. There are 8*10=80 elements, 5*ll=55 nodes. The coordinate axis and the numbering of elements and nodes are shown in the figure. The uniform load is distributed to the corresponding nodes, and the constrained nodes 5l, 52, 53, 54 and 55 are regarded as fixed hinges. The discrete calculation model shown in the figure is established.)

C++开发的推箱子游戏
1.类的划分
Cdraw类
绘画加载地图（包括围墙、人、箱子等等）
Cman类
是否完成（过关）
即时更新地图
2.设计思想
从文件map.txt里读取地图信息，然后通过Cdraw类加载地图，通过keydown事件调用Cman里的重载函数updatemap，
单参数updateMap(UINT nChar)是用于更改当前小人以及箱子的坐标，记录下来后传给updateMap(int x1, int y1, int x2, int y2, int x3, int y3)
从而改变地图。-C development Tuixiangzi a game. Class division Cdraw painting category loaded maps (including the wall, boxes, etc.) if the class completed Cman (clearance) updated maps 2. Design ideas from the paper map.txt Lane read map information, then pass Cdraw Class Loading maps, Calling the incident through keydown Cman Lane updatemap of overloading functions, updateMap single parameter (UINT nChar) is used to change the current villains and the coordinates of the boxes, After record pass updateMap (int x1, y1 int, int x2, int y2, x3 int, int y3), thus changing map.

1.1
创建一个计时测试程序，比较公式节点和本地LabVIEW数学函数的平均执行时间。此程序需要一个For循环或一个平序或叠序结构以及一个Case结构。要求For循环运行计时测验N次，然后使用Statistics Express VI对结果做平均。要求顺序结构在代码运行之前以及代码运行之后对Tick Count进行采样。要求Case结构判定用户是要执行公式节点还是要执行本地LabVIEW数学函数。对每个分支运行计时测验程序。哪种方法执行时间最快？哪种方法最容易编程？别人要看程序时，哪种方法更容易理解？(Create a timing test program to compare the average execution time of formula nodes and local LabVIEW mathematical functions. This program needs a For loop or a plain or overlapping structure and a Case structure. Require the For cycle to run the timing test N times, and then use Statistics Express VI to average the results. The sequential structure is required to sample Tick Count before and after the code runs. The case structure is required to determine whether the user wants to execute formula nodes or local LabVIEW mathematical functions. Run the timing test program for each branch.)
