UG调用的动态链接数据库-2503 called dynamic link database

操作系统用的进一步理解各种算法的性能，并且进一步理解各种页面替换算法的优缺点。 -operating system with the further understanding of algorithms, and to further understanding of pages replacement algorithm are discussed.

It is about finidng the real and reactive power given some harmonics in the system.

C# 改变屏幕分辨率，功能仿windows 的屏幕分辨率设置，改变滑块改变分辨率大校本例可学习一下滑块的用法。源代码如下： 　　long RetVal = 0; 　　DEVMODE dm = new DEVMODE(); 　　dm.dmSize = (short)Marshal.SizeOf(typeof(DEVMODE)); 　　dm.dmPelsWidth = dWidth;//宽 　　dm.dmPelsHeight = dHeight;//高 　　dm.dmDisplayFrequency = 85;//刷新率 　　dm.dmFields = DEVMODE.DM_PELSWIDTH | DEVMODE.DM_PELSHEIGHT | DEVMODE.DM_DISPLAYFREQUENCY | DEVMODE.DM_BITSPERPEL; 　　RetVal = ChangeDisplaySettings(ref dm, 0);

求解二维热传导方程，文档中有过程和matlab程序。 本文利用有限差分法来求二维热传导方程的数值解，通过Matlab编程求解并作图，进而与解析 解做出的图进行比较，画出误差图。(Solving the two-dimensional heat conduction equation, there are procedures and MATLAB programs in the document. In this paper, the finite difference method is used to find the numerical solution of the two-dimensional heat conduction equation, and is solved and plotted by Matlab programming. The diagram made by the solution is compared, and the error map is drawn.)

说明：  socket 通讯 ABPLC(socket communication using AB PLC)

实现并查集这一功能，利用了C++语言进行，效率更高(realize bingchaji,I use c plus plus,which is better to use)

说明：  基于结构光相移法的三维重建程序，matlab编码，由于要的可以下载一下(Based on the structured light phase-shift method of three-dimensional reconstruction program, matlab coding, because you can download it)

说明：  窗体自适应，统计原始窗体的位置和大小；缩放后Resize通过计算主窗体的大小，计算出长宽伸缩比例，然后再计算出来内部控件的起始点和长宽，过程通过递归完成，简单易行！(The window adapts itself and counts the position and size of the original window; after scaling, resize calculates the length and width scaling ratio by calculating the size of the main window, and then calculates the starting point and length and width of the internal control. The process is completed by recursion, which is simple and easy!)
