说明：  上大学时候的一个习作，是模仿国外一个截图软件做的。它不但可以抓图，而且还可以选择抓图的形状，比如圆形、方形、三角形等。还有其它的一些辅助功能有很多(When one exercises in college, is an imitation of a screenshot of foreign software to do. It can not only drawings, but can also choose the shape of drawings, such as round, square, triangle and so on. There are some other auxiliary functions, many)

简单的图形学SRGP教学包运用实现。 A．实现一个下拉菜单软件包，其高层设计见2.2.6节、2.3.1节、2.3.3节中的代码段。软件包通过从输入文件读入字符串来初始化菜单条和菜单体。程序可以通过关闭菜单条使标题消失，也可以激活一个菜单（以各菜单标题在菜单条上的水平位置作为参数）来使菜单出现。 (Simple graphics SRGP realize the use of teaching packages. A. The realization of a drop-down menu package, and its high-level design, see section 2.2.6, section 2.3.1, section 2.3.3 of the code segment. Package from the input file is read into the string to initialize the menu and menu body. Procedures can be closed so that the title menu disappear, but also can activate a menu (in the menu heading in the menu bar on the horizontal position as a parameter) to make the menu appear.)

利用VC6.0实现的图形绘制工具，功能非常全面，非常强大，适合专业级的人员使用。(VC6.0 achieved using a graphical drawing tools, which is very comprehensive, very powerful, suitable for professional-level personnel.)

这是瑞利信道中有关多普勒频移的多径信道和单径信道的相关matlab仿真程序,(This is relevant in Rayleigh channel doppler frequency shift of channel multipath channel and a single diameter related matlab simulation program,)

自己在PSCAD中搭建的PLL，用的是分立元件搭建的，有助于自己学习以及编程实现，已经与自带的PLL进行对比，验证了正确性(PSCAD built himself in the PLL, using discrete components built to help you learn and programming has been compared with the built-in PLL, verify the correctness)

这是计算机图形学中的一个实验，使用VC++编写，功能是实现用菜单和鼠标交互式画圆。(This is the computer graphics an experiment, the use of VC preparation, function is using interactive menus and mouse Circle.)

用于C/C++/Visual C 二二维等值线的绘制，程序源码 (Drawn for two two-dimensional contour of the C/C++/Visual C program source)

一种参数化方法，可以用于对曲线进行参数化，在设计中可以用于减少设计变量。(Used to parameterize a curve, has similar function to the NURBS)

Qt编写的小程序，主要是编写类似visio的一部分功能(Small program written in Qt，Small program written in Qt)
