南航C++书后第三章习题，用的是C++语言编写，但是是vc6.0的老版编译器编写！(Chapter 3 exercises after Nanhang C++ book are written in C++ language, but it is written by the old compiler of vc6.0.)

给定一组物品，每种物品都有自己的重量和价格，在限定的总重量内，我们如何选择，才能使得物品的总价格最高(Given a set of items, each item has its own weight and price, within a limited total weight, what we choose to make the total price of the highest items)

读写USB串口，USB驱动，C#编写，demo(read and write USB serialport ,USB driver, DeMoPGM)

两款HTML5 jQuery滑动展开式图片导航菜单，大家都说是手风琴菜单，因为看上去像展开的菜单像琴键一样，可以折叠展开，基于HTML5和CSS3实现，配合jquery，功能更加强大，动画效果更加流畅自然，而且风格漂亮。

说明：  压缩点云数据，利用正方体中点的重心代替其中所有点。。。。。。。。。。(Compressed point cloud data)

说明：  设计半径为1mm的平面波经凸面曲率半径为25mm，中心厚度3mm的平凸透镜。用matlab仿真平面波在透镜几何焦平面上的聚焦光斑强度分布，计算光斑半径。并与理论光斑半径值进行对比，得出误差大小。（方法：采用波动理论，利用基尔霍夫—菲涅尔衍射积分公式。）(Design a plano-convex lens with a plane wave radius of 1 mm and a convex curvature radius of 25 mm and a center thickness of 3 mm. Matlab simulates the intensity distribution of the focused spot on the geometric focal plane of the lens with a plane wave, and calculates the spot radius. The error is compared with the theoretical beam spot radius.)

一些基本的数字图像处理算法，还比较全面、实用-some basic digital image processing algorithms, but also more comprehensive, practical
