jQuery为图片添加文字提示内容，鼠标放在图片上，会出现文字提示，效果相当不错，仅供学习参考。

说明：  这也是一本线性代数的教材，其讲法十分现代，抛弃了行列式为主的传统讲法，直接紧扣线性代数中最核心的算子理论。(This is also a textbook of linear algebra. Its teaching method is very modern, abandoning the traditional teaching method based on the determinant, and directly following the core operator theory in linear algebra.)

GTRACK Track mouse position and show coordinates in figure title. Once GTRACK is active the mouse position is constantly tracked and printed on the current figure title. A left-click will print the coordinates in the command line and store them. Clicking the mouse right button deactivates GTRACK.

说明：  此为对粒子群算法的改进，采用高斯混沌变异，效果优于原算法(This is an improvement on the particle swarm algorithm. It uses Gaussian chaos mutation, which is better than the original algorithm)

VB纯API调用Windows“保存”对话框，不知道有没有用，送给学习VB的参考吧。

OpenCv QML C++ 的混合编程，实现图处理等功能(QML C++ mixed programming using qquick to develop front-end interface open library and logic layer using C++ development)

永磁同步电机无位置传感器高频注入仿真模型，可以运行(Permanent magnet synchronous motor without position sensor high frequency injection simulation model, can run)

ASP编写的一个公司网站的源程序，学者可以使用学习-ASP prepared a source of the company"s Web site, academics can use to learn

说明：  利用有限差分法求解雷诺方程，效果非常好，需要的同学可以自己下载！(Using the finite difference method to solve the Reynolds equation, the effect is very good. Students who need it can download it by themselves!)
