处理各种文档的小程序，很实用。而且里面包含许多小技巧，是初学者的首选...

解决很多地下水数值模拟问题，只需要修改相关参数就能运用(Groundwater numerical simulation to solve many problems, only a need to amend the relevant parameters will be able to use)

机器人小车代码，自己可以修改。做自己的智能车，上面提供了PWM定义。采用PID算法小车循迹

c++实现的sift，可以分步观看实现效果(c++ implementation of the sift, you can watch step by step to achieve results)

采用STM32F103开发的一款简易四旋翼无人机飞控及遥控代码，适合想做无人机的同学研究借鉴。(A simple four rotor UAV flight control and remote control code developed by STM32F103 is suitable for students who want to do UAV research and use for reference.)

说明：  STM32F103 串口透传，两个串口相互透传程序，串口接收中断再发送(STM32F103, two UART Pass-through Program)

opengl 实现太阳系的模拟 地球自转和公转(opengl sun earth moon)

B curve left key point, right end vevr good(Curve B left key point, right end vevr good)

网络爬虫程序，C++实现！程序完全开源！(Network reptiles procedures, C++ Realize! Procedure is totally open source!)

读取文本中的数据，然后应用Qpainter进行绘图。(Read the data in the text, and then apply the Qpainter to plot.)

通过DS18B20读取温度（范围-55C~125C，精确到小数点后一位），通过4位数码管显示出来。 当温度为正且百位为零时，不显示，当温度为负时百位显负号。当温度百位和十位都为0时0都不显示。(Read through the DS18B20 temperature (range-55C ~ 125C, accurate to one decimal), through four digital tube display. When the temperature is zero and 100, do not show, when the temperature is significantly negative at minus 100. When the temperature is 100 and 10 are not displayed 0:00.)
