STM32的IAP升级程序，已经是可以用的，是用SD卡升级的程序，简单好用，有需要的朋友可以直接用(The STM32 IAP upgrade process, it is already possible to use, is to use the SD card upgrade program, easy to use, a friend in need can be directly used)

这是一款用MFC ADO编写的数据库软件，它可以实现对ACCESS数据库的打开，添加，修改，保存，排序得一系列的功能。它利用ListCtl进行显示(This is a MFC ADO with the preparation of the database software, it can be open to the ACCESS database, add, modify, save, sort a series of functions. It uses ListCtl display)

说明：  关于线性调频连续波的性能仿真应用，仿真代码及实现(Linear frequency modulation continuous wave)

三相平衡电网条件下的三相PWM整流电路，双闭环控制，SVPWM控制。(Three phase PWM rectifier circuit under three phase balanced grid condition, double closed loop control and SVPWM control.)

说明：  讲述浅海水声信道下的多途时延估计方法，供声学方向的学生学习参考(The multi-channel time delay estimation method in shallow underwater acoustic channel is described, which is a reference for students in acoustic direction)

可以根据风速风向数据绘制风场在不同方向上的分布情况(Distribution of wind field in different directions can be plotted based on wind speed and direction data.)
