说明：  潜水器上浮模拟，对上浮中的速度、能耗和时间进行分析(Floating simulation of submersible)

读取串口数据并画实时曲线的VC源码，我试过了，修改一些就可以用了-Read the serial data and pictures of the VC-source real-time curve, I tried to amend some can use

说明：  读取wav音频数据的函数，可用于绘制WAV波形图，进行语音识别，哼唱别等。最基础的函数，但网上真正开源的C或C++版代码少，特别是将语音数据规范化的函数部分。代码是C++,但很容易改为C版，1:动态内存部分和释放内存的代码是C++的。2：求浮点型绝对值的fabsf函数是C++库里的。都是初学就有能力改成C版的。(Function of reading wav audio data(c plus version))

说明：  实现信号的时间反转，将信号进行还原，获取时间反转后的信号(Realize the time reversal of the signal and restore the signal)

说明：  意法半导体400W大功率BOOST PFC电路。双管并联。(The board implements a 400 W, wide-range mains input, PFC pre-conditioner suitable for ATX PSU, Flat screen displays, etc. To make possible the use of a low-cost device like the L6562A at this power level, usually prohibitive for TM PFC, the chip operates with Fixed-Off-Time control. This allows continuous conduction mode operation, normally achievable with more expensive control chips and more complex control architectures.)

播放器的c语言程序，通过读取音长基数的值，确定发音的频率，然后按频率值发出歌曲的音调。-Player of the c language program, read through the duration of the base value, to determine the frequency of pronunciation, then issued by the frequency of the pitch songs.

说明：  使用2020，IGRF-13球谐系数，计算点位磁正常场。igrf.m，输入点位三维坐标(Use 2020, igrf-13 spherical harmonic coefficient to calculate point magnetic normal field,IGRF. M, input three-dimensional coordinates of point position)

说明：  用plot3函数绘制三维螺旋线....Drawing three-dimensional helix with plot 3 function(Drawing three-dimensional helix with plot 3 function)

说明：  MATLAB蚁群算法机器人行驶路线紧急避碰(Ant colony algorithm)

用数据库和jsp编写添加，查询的营业网点项目(Use database and JSP to compile business outlet items that add and query)
