DESIGN AND DEVELOPMENT OF ADVANCED JET ENGINE

近场声全息数据和matlab程序，仿真效果好，达到成像的目的(Near - field acoustic holographic data and matlab program, the simulation effect is good, to achieve the purpose of imaging)

说明：  通过发送四轮的扭矩，通过pid控制对轮子输出速度进行调节(By sending the torque of four wheels, the output speed of the wheel is adjusted by pid control)

利用COMSOL计算二维光子晶体正方晶格能带(Using COMSOL to calculate the square lattice energy band of two-dimensional photonic crystals)

说明：  THe MCQS of Artificial Intelligence

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)

来自韩国的一款Flash产品图展示效果，鼠标只需放在菜单图片上，该项菜单内容即可展开显示，再次移走鼠标后，菜单恢复原状，看着还挺不错吧。

本文件包含代码和仿真图。 利用51单片机设计波形显示器完成以下功能： 1.能产生至少三种波形。 2.采用按键独立显示波形。 3.在LCD显示波形图案及其各项基本参数。 4.能同时显示两种波形。 5.波形参数可调。(We use the 51 microcontroller to design the waveform display to accomplish the following functions. 1. can produce at least three kinds of waveforms. 2. use the key to display the waveform independently. 3., display the waveform pattern and its basic parameters in LCD. 4. can display two kinds of waveforms at the same time. 5. waveform parameters are adjustable.)
