对检层法测井中出现的浅层时间倒转问题实现模拟，更好的理解测井中的这一问题。(Logging on Logging Method shallow back in time to appear in the issue of analog, a better understanding of logging in this issue.)

intel 88E1111的数据手册，好不容易得到的，贴在这希望对大家有用(intel 88E1111 data sheet, finally get, posted in the hope that it would be useful)

以NACA0012 翼型为研究对象，采用拉格朗日法分析了重力对水滴撞击特性的影响，获得了过冷大水滴(SLD)撞击特性。(The influence of gravity on the droplet impingement property were analyzed with the Lagrangian method, and the supercooled large droplet (SLD) impingement property has been gotten based on the research of NACA0012 airfoil)

this is the simulink of wind power with pitch angle controler

说明：  计算一个方柱的散射的波形，并求其RCS。方柱的网格总数是N=500个，时间步为1200步。网格尺寸为lamda/18,时间间隔是ddx/2*c，c为光速。脉冲源位于中心。方柱边长为7*lamda。并与相同尺度的球的散射场进行对比(Calculate the scattered waveform of a square column and find its RCS. The total number of grids of the square column is N=500 and the time step is 1200 steps. The grid size is lamda/18, the time interval is ddx/2*c, and c is the speed of light. The pulse source is at the center. The side of the square column is 7*lamda. And compare the scattering field of the ball of the same scale)

本次作业是在matlab环境中实现的，主要运用了图像处理的基础知识对一张车牌图像进行预处理。如图像转换、图像形态学处理以及图像的边缘检测等来增强图像的对比度。在此基础上利用形态学方法以及投影法相结合来定位图片中的车牌，并将其从图片中剪切出来。最后，将提取出来的车牌字符分割成单个字符并组成新的图像。(This work is implemented in matlab environment, the main use of the basics of image processing on a plate image preprocessing. The image conversion, image processing, and morphological image edge detection or the like to enhance the contrast of the image. Morphology and projection Combination plates to locate the picture, and cut out the picture on the basis of use. Finally, the extracted license plate character segmentation into individual character and form a new image.)

基于顺势无功功率理论的无功电流和谐波电流检测，这里是两个，交流侧电流中的谐波电流是相同的。用来滤除电路中的无功功率。(Based on the theory of homeopathy reactive power reactive current and harmonic current detection (p, q op mode and ip, iq op mode))
