说明：  本文档包含了射频微波电路的一些设计技巧和注意事项。(This document contains a number of RF and microwave circuit design techniques and considerations.)

数字信号处理，输入一段加有噪声的信号，经过一段滤波程序后输出有用波形(Digital signal processing, input a signal with noise added, after a filtering procedure useful for waveform output)

声波模拟的去频散程序，能有效减少频散效应。。。。(Dispersion modeling to the sound process, can effectively reduce the frequency dispersion effect. . . .)

程序均用matlab编写 ch ex 的文件是信号与系统频谱密度函数或者时移特性的展示 Advanced_Mathematica_picture_zoom是利用二次线性内插值法对彩色图片进行任意倍数的放大 每个程序都含有详细的注释(Programs are written in matlab chex file is spectrum density of signal and system function or moving features of the display Advanced_Mathematica_picture_zoom using quadratic linear interpolation method in arbitrary multiple amplification was carried out on the color images Every program contains detailed annotations)

这是一本最经典的matlab工具书，中文的，通俗易懂，更适合初学者，而且该PDF比已有的要更加清晰工整。(This is the most classic matlab books, Chinese, user-friendly, more suitable for beginners, and the PDF than the more clear and neat. )

捷联惯导和合成孔径雷达组合导航程序，地理坐标系下的(SINS integrated navigation and synthetic aperture radar program, geographic coordinates of the)

海量工业数据处理使用，包括了稳态测试，剔除坏值，计算标准差和平均值等(Massive use of industrial data processing, including the steady-state test, remove bad values, calculate the standard deviation and mean, etc.)

说明：  小波去噪程序，在别人的程序上有一定的修改，对于任意声音文件a.wav进行小波去噪。(Wavelet denoising procedure, in others there are certain procedural changes, for any sound file a.wav wavelet denoising.)

MATLAB编写的汉字繁体简体转换程序，使用GUI(MATLAB Traditional Chinese Simplified preparation of the conversion process, the use of GUI)

说明：  自动生成三维的多孔介质，对多孔介质研究的学者有用(Automatic generation of three-dimensional porous media, porous media studies scholars Useful)
