用C++的模板类实现的霍夫曼树及其编码过程，可视地展示霍夫曼树的结构。(Huffman tree and its encoding process to achieve C++ template class, visual display of the structure of the Huffman tree.)

263yasuoyuv.rar是把yuv-411格式文件压缩为*.263可直看(263yasuoyuv.rar is yuv-411 format for the*. 263 files can be read straight)

基于类函数形函数的参数化建模方法，适用于气动设计和优化(Class/Shpae Transform method)

工程之间的转换 主要针对 05 和08 希望对大家有帮助(Projects aimed at the conversion between 05 and 08 We want to help)

文件的解压缩。添加文件unzip.h、unzip.cpp、zip.h、zip.cpp，调用对应函数进行压缩和解压。压缩格式为zip；压缩之后的文件可以用winrar等程序打开。(File decompression. Add file unzip.h, unzip.cpp, zip.h, zip.cpp, call the corresponding function for compression and decompression. Compression format is zip the file after compression can be opened by winrar.)

基于霍夫曼算法的压缩与解压程序。其中压缩与解压的exe是分开的。(Using Hoffman algorithm to compress and decompress)

采用LBM+LES方法编制 了计算程序.首先计算了湍流平板附面层解,用来校对程序的正确性,结果表明计算值和理论值符合得很好.然后计算了亚音可压缩的湍流后台阶流以及超音湍流的 后台阶流.(LBM+LES simulation of flow)

视音频课程作业，对视频抽帧，对单张图片进行yuv420采样、DCT变化、量化以及反量化、IDCT变化(Jpeg Encoding & Decoding)

输入两个正整数m和n，求其最大公约数和最小公倍数(Enter two positive integers m and n, can seek the common denominator and least common multiple)

说明：  用单片机来直接驱动步进电机很精确走小步子.(Using single-chip to directly drive stepper motor is very accurate take small steps.)
