利用gzip.dll解压http请求返回的内容。内附gzip.dll。参考网上资料自己写的VB6工程源码。自己编译EXE的时候注意把gzip.dll释放到exe所在目录。(Use gzip.dll to decompress the content returned by HTTP request. Gzip.dll is attached. Refer to the VB6 project source code written by myself.)

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)

霍夫曼编码的C++实现,输入一组字符串，输出每个字符的编码及整个字符串的霍夫曼编码。(realization of Huffman coding using VC++)

实现Huffman算法，对数据进行最优编码压缩。(huffman code)

一种改进的方案，它针对硬故障集的特点利用指示频率连续长度码(FDR码)进行二次编码压缩。该方法充分利用测试集中无关位较多而测试模式之间变化位较少的特征，应用贪心算法对预先计算的测试集进行了重新排序，尽可能的使相邻的向量间具有最少的不同位，排列成一个最佳的差分向量序列，然后应用FDR码对差分向量序列进行编码,最后对压缩结果重新分块，按照一次压缩的流程进行二次压缩。在解压时，使用片上解压电路解压，能高效地还原出原测试集。最后通过对Soc部分标准电路硬故障集的测试结果显示，本方案具有较好的压缩率。(a new improved method was proposed in the paper,the method using Frequency-Directed Run-length(FDR codes)coding for the twice aimed at hard-fault. It fully takes advantage of the characters that there are many don’t-care bits in the test set but a few different bits between the test patterns, Then it applies the greed calculate way to sort the precomputed test sets and make the close together vector have the least different sites possibly. It uses the FDR codes to coding the vectors,then blocks the results and uses the FDR codes to compress for the second time. Decompression used of on-chip circuit extract unpack,it will be deoxidize the original test efficient.using the hard-fault to compress and the experimental results prove that the improved coding method of this paper has the better compression ratios has been proved at last. )

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)

不可压缩稳态滑块润滑，一定长度的变间隙油膜厚度解析(Incompressible variable gap steady slide lubrication film thickness resolve certain length)

说明：  对流数据的压缩，主要针对二进制的数据代码进行各种长度宽度的压缩。(convection data compression, mainly with regard to the binary code of various length width of the compression.)
