摘　　要：网络数据在传输过程中要先经过RAR编码进行压缩,节省传输时间。RAR格式的数据压缩编码在信息存储、信息管理、通信及保密方面得到广泛应用。其编码生成的压缩文件,存储格式复杂并且独特,包含有不同的数据块。根据RAR编码的显著特点,对RAR文件二进制码流块所包含的比特位做了定位分析,为研究其译码以及纠错译码算法奠定了基础。Network data must be first compressed through RAR coding in the process of transmission, and thus the transmission time could be reduced. RAR compressed format files are widely used in processing, running, communication, information hiding and so on. The compressed format files are intricate and particular, and contains different data blocks. The article, based upon the distinct characters of RAR coding, makes location analysis on the bit contained in the binary code stream block, thus laying a foundation for the decoding and error-correct decoding algorithm in RAR compressed format files.
