Text is a kind of very common resource in digital library, and lossless techniques play an important role in compressing text. starting from the shannon ' s entropy theory, we analyze the lossless compression algorithms, and implement arithmetic coding algorithm in c. in the experiments, we compare four different lossless compression algorithms by their performances such as compression rate, compression rate tendency with the length of data, stability, and complexity, using 35 groups data series with 4 different length
本文從信息論中shannon熵定理出發，對無損壓縮技術進行系統地分析，用c語言實現了其中的算術編碼演算法，並用它對35組、四種不同長度數據序列進行了壓縮，給出了實驗結果，然後從壓縮比、壓縮比隨字元串長度的變換趨勢、演算法穩定性和演算法復雜性等四個方面對其與其它三種壓縮演算法lzw 、 lz77 、 rle進行了分析與比較。
