摘　　要：汉语文本压缩至今很少受到重视，然而，作为许多计算机应用系统的支撑技术，其重要性毋庸置疑。本文结合汉语文本的特征对现行文本压缩技术进行评述，指出汉语文本理论上可能获得的平均压缩比率（〉３．９）及现行压缩算法所能达到的水平（１．６左右）。此外，讨论了汉语文本压缩的研究方向以及几种典型的应用。Chinese text compression has got little attention,but its importance as one supporting technique for many computer applications is beyond any doubt. This paper has investigated current theories and methods of text compression in accordance with the characteristics of Chinese text. It shows that Chinese text compression can even reach an average compression ratio as high as 3.9 theoretically,while it merely stays at around 1.6 with current compression algorithms. Besides,some research directions of Chinese text compression as well as its major applications are also discussed..
