摘　　要：随着海量数据进入我们的生活,数据压缩成为计算机科学领域中十分活跃的论题,游程编码与哈夫曼编码是两种典型的无损压缩编码的方法,通过对两种编码压缩思想的分析,并对游程编码算法进行改进,将两者联合起来进行数据压缩,以期达到更大压缩比的目的。With great deal of data enter into our life, data compression is a very active theme in the current computer science field. Run - length coding and Huffman coding as two typical of non - losing compressing coding algorithm has many important application to the current compression field. Following the analysis of the principle of two compression coding this disquisition gives a dission and research to a combined compression coding algo- rithm, in order to attain more proportion of compression.
