In connection with the slowly stepping of the code phrases when using L-Z algorithm to compress the documents with many repetition characters,we propose a new algorithm in this article.That is increasing a run-length bit to the L-Z algorithm.We expound the principle of the new algorithm,compare the manometric efficiency with that of L-Z when processing the documents with many repeated chararcters and obtain that the new algorithm has a higher compression efficiency than that of L-Z.When processing with common text,we suggest to divide the text in order to get a higher compression efficiency compared with L-Z.
