Abstract: This thesis implements LZW compression algorithm by program, and improves it for Chinese compression. It proves to be efficient by the result of test. Compared with normal LZW12 compression algorithm, compression ratio is improved, the minimum compression ratio is about 34.7 percent for a long Chinese document, and the compression effect of a English text file is better than LZW12 algorithm. There is important value for application. ;;;
