| 摘 要： | 该文把GB2312-80的汉字转换为从0至6767的短整型数，这些短整型数据有一个共同的存储特点：它们的2字节中的高3位（称为冗余位）皆为0。删除冗余位而重组其余位即可形成压缩文本。这种压缩方法显然是简单、快捷、容量实现和对GB2312-80汉字是普遍适用的。

| Abstract: | In this paper, the chinese characters of GB2312-80 are transformed into short integral numbers distributing from 0 to 6767. Every one of these short integral numbers is stored in a cell of two bytes, and the 3 higher bits, named redundance bits, in the cell are always zero. Omitting the redundance bits and reorganizing the others, the compression text of chinese characters is formed. The compression method is simple, quick, easy to implement and universal for all texts of chinese characters of GB2312-80. |
