摘　　要：物理实验中经常需要采集大量的实时数据，通过对数据的压缩可以节省宝贵的存储资源。本文针对数据的‘连续’性特点，提出一种差值及符号位编码的压缩方法，对一些数据可以实现一定的压缩效率。Physical experiments often involve large amount of data acquisition. In some circumstances, data compression is highly required to save the precious storage media. Since the physical data are often continuous, a new kind of data compression method is introduced to take advantage of the continuity.This method includes a differential calculation and sign bit coding and presents about 40% savings.

关 键 词：数据压缩 差值 符号位编码
