摘　　要：针对核物理研究中多道谱数据的特点 ,提出了一种可用于无损压缩的变换关系 ,成功地实现了其中的一种算法 ,获得了 0 .5至 0 .2 5的压缩比 。A new method of lossfree compression based on the feature of the data of nuclear spectrum is provided in this paper, from which a practicable algorithm is successfully derived. A compression rate varying from 0.50 to 0.25 is obtained and the distribution of the processed data becomes even more suitable to be reprocessed by another compression such as Huffman Code to improve the compression rate.
