摘要
为了便于快速地传送大量的实验数据，减少通信线路的占用时间；以及方便实验人员处理实验数据，我们采用小波极大模方法对ＨＬ１Ｍ装置上的等离子体诊断数据进行了压缩。结果证明压缩１２倍后的重建结果能与五点三次光滑后压缩两倍的数据比美，能保持原数据形态与特征。
For speeding up remote data transmission and saving storage, a local maxima of a wavelet transform is used to compress the experimental data of HL 1M tokamak. It is shown that the compression algorithm reduces the data size to an average factor of 12, and the reconstructed data is better than the data which compressed by using a method of five point smoothing and sampling in an alternate data in keeping main features of the original data.
