摘　　要：讨论了对二维核磁共振数据进行噪声剔除与数据压缩的一般原理与方法,介绍在Sun图形工作站上的实现情况,并给出实验结果与分析。In this paper, we have introduced some general principles and methods for noise elimination and data compression of 2D NMR spectral data, including phase -sensitive mode, power mode and absolute mode spectra. The idea was originated from the necessity of alleviating some problems of NMR spectrometer, such as user -time tramming and limit storage device. Some technicalities were notified combined with a brief description of the implementation of those methods on Sun SPARC workstation . To show the applicability and feasibility of the methods, we present an experiment instance which gain a 10 : 1 compression ratio with respect to the original spectral data.
