摘　　要：介绍了小波变换的基本理论,并对其应用研究进行了评述。小波变换作为信号处理的强有力工具,其已在色谱信号的基线校正、平滑滤噪、谱图压缩、重叠色谱峰解析、中药指纹图特征提取等方面都有成功的应用。最后分析了小波变换在色谱应用研究中现存的问题,并对其未来的发展进行了探讨。Basic theories and applications of wavelet transform（WT） were described in this paper. As WT is a high performance signal processing technique, it has been applied to baseline correction , smoothing and de--noising, data compression, resolution of overlapping signal and the profile of medicinal herbs in chromatography. Finally, by analyzing some of the existent faultliness of the research on the application of wavelet transform, the future research and solutions are discussed.
