Abstract
探讨了将小波变换处理方法应用到不同生长年限人参的二维红外相关光谱数据预处理中。结果表明：经过小波变换处理后，可以有效提高二维红外相关光谱同步图的分辨率，增强谱图中的信号峰，提高谱图中重叠峰的分离度，还可提供新的信息，从而在很大程度上增强了二维红外相关光谱对复杂体系的分析鉴别能力。借助此方法，可以鉴别人参的生长年限。
Wavelet transform was applied to the pretreatment of dynamic spectra data of two-dimensional infrared correlation spectroscopy. The results showed that with the pretreatment, the resolution of synchronous spectrum was noticeably improved. The peaks in the spectrum were toned up, and were separated from each other much more clearly than before. All these enhanced the performances of two-dimensional infrared correlation spectroscopy in analyzing and identifying complicated system. With this approach, ginseng of different ages can be identified.
