Results: Two-dimensionspectrum of Radix Polygoni Multiflori from different sources have their obvious ir characters.
结果：不同产地何首乌的二维相关红外光谱谱图特征明显不同。

Then, inputting the two-dimensionspectrum entropy into the SVM classification, the result shows that SVM has fine compute efficiency and classified ability.
In this paper, we summarize the application of NMR at high molecular materials in recent years, from liquid NMR-solid NMR twodimension NMR correlation spectrum.
