Results: Two-dimension spectrum 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-dimension spectrum entropy into the SVM classification, the result shows that SVM has fine compute efficiency and classified ability.
进一步将二维谱熵作为支持向量机（SVM）分类器的输入量，结果表明SVM具有良好的分类能力和计算效率，可以满足在线监测的要求。
