| 摘 要： | 用主成分分析算法，对２７种云南菊科植物水提物中的７种微量元素Ｃｕ，Ｍｎ，Ｚｎ，Ｆｅ，Ｐｂ，Ｎｉ，Ｃｒ含量值进行了计算，获得了４个主成分及相应的主成分方程，详尽地解释４个主成分的理化意义。用主成分分析，能更清楚地反映植物微量元素含量本质性的特征、规律及内在联系，这对于进一步开发利用菊科植物具有重要意义。 |

| Abstract: | By using principal components analysis algorithm, the feature analysis for the values of seven traceelements, i.e. Cu, Mn, Zn, Fe, Pb, Ni, Cr, in water-soluble substance of Yunnan composite family is realized. Fourprincipal components and their equations are obtained. Physicochemical meaning of four principal components is explained in detail.This method clearly indicates the essential features, distribution law and internal relations among trace elements.This is of important significance for getting more economic results from the composite family. |
