中文摘要：

目的：研究主成分分析法及聚类分析法在微晶纤维素分类中的应用。方法：测定了来源于5个不同厂家的12种PH101和PH102型微晶纤维素的粉体学等物理性质,采用主成分分析法及聚类分析法对微晶纤维素的分类进行研究。结果：主成分分析和聚类分析的分析结果一致,主成分分析揭示了PH101和PH102型微晶纤维素分类的依据。结论：主成分分析法和聚类分析法可以用于微晶纤维素的分类研究,其结果与传统生产应用中微晶纤维素分类一致。

英文摘要：

Objective：To study the application in classification of MCC by principal component analysis（PCA）and cluster analysis method.Method：Determined powder property and other physical properties of 12 kinds of PH101 and PH102 MCC types which obtained from 5 different manufacturers,then PCA and cluster analysis method were used to investigate the classification of MCC.Result：The same result was obtained from PCA and cluster analysis method,it revealed that the basis on classification of PH101 and PH102 MCC types by PCA.Conclusion： PCA and cluster analysis method can be applied to study the classification of MCC with the result was the same as classification of MCC in traditional production application.
