摘要
目的讨论理气类中药之间的相互关系，为该类中药的复方组方研究提供新的思路。方法将中药药性进行量化处理，然后应用模糊聚类方法进行分析。结果当选取阈值λ≤0．45时，所有23种药物聚为一类。当λ为0．5～0．6时，所有药物分为二类。当λ=0．65时，所有药物分为三类。当λ=0．70时，所有药物共分为九类。结论运用模糊聚类分析方法将有类似功效的药物归类，有利于讨论理气类中药之间的相互关系，对于深入研究该类中药的性质和临床用药都是有意义的。
Objective To discuss the relationship in herbal medicines which are used for Qi-regulating so as to provide a new method for the studies on the rules of these herbs to form the prescription in Chinese herb medi- cines. Methods The drug properties were transformed into corresponding numerical value through quantitative disposal and the analysis is carried out by fuzzy clustering method. Results All these twenty-three kinds of Chi- nese herbs clustered into a class when threshold was equal to 0.45 or less than 0.45. It was clustered into two class when threshold was equal to 0.5-0.6. It was clustered into three class when threshold was equal to 0.65 and clustered into nine class when threshold was equal to 0.70. Conclusion These Chinese herbs which have similar effect can be classified by fuzzy clustering and it was beneficial to discuss the relationship in various herb medicines for Qi-regulating. All this may be of some positive significance for the further studies of both the nature and the clinical application of these herb medicines.
