摘要
用模糊聚类分析对溢油指示物甾烷进行了研究。为消除进样误差的影响 ,以标准化相对峰高为基本数据 ,推算出了油种及其甾烷的动态模糊聚类分析图。结果表明 ,油种的动态模糊聚类分析图可以显示油种间的疏近程度 ;甾烷的动态模糊聚类分析图可以表征溢油指示物各甾烷的贡献率 ,15个甾烷是模糊聚类分析的主要因子 。
Steranes as the indicators of spilled oils is studied with fuzzy clustering analysis.During the data processing,standardization methods of the relative peak height of steranes are adopted in order to eliminate the influence of the error of injection of samples of the oils.Based on data of the relative peak height of steranes,fuzzy dynamic clustering analysis charts of the types of oils and the steranes are drawn out.It is shown that relationship between the types of oils,ratios of contribution of the steranes as the indicators of spilled oils,fifteen kinds of steranes as superiority to indicators of spilled oils and main factors for the fuzzy clustering analysis,can be clearly expressed as the fuzzy dynamic clustering analysis charts.
