摘要
本文以活性炭吸附丝采集“永芳F真珠膏”的挥发性组份，用GC－9A气相色谱仪进行测定。对24个真品进行R型聚类分析和因子分析，提取了14个特征指标，并以Q型聚类方式建立了鉴别“永芳F真珠膏”真伪的数学模型，用3个假冒产品和2个真品对模型进行验证，结果令人满意。
The volatile compounds of 'YongFang F pearl cream' were absorbed by coated wire, and analyzed by GC-9A chromatography. The results of 24 true products were studied by using R-type cluster and factor analysis, and 14 features were extracted. The mathemati cal pattern of identifying true of false of 'YongFang' was established by Q-type cluster. It is satisfactory that the pattern was verified by testing 3 false and 2 true products.
