蒸发温度对电子鼻白酒评价的影响研究
摘要
采用气体传感器阵列对7种市售白酒进行了动态测量
并研究蒸发温度对白酒识别分类的影响。白酒样本分别在20
40
60
80℃蒸发后进行测量
在每个蒸发温度下结合主元分析(PCA)法
分析了传感器阵列信号与白酒的香型和酒精度特征之间的关系
以及所有白酒样本按蒸发温度划分的结果。结果表明:按香型和酒精度划分
60℃的分类结果最佳
对白酒样本进行适当蒸发
有助于提高电子鼻测量的聚类性能。
Abstract
Seven commercial liquors are dynamically measured by a gas sensor array.The influence of evaporation temperature on liquors identification and classification is studied.Liquor samples are respectively measured after being evaporated at 20
40
60
80℃.The relationships between the respondings of the sensor array and the aromatic types and percentages of alcohol of the liquors are analyzed by using principal component analysis(PCA) method at each evaporation temperature.The results of liquors classification are also analyzed at different evaporation temperatures.The best results of classification are obtained at 60℃.Appropriate evaporation can help to improve the clustering performance of measurement by electronic nose.
