摘　　要：介绍了可视嗅觉敏感阵列的制作方法,并用制成的敏感阵列对二甲胺,三甲胺,二乙胺,三乙胺和二异丙胺共五种具有分支状分子结构的有机胺进行了识别。实验结果表明,可视嗅觉敏感阵列对这五种结构相似,性质相近的有机胺的图像响应模式具有高度的特异性,目视即可区分。对响应模式的主成分分析显示,可视嗅觉阵列甚至能区分甲胺,乙胺和丙胺之间的类属差异。A method of developing Smell-seeing sensitive arrays is presented. The sensitive arrays are then used to recognize and discriminate five branched amines： dimethylamine, trimethylamine, diethylamine, triethylamine and diisopropylamine. The results show that the sensitive array＇s image response patterns upon the five amines with similar structure and property are highly special to each other, which can be discriminate even by eyesight. A further PCA analysis shows that the Smell-seeing sensitive array can discriminate even the class differences among methylamine, ethylamine and propylamine.
