电子鼻传感器阵列优化及其在醋的分类中的应用

利用6个TGS系列气敏传感器阵列对醋进行了检测。按照Wilks统计量最小的原则对传感器阵列进行了优化，得到了由4个传感器组成的用于检测醋的种类的最佳传感器阵列。对阵列优化前后的数据，用PCA、LDA进行对比研究，结果表明，优化后的阵列可以更好地对醋鉴别分类。因此，所给出的优化方法是有效的。

Optimization of electronic nose and its application in the classification of vinegar

Vinegars are measured by a gas sensor array composed of six TGS gas sensors.An optimal sensor array consisting of four sensors is got,which is optimized based on the principle of Wilks Statistic Minimization and used to detect the type of vinegars.PCA and LDA were applied to analyze the data of primary and optimized sensor array.The results indicate that optimized sensor array could be more adaptable to recognize vinegars.Thereby the given optimization method is effective.
