| 摘 要： | 采用电子鼻对三种不同年份的番茄种子进行分析.结果表明:利用电子鼻可以很好的区分不同年份的番茄种子；利用主成分分析方法(PCA)基本上可以辨别出不同掺杂比例的种子,但是当掺杂比例为37.5%和50%时,较难利用电子鼻进行辨别区分；利用线性判别分析方法(LDA)可以很好的辨别出不同掺杂比例的番茄种子,并且每个混合种类的区域...

| Abstract: | An investigation was made to evaluate the capacity of an electronic nose to classify the tomato seeds with different storage time.The tomato seeds with different storage time were blended each other at different proportion.The data were processed by Principal Component Analysis(PCA)and Linear Discrimination Analysis(LDA).The result shows that the electronic nose can distinguish the different storage time tomato seeds without blending easily.The tomato seeds blended each other at different proportion are dis... |
