【摘要】：采用ATP附件采集了人工控制條件老化小麥樣品的太赫茲波譜數(shù)據(jù),并在PCA綜合得分基礎(chǔ)上對(duì)數(shù)據(jù)進(jìn)行分集,建立陳化小麥的快速無(wú)損鑒別PLS-DA模型,并對(duì)其進(jìn)行外部驗(yàn)證。結(jié)果顯示,針對(duì)吸收系數(shù)譜,所建模型的校正集實(shí)驗(yàn)組、對(duì)照組以及交互驗(yàn)證實(shí)驗(yàn)組、對(duì)照組正確率分別為84.2%,94.7%,84.2%和81.6%,外部驗(yàn)證集實(shí)驗(yàn)組、對(duì)照組正確率分別為73.7%和100.0%;針對(duì)折射率譜,所建模型的校正集實(shí)驗(yàn)組、對(duì)照組以及交互驗(yàn)證實(shí)驗(yàn)組、對(duì)照組正確率分別為84.2%,92%,76.3%和76.3%,外部驗(yàn)證集實(shí)驗(yàn)組、對(duì)照組正確率分別為84.2%和89.5%。研究表明,ATR-THz技術(shù)在陳化小麥無(wú)損鑒別方面具有一定的應(yīng)用潛力。
[Abstract]:The terahertz spectrum data of aged wheat samples under artificial control conditions were collected by ATP attachment, and the data were differentiated on the basis of PCA scores. The PLS-DA model of rapid nondestructive identification of aged wheat was established and verified externally. The results showed that the correct rates of the experimental group, the control group and the interactive verification group were 84.2% and 81.6%, respectively, according to the absorption coefficient spectrum. The accuracy rates of the control group were 73.7% and 100.0.The correct rates of the experimental group, the control group and the interactive verification group were 84.2% and 76.3%, respectively. The accuracy rates of the external validation group and the control group were 84.2% and 89.5 respectively. The results show that ATR-THz technique has some potential application in nondestructive identification of aged wheat.
