基于光电信?息的产品地?理标识鉴别?研究 专 业：2008测?-1 学 号： 学生姓名：赖 指导教师：郝勇 摘要 地理标志作?为一类新型?的知识产权?，已得到越来?越多的重视?。地理标识又?称原产地标?记，是标记于商?品或服务之?上，标明与该商?品质量、商誉，有密切联系?的来源地的?国家、地区或地方?的名称。地理标识产?品是具有一?定特色和品?质的商品，该产品特色?得到了消费?者的认可，故具有品牌?效应。在市场经济?中，就可能有他?人假冒该地?理标志产品?以求高额利?益。目前，传统地理标?识检测主要?以化学方法?为主，往往需要多?种化学仪器?和试剂，样品需要预?处理、操作繁琐和?耗时费力。近红外光谱?检测技术因?其快速和无?损等优点，在产品地理?标识检测中?得到越来越?广泛的应用?。近红外光谱?技术是指利?用近红外光?谱包含的丰?富的物质信?息实现有机?物或部分无?机物的定性?和定量分析?的一种分析?方法。 本文以不同?品牌的食醋?为研究对象?，结合近红外?光谱分析技?术，探讨聚类分?析（包括系统聚?类分析和K?-均值（K-means?）聚类分析）、主成分分析?（包括二维主?成分分析和?三维主成分?分析），Fishe?r线性分类?法，K最邻近法?，偏最小二乘?判别分析法?（PLSDA?）等模式识别?方法在食醋?品牌鉴别中?的应用。并比较了这?些方法的优?缺点，实现食醋品?牌的最优鉴?别。 关键词：近红外光谱?；地理标识；食醋品牌；聚类分析；主成分分析?；Fishe?r线性分类?；K最邻近法?；PLSDA? Produ?cts ident?ifica?tion of geogr?aphic?al indic?ation?s based? on the photo?elect?ric infor?matio?n Abstr?act Geogr?aphic?al indic?ation?s has been paid more and more atten?tion to as a new type of intel?lectu?al prope?rty right?s. Geogr?aphic?al indic?ation?s, also known? as the origi?n of marke?r, is marke?d with the goods? or servi?ces, and marke?d with the produ?ct quali?ty and good will, or marke?d with the sourc?e of natio?nal, regio?nal or local? name. Geogr?aphic?al indic?ation?s for produ?cts with certa?in chara?cteri?stics? and quali?ty of goods?, has been recog?nized? by consu?mers, with its produ?ct featu?res and brand?. In a marke?t econo?my, it is possi?ble to be fake the geogr?aphic?al indic?ation? produ?cts in order? to achie?ve high inter?ests. At prese?nt, the tradi?tiona?l geogr?aphic?al indic?ation?s detec?ted by chemi?cal metho?ds often? requi?res a varie?ty of chemi?cal appar?atus and reage?nts, and the sampl?e shoul?d be pretr?eated? with tedio?us and time-consu?ming. Near infra?red spect?rosco?py detec?tion techn?ique (NIRS) with its rapid? and nonde?struc?tive and other? advan?tages?, is more and more widel?y used in the detec?tion of geogr?aphic?al indic?ation?s of produ?cts. Near infra?red spect?rosco?py techn?ique is a metho?d of analy?sis using?
