【摘要】 本论文是在中国棉花检验体制改革中新旧两种体制发生根本性变革的前提下,对棉花色泽检验所发生的变革的相关研究。其研究数据采用了新疆各主要产棉区棉花的反射率、黄色深度值及棉检员评定的品级值,并使用SPSS13.0、Origin7.0软件进行数据统计分析和绘图处理;对新疆21级棉、3级棉进行了色特征聚类分析;同时研究了新疆棉花品级与色特征级的辨证关系。研究结果表明,同级棉花色特征可以按产地进行聚类,聚类分析结果与我区传统的棉区划分相一致——分为南北疆两大棉区,特别是21级的聚类分析结果与传统棉区的划分一致性较好;棉花品级与色特征级从宏观上分析具有一定的相关关系,但同一色特征级的棉花在品级上不一定相同,而同一品级的棉花一般都包含有不同的色特征级,同一色特征值的棉花品级也不一定相同;同时发现新疆棉花总体色泽较好。这样的研究有助于进一步了解我区棉花色特征的分布特点,及品级与色特征级之间的相互联系与实际应用,有助于推动新疆棉区更快的向仪器化检验过渡。更多还原

【Abstract】 This article is the research about reform in cotton color characteristic when the system of cotton examination is changing .The dater in this article is from cotton reflectance degree, cotton yellowness, cotton grade in the main producing area of Xinjiang and is analyzed by SPSS13.0, Origin 7.0. The Hierarchical Cluster Analysis and The Dialectic Relationship of Cotton Grade and Cotton Color Grade in Xinjiang are studied. It illustrates that the same grade cotton can be divided according to source area, especially analysis of 21grade cotton. At the same time, the cotton grade has some relation with color grade on the point of macroscopic, but they are not in accordance with each other. The cotton color and luster in the whole is better in Xinjiang. The research like this is beneficial to the understanding of cotton color characteristic in my area. It can avoid influence on two different systems so as not to fall in misunderstanding and fast the step into examination using instrument.更多还原
