摘    要:和田玉通常是以颜色为依据进行分类的,但当和田玉颜色相近且渐变,即颜色只存在深浅、色调细微变化时,对其进行准确分类就很难了。而类别的错位划分会影响其价值及科学研究等。为解决这个难题,结合市场需求,运用感官分析方法,结合数理统计等原理确定出白玉青玉系列样品中白玉、青白玉下限标准样品。由此也表明在和田玉国家标准样品的研制中,感官分析技术数据可靠,方法可行。

关 键 词:感官分析  区间选取  成对比较检验  和田玉  颜色分类

Abstract:Nephrite is generally classified according to colours. While the colours of nephrite are similar and gradient, only deep or light, it is very difficult to be classified exactly. However, dislocated classification of nephrite will affect the value and scientific research. In order to solve this problem, according to the demand of the jade market, with the use of sensory analysis methods and the application of the principles of mathematical statistics, this paper puts forward the lowest thresholds of the standard samples to determine the colours of white nephrite and greenish-white nephrite, which also shows that the technical data from the sen- sory analysis are reliable and the methods are feasible in the development of national standard sample.
Keywords:sensory analysis interval selection paired comparison test nephrite colour classification
