摘　　要：根据色度学原理,利用宝石颜色自动化测量系统,量化翡翠颜色的参数指标,包括其1931CIE色度坐标、主波长、彩度与明度以及相应的反射率曲线和1931CIE色度图。依据主波长值,可区分翡翠颜色的主色调;由彩度值的大小可判断翡翠绿色的浓艳程度,同时划定高翠的量化数值概念;对比相关参数的变化,可以判断黑罩对翡翠颜色的负面影响。实验结果表明,利用光纤光谱仪、适当的照明方式及光谱采集方法,应用色度学原理,可以客观、定量地描述翡翠的颜色,可作为评价翡翠颜色的适用技术。According to the principle of colorimetry, the colour parameter indexes of jadeite jade are quantitized by the gemstone colour auto-measurement system, including 1931CIE chromaticity coordinates, dominant wavelength, chroma, lighness, reflection curves and 1931CIE chromaticity diagram. Through the dominant wavelength, the main tone of the colour of jadeite jade can be distinguished. According to the chromaticity value, the thick degree of green tone can be judged, and the quantitative concept of the fancy green jadeite jade can be defined. By the contrast of the correlation parameters, the negative influence of the black tone to the colour of jadeite jade can be also judged. The results of the experiment illustrate that the gemstone colour auto-measurement system is feasible to the colour evaluation and quantitative description of jadeite jade objectively with the fiber-optic spectrometer, the appropriate method of lighting and spectrum collection and the application of colorimetry principle.
