玛瑙省藤材表面视觉物理量的分布特征

The Distribution Characteristic of Rattan Surface Visual Physical Magnitude

采用色差仪和光泽度仪对玛瑙省藤（Calamus manan）材表面物理量进行测量,研究相应参数的色空间分布特征。结果表明：玛瑙省藤材的明度指数分布范围较窄,其表色系参数米制明度L＊为73.59-79.29、孟塞尔表色系参数明度V为6.25-6.78;色品指数和色调值参数分布范围较窄,其表色系参数米制红绿色品指数a＊为5.82-6.45、米制黄蓝色品指数b＊为19.86-21.83、孟塞尔表色系色调标号值H为7.77-8.27,主要分布在黄橙色调系内;饱和度范围较窄,孟塞尔表色系饱和度C为3.28-3.65,表色系参数饱和度C＊为20.69-22.77。垂直纹理和平行纹理两个方向对所选材料表面光泽度（镜面反射角60°）测试表明,玛瑙省藤材平行纹理方向表面光泽度测量值大于垂直纹理方向的测量值。

In this article, using color difference meter, the parameters of rattan surface color were measured, and discussed the distribution characteristic of color space for those parameters. The results showed that the range of lightness index distribution is narrow （L＊：73.59～79.29;V：6.25～6.78）, the parameters distribution range of chromatically index and color tone visual is narrow （a＊：5.82～6.45; b＊：19.86～21.83; H：7.77～8.27, the most part distribution is within yellow color tone system）, the range of saturation distribution is not wide （C：3.28～3.65; C＊：20.69～22.77）. The rattan surface gloss was measured in along and vertical grain, the gloss in along grain condition is bigger than that of in vertical.
