【摘要】 采用测色色差计对中国１１０种商品材树种的木材表面材色参数进行测量，讨论了这些参数的色空间分布特征，其结果（除去一个黑颜色树种乌木）为：明度指数分布范围较宽（Ｌ＊为３０—９０；Ｖ为２～８），色品指数和色调值参数分布范围较窄（ａ＊为－２～２０；ｂ＊为０～３０；Ｈ为２．５Ｒ～５Ｙ，大部分分布在ＹＲ色调系内），饱和度分布范围不宽（Ｃ＊为４～６；Ｃ为０．８～６．４）。其中针叶树材分布范围较窄，且多分布在高明度范围，并对１１０树种的木材表面光泽度（镜面反射６０°）分顺纹理和垂直纹理两个方向进行了测量和分布特征解析。无涂饰木材表面镜面反射光泽度较低，大多分布于１０％以下的范围，分布中心在５％左右。顺纹理入射与垂直纹理入射条件下的光泽度相比，前者较大，两者之间具有高度的相关性，其关系可用线性方程式表达。更多还原

【Abstract】 Using color difference meter, the parameters of wood surface color were measured for 110 tree species of China commercial wood, and discussed the distribution characteristic of color space for those parameters. The results indicated that the range of lightness index distribution is wide (L*:30 ～90; V:2～ 9),the parameters distribution range of chromatically index and color tone visual is narrow (a*:2～20; b*:0～30; H:2. 5 R～5 Y), the most part distribution is within YR color tone system). The range of saturation distribution is not wide (C*:4～ 6; C:0. 8～6. 4), which the distribution range is narrow for softwood, and most of these are in high lightness range. The wood surface gloss were measured for 110 tree species in along and vertical grain and its distribution characteristic was analysed. The reflection wood surface gloss in mirror is low for no cover with paint, most of distribution is blow 10%, the distribution center is in 5% or so. The gloss in along grain condition is bigger than that of in vertical, both of them have high coherency, and its relation ship is expressed by linear equation.更多还原
