摘 要：
测定分析了筒状非洲楝Entandrophragma cylindricum,古夷苏木Guibourtia tessmannii和水曲柳Fraxinus mandschurica木材醇酸清漆涂饰前后表面视觉性质的差异。结果表明,涂饰处理降低了3种木材表面的明度(L*)和红绿轴色品指数(a*)值,其中,古夷苏木的L*变化差异最大,明度降低明显;水曲柳的红绿轴色品指数差(Δa*)绝对值最大,相比处理前更偏向绿色;3种木材透明涂饰后的黄蓝轴色品指数(b*)均有所升高,黄蓝轴色品指数差(Δb*)绝对值由大到小分别为水曲柳>古夷苏木>筒状非洲楝,数值越大越趋于黄色;总体色差(ΔE*)变化差异不大,涂饰对3种木材的总体色差影响不明显。

摘 要：
Determinations were conducted on visual physics magnitude of Entandrophragma cylindricum, Guibourtia tessmannii and Fraxinus mandschurica wood before and after painting alkyd varnish. The results show that painting reduced the luminance(L*) and the chrominance(a*) of tested wood specimen, the biggest change L* was specimen of G. tessmannii wood with obvious decrease of luminance. The absolute value(Δa*) ofF. mandschurica wood was the largest, greener than that of untreated one. The chrominace(b*) of three kinds of wood specimen increased after painting, and the absolute Δb* was ordered by specimen of F.mandschurica > G. tessmannii > E. cylindricum. Chrominance aberration(ΔE*) of tested wood specimen had little difference before and after painting.
