为给非荧光纺织品白度评价优选出最接近人眼色觉的白度公式,采用白色辨识实验从自制非荧光织物中挑出白色样品,再分别挑选28个和85个样品开展成对比较法和类别判定法2种心理物理学实验,处理1万余个视觉评价数据,与9个白度公式的计算白度值作对比和统计分析,综合评价白度公式的预测性能。结果显示:以成对比较法评价白度公式时,亨特2(Hunter2)白度公式效果最好;以类别判定法评价白度公式时,Hunter2白度公式依然最好;2种评价方法结果一致,对于本文所用非荧光织物,原适用于评价荧光织物的Hunter2白度公式与人眼色觉的一致性最优。 相似文献

Complex of europium (Ⅲ) with maleic acid, and binuclear complexes of europium(Ⅲ)with maleic acid doped with non-fluorescent ions gadolinium, lanthanum and yttrium, were synthesized. The compositions and structures of complexes were characterized with elemental analysis, single crystal X-ray diffraction, IR and DSC-TG. Fluorescent properties were studied with fluorescence spectrum. The results indicated that the strongest fluorescent complexes were obtained when the ratio of europium and non-fluorescent ion was 8:2. The order of Eu^3+ fluorescence strengthened by three doped rare earths was Gd^3+ 〉La^3+ 〉Y^3+ 相似文献
