计算机配色算法的改进 总被引:1,自引:1,他引:1
以活性染料对纯棉织物染色为例,在建立的基础数据库上,计算机配色是利用染料的三刺激值对霜一浓度的对应单位浓度的K/S值进行配色计算,对于任意染制标样,通过测色及配色计算,均可得到色差在要求范围内的配方。 相似文献

The major objectives of this study were to develop high‐fiber toast bread formulations with lighter crumb color and to evaluate the CIE tristimulus system to measure the color of crumb as affected by the addition of various flour mill fractions. The optimized straight‐dough bread making method (AACC method 10‐10B) was used for conducting the baking trials. CIE L* a* b* values of the crumb were measured. Additional color attributes, (whiteness value, redness index (RI), saturation index (SI) and total color difference (ΔE), were calculated from these L* a* b* values. Compared with flour samples, the germ and bran fractions had significantly lower CIE L* a* b* and whiteness values, but higher redness and saturation indices, indicating darker color and hue for the latter. Test bread samples having up to 30% bran and 10% germ, were lighter in crumb color than the control whole wheat flour bread. It was concluded that high‐fiber toast bread, with lighter crumb color than whole wheat flour bread, can be produced by using white flour, and equal proportions of coarse and fine bran at 20%, germ at 5%, and sodium stearoyl‐2‐lactylate at 0.5% levels. The CIE L*a* b* tristimulus system can effectively be utilized for distinguishing crumb color variations in toast bread samples. 相似文献

SUMMARY– Pairs of hams from 72 crossbred barrows slaughtered at three weight intervals (68.2, 90.9, and 113.6 kg) were assigned to three treatments of glucono delta lactone (GDL) (0, 30, or 60 g/l) and two post cure aging periods (1 or 14 days). Following post cure aging, samples from the boneless hams were exposed to light (200 ft-c) for various time intervals (0, 30, 60, 90, 120, 150, 180, and 1440 min) and nitric oxide- and total-pigments extracted with acetone/water and acetone/acid respectively. There were no significant differences in color formation or color stability of hams aged 1 or 14 days. The influence of GDL on nitric oxide- and total-pigment formation and stability was nonsignificant at most exposure intervals. Chemical analysis showed a significant decrease in moisture content of hams with increasing amounts of GDL added. Fat, chloride, and ash levels were not different for the three GDL treatments. Residual nitrite levels were found to be significantly lower for the 30 g/l of GDL in hams extracted one day post cure. 相似文献

翡翠透明度测量和分级 总被引:2,自引:0,他引:2
赵明开 《宝石和宝石学杂志》2000,2(3):4-7
透过率(T)是透过光强与入射光强的比值。不同物体的透明度只能在相同厚度下才能比较。建立了1mm厚的物体对光的透过率作为表征透明度的基本单位,称为单位透过率,用t表示。单位透过率和厚度为n的物体的透过率的转换公式为:t=n√T。只须测量物体厚度及该厚度的透过率通过计算就可以得到t值。在前人悲翠透明度定性分级的基础上,提出了悲翠透明度定量测量和分级的方法。 相似文献

探讨了瓶用聚酯切片色相的测试方法。通过对不同粒径瓶用聚酯的色相对比实验,发现粒径的变化会导致L、a、b值及测试的标准偏差产生明显变化。20-40目粉末法值与切片法值相比,L值高约4-5,a值低约1,b值高约0.5,而标准偏差则分别减小到0.028、0.132、0.045,这说明粉末法有利于提高瓶用聚酯切片色相的测试精度。 相似文献
