Investigation of texture effect on visual colour difference evaluation

The texture effect on visual colour difference evaluation was investigated in this study. Five colour centers were selected and textured colour pairs were generated using scanned textile woven fabrics and colour‐mapping technique. The textured and solid colour pairs were then displayed on a characterized cathode ray tube (CRT) monitor for colour difference evaluation. The colour difference values for the pairs with texture patterns are equal to 5.0 CIELAB units in lightness direction. The texture level was represented by the half‐width of histogram, which is called texture strength in this study. High correlation was found between texture strength and visual colour difference for textured colour pairs, which indicates that an increasing of 10 units of texture strength in luminance would cause a decreasing of 0.25 units visual difference for the five colour centers. The ratio of visual difference between textured and solid colour pairs also indicates a high parametric effect of texture. © 2005 Wiley Periodicals, Inc.

Egg white powder in extruded fish crackers

Four levels of egg white powder (EWP), 0, 1.5, 3.0 and 4.5%, were added to fisfc cracker formulation consisting of tapioca starch, fish paste, and water. the mixture was extruded through a single screw extruder, and the extrudate was cut, dried, heated in a microwave, and the degrees of expansion, bulk density, colour and protein content were measured.
The addition of 1.5 and 3.0% EWP had no significant effect ( P < 0.01) on diametral and longitudinal expansion, however, 4.5% EWP significantly ( P < 0.01) reduced them. Bulk density and protein content of the final product increased as the percentage of EWP increased in the formulation. the total colour difference measurement showed a significant increase ( P < 0.01) in brown colouration at 4.5% EWP.     

关于彩涂压型钢板构件设计中的选材问题

近年来 ,在彩涂压型钢板构件设计应用中 ,由于不重视、不了解如何合理选材 ,在实际工程的材料订货中也都不提出对材料性能的技术要求 ,致使供货材质、材性不能满足使用要求 ,存在降低彩板构件承载力或减少其使用寿命的隐患 ,应引起设计人员的注意。同时对当前如何按使用条件及材料供应条件合理地选定彩板材料的性能技术要求 ,包括基板钢材的级别及力学性能、板厚及公差控制要求、镀锌层质量与彩涂层类别以及参照的技术标准等 ,提出了一些建议 ,供设计应用参考。最后还对板的强度、厚度以及镀铝锌板的选用问题进行了讨论
