Colors of some small figures on colored grounds

Examination of the receptive field structure of the retina suggested looking at small graphic figures of special forms. The luminance distribution called the “Mexican hat function” was approximated by a black dot with a small white dot at its center, called a “tip,” and the inverse function was approximated by a white dot with a small black dot at its center, called a “pit.” Such figures were given the generic name “tippit.” On a dark‐blue ground, tips looked yellow, and on a bright‐yellow ground, pits looked blue. Similarly, a black line with a white center, on a blue ground, and a white line with a black center, on a yellow ground, elicited these effects. On yellow and blue grounds, simple, small colored dots looked more like the color of the ground than when seen as large spots on a neutral gray ground, an effect here called “microspreading.” This effect may be attributable to scattering and blurring, but these processes do not account for the tippit effects. The visual system exaggerates contrast between a large spot and ground, and diminishes contrast between a small dot and ground, but exhibits neither effect on a figure of some intermediate size. Chromatic pit lines exhibit effects obeying laws of additive mixture. It appears that perceptions of these effects are normally repressed. No causal link was sought or established between receptive field theory and the observed effects. © 2003 Wiley Periodicals, Inc.

全色彩环保油墨

通过分析油墨的基本组成可知：溶剂对环境的影响最大。与矿物油、植物油相比,源于木材加工业的松浆脂肪酸酯在油墨中作溶剂,其化学结构、黏度及挥发性能具有很多优点。而且,所制成的植物油型油墨在胶印性能、生物降解、气味、提高印刷效率方面效果极佳。目前,在环保要求与资源可再生性利用的压力下,植物油型油墨必将越来越受青睐。

Rheological Behavior of Coating Colors: Influence of Thickener

In this work we have investigated the effect of rheology modifiers on the rheological properties of concentrated (65 solids mass%) kaolin suspensions and six different coating colors. Measurements have been performed on kaolin‐based suspensions, without rheology modifier and with either a classic cellulose thickener or associative polymers. It was noticed that suspensions containing a thickener had a much larger viscosity and storage and loss moduli than suspensions containing no rheology modifier. The enhancement of the rheological properties was found to be much more important for the suspensions containing the associative polymer. These observations have been related to steric stabilization of the suspensions, and to the occurrence of entanglements and bridging when the associative polymer was used as the thickener. The influence of the thickener on the rheological properties of the coating colors was found to be similar to that observed for the concentrated kaolin suspensions.

Perceived density,a further attribute of color,revealed by the colors favored in Japan

Colors can be characterized by three main attributes: hue, value, and saturation. But colors also exhibit other phenomenological qualities. In this study, we identify one such secondary attribute of color: perceived density. We discuss the prevalence of dense colors in Japan starting from the “48 Teas and 100 Mice” colors of the Edo period, and develop the concept of perceived density through this aspect of Japanese color preference. When vivid colors were forbidden to commoners during the Edo period, subtle variations of brownish and grayish colors were created. These colors with base tones were not salient, yet they looked dense. Muted colors with paradoxical richness are still common in Japan today. Japanese commodity design often uses muddy colors with white or gray undertones, and deep colors with black undertones. Together they form distinct groupings of relatively dense color. The perceived density of color corresponds to how dense and filled, or thin and airy a color appears. Colors of higher perceived density appear to be more packed and to have mass. Perceived density of color is unusual in that it does not have a monotonic relationship with one of the primary perceptual attributes. High apparent density is observed in a central region of an equi‐hue plane where value or saturation are at intermediate values. We consider two possible explanations of how high values of density can coincide with middling values of value and saturation: characteristics of the spectral reflectance curves, or the complexity of the neural signals that underlie the emergent property.     

Colour Measurement of Human Teeth and Evaluation of a Colour Guide

In the present work the colour coordinates have been obtained in the CIELAB system (L*,a*,b*) for the teeth of 600 individuals. to determine the region of the CIELAB space which contains all the different hues found in human teeth. In addition. one of the colour guides most used in dentistry has been studied to compare the hue range in this guide with the range possible in human teeth. The results show that colour coordinates of human teeth fall within an elliptical contour centered in a yellowish white. The colour guide studied did not cover all the possible values found for teeth chromaticities.

气-固流化床压力波动功率谱指数衰减与阵发性混沌行为探讨

根据功率谱低频发散与阵发性混沌本质之间的联系，通过分析压力波动信号的功率谱指数衰减，并结合互信息函数分析，证实了流态化动力学所具有的阵发性混沌特性. 研究表明，随气速增加，压力波动层流区时间长度逐渐缩短，混沌越来越频繁地阵发，最终通向完全混沌状态. 此外，研究了层流区时间长度与雷诺数之间的关系，表明层流区时间长度随气速增加呈指数衰减，流态化动力学呈现出I型阵发机制.
