| 释义 | 〔pallid〕Lacking intensity of color or luminousness.暗淡的：缺乏色度或亮度的〔chroma〕The aspect of color in the Munsell color system by which a sample appears to differ from a gray of the same lightness or brightness and that corresponds to saturation of the perceived color.色品，色度：曼塞尔色系中的色图，例如相同明度和亮度的灰色会由于可见色的饱和度不同而不一样〔faint〕Lacking brightness:黯淡的：缺乏亮度的：〔Adams〕American astronomer who developed a method of measuring the distance of a star from the earth by comparing its absolute brightness to its apparent brightness.亚当斯，沃尔特·悉尼：(1876-1956) 美国天文学家，提出通过比较行星的绝对亮度与表面亮度以测定行星与地球之间距离的方法〔comparator〕Any of various instruments for comparing a measured property of an object, such as its shape, color, or brightness, with a standard.精密度测量器：一种仪器，用于比较物体的可度量性质，例如按标准度量它的形状、颜色或亮度〔black〕The achromatic color value of minimum lightness or maximum darkness; the color of objects that absorb nearly all light of all visible wavelengths; one extreme of the neutral gray series, the opposite being white.

Also called international candle 国际烛光：一种旧式亮度单位，原来以一根有标准构成的蜡烛来定义，等于1.02坎德拉 也作 international candle〔fade〕To cause to lose brightness, freshness, or strength:使褪色：使失去亮度、新鲜或活力：〔bright〕Brilliant implies intense brightness and often suggests sparkling, glittering, or gleaming light: Brilliant 含有亮度很强的意思，常指闪耀的、闪烁的光： 〔millilambert〕A unit of luminance equal to one thousandth (10-3) of a lambert. 毫朗伯：亮度单位，等于千分之一(10-3)朗伯 〔brown〕Any of a group of colors between red and yellow in hue that are medium to low in lightness and low to moderate in saturation.棕色，褐色：一组介于红黄间的颜色，亮度由适中到低，色彩的饱和度由低到适中 |
