The color of the bottom surfaces of the recesses is set to brightness relatively lower than the brightness of the color of a board surface (18).
本文分析了BAM蓝粉的合成温度、时间参数与相对亮度、粒度等性能指标之间的关系。
We analyzed the relation between the comparative brightness, granularity of BAM blue phosphor and synthesizing temperature and time.
采用YUV颜色模型，分析了各LED像素点的相对亮度值，对亮度不一致的像素点进行筛选与记录；
The YUV color model is used to analyze the relative luminance values of various LED pixels, to screen and record each LED pixel that luminance are not uniform;
对后处理工艺进行了优化，通过弱球磨，有效地降低了BAM蓝粉的粒度，同时相对亮度没有明显降低。
We optimized the after-disposing technology and found an effect ball-grinding way to make the granularity of BAM blue phosphor decline under the condition of keeping the high comparative brightness.
同时，三种数值的排列简化了图片的复杂性，所以即使一个视频质量差或色相不一，关于视频的相对亮度信息还能保留。
At the same time, the array of three values simplifies the complexity in the image, so even if a video is of poor quality or a different hue, the information about its relative luminance is retained.
许多人常常把焦比和图像亮度等同。其实严格来说，只有当观察月亮和星云等“扩展”光源(译者注：与点光源相对，可以理解为面光源)的时候，上述说法才是正确的。
Many people equate focal ratios with image brightness, but strictly speaking this is only true when taking pictures of "extended" objects like the Moon and nebulae.
通过对比遥远的超级新星和附近超级新星的亮度，科学家们发现遥远的超级新星相对而言比近的要暗淡25%左右。
By comparing the brightness of distant, far-away supernovae with the brightness of nearby supernovae, the scientists discovered that the far-away supernovae were about 25 percent too faint.
随着相对方位的变化，反射光亮度也随之变化，有时亮度的变化是突然发生的。
As relative orientations change, the brightness of reflections may also change, sometimes suddenly.
然而，大爆发后，黑洞进入了另一个相对黑暗的状态，但是仍比2006年前的平均亮度要高出10倍。
After the outburst, however, the black hole entered another relatively dim state, but was still about ten times brighter on average than prior to 2006.
利用一种直接由天空亮度的相对分布反演气溶胶光学特性的方法。
We propose a method to retrieve aerosol optical characteristics directly from the distribution of sky brightness.
但是，因为这些主星的亮度相对偏淡，所以它们可能没有足够的高温令系外行星的主体结构气化。
Yet because the host stars are relatively dim, they may not have been hot enough to boil away the building blocks of exoplanets.
与物体表面亮度的主观感觉相对应的客观物理性质。
The objective physical property corresponding to the subjective sensation of the brightness of a surface.
应用四点积分标准评价所有弹性图像的病变可视性、相对明亮度、边缘规则性和有限性。
All elastograms were evaluated for the lesion visibility, relative brightness, and margin regularity and definition by using a four-point scale.
