对比度

The spectral characteristics of the device were measured by an optical spectrum analyzer in a set-up with fiber coupling. A periodically vibrated resonance spectrum was observed with 10 dB contrast and 0.182 nm period. According to the experimental data and the theoretical formula of the ring resonator, transmission loss of 1.7 dB/cm in the ring resonator was obtained.

利用光谱仪对器件的传输特性进行了测量，观测到具有10 dB对比度，自由光谱范围0.182 nm周期性谐振现象，结合环形谐振腔的传输特性，得到环形腔具有较低的传输损耗1.7 dB/cm。

He 6500 UB delivers a vibrant, high contrast, crowd-pleasing picture, no question about it.

At the end of the chapter, the author tries to image the medium with large contrast, which is special important to metallic ore exploration.

在最后给出了作者在大对比度介质下的成像的尝试。这一点对金属矿勘探是有直接意义的。

Desaturated while kept in RGB mode, the image looks similar, but this is a better startingpoint even if we want to make quite simple adjustments to the tone and contrast of the image.

在RGB下降低饱和度，两张图看起来没多大差别，不过你要想对图片的色度和对比度做写简单的调整，这张图可是潜力巨大呢。。。

To create bump and specular maps I simply desaturated all the color map layers and changed their value and contrast accordingly, only minor local painting was required afterwards.

为了创建凹凸贴图和高光贴图，我简单降低了所有的色彩层的饱和度，根据需要改变它们的数值和对比度，然后在需要的地方做了小小的绘制。

High contrast beween shadow and light can create confusion and disorientating patterns for those with failing vision.For this reason,all interior spaces should be lit at a consistent and even level,floor to ceoling and wall to wall.Older people seldom walk down the center of a corridor,according to Dupuy,because they're afraid of falling."If the wall is not illuminated properly,that does not give them a lot of confidence,"he says.

高对比度beween阴影和轻，可制造混乱和disorientating模式，为有需要的人士未能vision.for这个原因，所有的内部空间应该点燃在一个一致的，甚至一级，请ceoling和围墙把wall.older人们很少步行中心一条走廊，根据dupuy ，因为他们怕落入&，如果这堵墙是不是发亮得当，不给他们一个很大的信心，&他说。
