其减弱的比率，与我们在上文中所阐述过的地面光照随距离减弱的规律是一样的，也就是说，与距离的平方成正比。
The ratio in which this light decreases, is precisely the same as that of the terrestrial light illustrated above, viz., according to the square of the distance.
阴影深度取决于光照方向和强度，以及物体和投影面的距离。
The qualities of a shadow depend on the light direction and intensity, as well as the distance between the object and the surface where the shadow is cast.
C街道距光源的距离是A街的3倍，那么光线的昏暗程度将是A街的9倍，因为3X3 = 9，也就是说C街的光照强度只等于A街的1/9，如果这里要看清书上的字，字体就要扩大九倍。
" C " street is three times as far from the light as "A" street; hence it will be nine times darker there, for 3X3 = 9.
所以一个行星上要有足够的温度，那么这个行星距恒星的距离就得比它距离太阳的距离近，这样，这个行星上才能具备合适的温度，维持一定的光照和液态水。
So to have the same temperature, a planet needs to be much closer to that star than it would be from the sun, where you'd have a temperature where you might have light and liquid water.
如果一个光源照亮某一个地方，这个地方距离光源越远，光照强度会越弱，但是光照强度并不是与光源距离等比例地减弱，就是说，距离延长两倍，光照强度并不是减弱两倍，而是减弱两倍的两倍，等于减弱四倍；
If a light illuminates a certain space, its intensity at twice the distance is not twice as feeble, but two times two, equal four times, as feeble.
金星离太阳的距离排列第二，与地球相比是1:1.33，它受到的光照强度是地球的大约2倍。
Venus, the third planet, is one and a third times nearer to the sun than we are.
设置为仅实时的灯光永远不会被烘培。近端光照图作用于质量设置中的相对摄像机最小阴影距离范围内。
Realtime Only lights are never baked. The Near lightmap set is used within the distance from the camera smaller than the Shadow distance quality setting.
以豪斯多夫距离为相似性度量，提出了一种对光照及背景变化具有鲁棒性的快速准确多人脸检测算法。
This paper provides a fast and accurate algorithm of multi-face detection that is robust to the change of background and light.
该场景在双重光照贴图模式中烘焙和渲染：阴影距离以外的建筑物完全由光照贴图产生照明，而两个假人由实时灯光产生动态光照，但是不投射阴影；
The scene is baked and rendered in dual lightmaps mode: behind the shadow distance buildings are fully lit only by lightmaps, while the two dummies are dynamically lit but don't cast shadows anymore;
厂区、体育馆、码头、广告牌、建筑物、停车场以及其他需要室外远距离投光照明的场所。
Factory, sports hall, pier, bill board, building, parking lot and other places where outdoor long-distance flood lighting is needed.
毫无疑问，设置在纽约三一教堂塔顶的巨大光源照亮A街应该是没有问题的，也就是说，我们假定在这个离光源隔着一个广场的距离的地方，那里的光照程度是可以不费劲地读书看报。
We will take it for granted that the great light on Trinity steeple shines so bright, that one is just able to read these pages at a square's distance, viz. , on " A " street.
在激光半主动末制导炮弹武器中，激光照射器的有效照射距离对武器系统的作战效能有着很大影响。
Available irradiation range of laser irradiator influences the efficiency of weapon system of laser half initiative end guilding shell.
