光线

There is a suggestion in the data that productivity was more responsive to changes in artificial than natural light.

数据表明，较自然光线相比，生产力更易随着人为的日光灯光线来改变。

As light rays enter your eye, your cornea refracts -- bends back -- the rays to focus them on your retina, which is the back part of the eye.

由于光线进入你的眼睛，您的角膜折射-弯回-光线集中在您的视网膜，这是回一部分的眼睛。

A beam of white sunlight entering a snow bank is so quickly scattered by a zillion ice crystals and air pockets that most of it comes zinging right back out of the snow bank.

当一道白色阳光进入一团雪时，光线很快被大量的雪的晶粒和空气包分散以致大部分的光线都刷刷地反射到雪团外面了。

The light in this world is purest, brightest silver, brighter than the flash of an arc welder.

这个世界的光线是极度纯粹、极度明亮的银光，比电焊闪光更亮的光线。

In a camera, light rays pass through a series of lenses that focus images onto film.In a healthy eye, light rays pass through the cornea and lens, which focuses images onto the retina, a layer of light-sensing cells lining the back of the eye.

在照相机中，光线经过一系列的透镜，把图像聚焦在胶片上，在健康的眼睛中，光线通过角膜和透镜，把图像聚焦到视网膜上，而视网膜是一层排列在眼底的光敏单元。

The two lamps on the chimney piece, which had shades of rose-colored lace, cast a feeble light over them while on scattered pieces of furniture there burned but three other lamps, so that the great drawing room remained in soft shadow.

壁炉上的两盏灯，罩着粉红色的灯罩，发出微弱的光线，把她们照亮；在远一点的几件家具上，只有三盏灯，宽敞的客厅沉浸在暗淡而柔和的光线里。

The dark band of dust that obscures the mid-section of the Sombrero Galaxy in optical light actually glows brightly in infrared light.

在普通光线下黑暗的尘埃带让草帽星系中间截面模糊不清，但在红外光线下能看到那里却发出明亮的光。

With this approach, exploiting image-space coherences for primary rays in ray tracing is straightforward.

利用该算法，光线跟踪中主光线在图像空间的相关性可以方便、直观地被利用。

It will decrease when the pointing angle increases,and vice versa.By giving a pixel size of 20 μm for a detector,an orbit altitude of 600 km and a beam deflexion angle low than 30° for the imaging spectrometer, the effective focal length of the telescope was calculated(400,470 or 435 mm),and the relation curves between the relative ratios of ground resolution and the beam deflexions were presented.

给定成像光谱仪探测器像元尺寸为20 μm，飞行轨道高度为600 km，光线摆角≤30°，以星下点、最大摆角和整个运动补偿段地面分辨率中值为30 m为依据来计算望远系统的焦距，求得望远系统焦距为400、470、435 mm，并给出了此时的地面分辨率相对比值与光线摆角的关系曲线。

The pupil diameter of different diopters changes greatly under different rays, and it is a very important parameter to measure the pupil diameter in different diopter under different rays before the refractive surgery.

不同屈光度在不同光线下瞳孔直径有很大的变化；不同屈光度在不同光线下的瞳孔直径是屈光手术前评估的一个重要参数。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
