光线

Long-sightedness can be corrected with a convex lens that ensures light rays fall on the retina and focus accurately.

长期近视可以纠正一个凸透镜，确保光线落在视网膜和重点，准确。

The parallel light rays of the prnicipal axis that approach a convex lens can converge to the focal point.

只有在近轴光线条件下，平行光通过凸透镜才可近似聚焦于一点。

The system is the reflection of light through the cornea to determine each other's eye.

该系统是通过角膜反射的光线来确定对方的视线的。

In this sharp composite from the Hubble Space Telescope, Fomalhaut's surrounding ring of dusty debris is imaged in detail, with overwhelming glare from the star masked by an occulting disk in the camera's coronagraph.

在这幅来自哈勃空间望远镜的精细合成图像中，北落师门周围的尘埃环的碎片能够精细展现，并且在相机的日冕观测仪下，能够观测到被一神秘圆盘遮蔽的恒星发出十分耀眼的光线。

COROT, the first space observatory designed to search for planets beyond our solar system, captured its "first light" yesterday.

第一个用于寻找太阳系外行星的空间天文台CORTO昨天捕捉到了它的第一缕光线。

I should like to see how your theory, even if we waive the difficulties, explains those phenomena which are so clear and understandable in the light of the corpuscular theory. Take, for example, the fact that light rays travel in vacuo or in air along straight lines.

即使我们撇开那些困难，我还想知道你的理论如何去解释那些被微粒说解释得很明白而容易理解的现象，例如光线沿直线在"真空"或空气中通过的情况。

Gloss is associated with the capacity of a surface to reflect more light in some dirctions than in others.the directions associated with mirrorreflection nor mally have the highest reflectances,measurements by this test method correlate with visual observations of surface shininess made at roughly the corresponding angles.

Since environment of outdoor is complex, and light is not easy to control it is difficult and time-consuming to get correct corresponding points.

由於室外环境的复杂，光线强度不易控制，在室外影像中找到正确的对应点匹配是困难且花费时间的。

"They'll still be out there," says cosmologist Professor Lawrence Krauss of Case Western Reserve University ."But space will be expanding faster than the speed of light," and so the light from those galaxies will never reach us again.

凯斯西储大学的宇宙学家劳伦斯·克劳斯教授说："那些星系团还在，但是空间膨胀的速度比光速还快，因此那些星系团的光线将永远无法到达我们地球。"

MIGUEL DE CERVANTES is tall and thin, a man of gentle courtliness leavened by humor.

当楼梯上面的门打开，光线照进狱窖的时候，所有的声音和动作都停下了。
