一束光

You can break up a beam of incoherent light with a prism, which is made of glass.

你能用玻璃制的棱镜分解一束非相干光。

Suddenly, I am conscious of a white beam of light, knowing that I must follow it or be lost.

突然，我意识到一束白光，我知道我必须跟从它，否则我就会迷失。

After enough of the bait has been eaten we send a beam of light through the desert.

当足够多的诱饵被吃了以后，我们送出一束穿越沙漠的光。

One slightly concave cylindrical lens combination is used to change one laser beam into small sector in small angle, and one reflector projects the laser beam to prism driven by a motor to rotate in high speed to produce one reciprocating and scanning small sector plane.

采用微凹柱面透镜组将激光光源发射的一束激光拉成具有微小夹角的小扇面，利用反射镜将此激光束透射到由电机驱动的高速旋转多面棱体上，使激光束产生一个小扇形往复激光扫描光平面。

This opens the possibility of a new type of cross modulation, where a beam of light at one of the absorption frequencies can turn on or off the light of the other.

这就可能制造出新型的交叉调制器，一束有特定吸收频率的激光能打开或关闭其它的光。

He lay awake, thinking such things over and over again, all night long, and I stood watching him from a dark corner, till the dayspring came and shook me out.

他就这样醒着，想呀想呀想了一整夜，我就在黑暗的角落这样看着，直到黎明的第一束光把我惊起。

By treating photorefractive spatial soliton as rays in geometric optics, the action of the diffusion effect on propagation of PR spatial solitons is analyzed.

把光折变空间孤子看作几何光学中的一束光线，研究了扩散效应对光折变空间孤子传播的影响。

An incident wavefront of light makes an angle of 60°with the surface of a pool of water.

一束入射光的波前和水塘表面成60°角。

He found himself sorrounded by a mystic white light...

他发现自己被一束神秘的白光包围着。。。

For easy to install and checkout optical instrument,here primarily introduces the basic principles and structure component of collimator,which is composed of object lens、divisional board and ground glass.

1引言根据几何光学原理，无限远处的物体经过透镜后将成像在焦平面上；反之，从透镜焦平面上发出的光线经透镜后将成为一束平行光。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
