1·One source of error is refraction, the bending of light beams as they pass through air layers of different temperature and pressure.
误差的一个来源是折射，即光束通过不同温度和压力的空气层时发生的弯曲现象。
2·Light beams can carry more information than radio signals.
光束运载的信息比无线电信号运载的信息多。
3·Optical Beam Quality Factor of Nonparaxial Light Beams. I. Definition.
非傍轴光束的光束质量因子.I。定义。
4·It will add drama and will keep a little detail in the light beams themselves.
这样的效果会比较戏剧化，并且保留光柱本身的部分细节。
5·Under astigmatism even narrow parallel light beams will not combine into one point.
有象散存在时甚至很窄的平行光束都不能会聚在一点。
6·Optical fibers are also used in communication systems to transmit modulated light beams.
纤维束不具有完全在两个相同的对齐方式完光，但不是图像传输。
7·The colorful light beams on the stage make the atmosphere of the performance even more exciting.
舞台上五颜六色的光柱使演出的气氛更加热烈。
8·Thiel says generating multiple light beams with a microlens array could make the process even faster.
泰尔表示产生多个光束的带有微透镜阵列可以使该过程甚至更快。
9·Spectrometer with dual light beams takes significant role in molecular absorption spectrum measurement.
双光束分光光度计在分子吸收光谱测量中起着十分重要的作用。
10·This 'force' not only affects geometry, including the paths of light beams, but also the passage of time.
这种“力”不仅只影响几何体（包括光束的路径），也影响着时间的流逝。
