1·The space-time ripples cause the distance measured by a light beam to change as the gravitational wave passes by, and the amount of light falling on the photodetector to vary.
时空涟漪使得用光束测量的距离像引力波通过那样变化，同时使得落在光电探测器上的光量发生变化。
2·And even more interesting; what if semi transparent, coloured material occurs in some areas and partially blocks the light beam?
而且更有趣，如果是半透明，有色物质会发生在一些区域和部分被阻隔的光束里？
3·A small laser in each of the 64 access points in the skull caps shines a light beam that penetrates about 2.5 centimeters into their brains.
头盖帽上有64个接入点，每个接入点里面都有一个小型激光器，他们发送的光束可以穿透到大脑2.5厘米之下。
4·The light beam can be steered more accurately than a mechanical cutter.
这种光束比机械切削器能运转得更为精确。
5·The Goos-Hnchen shift of the transmitted light beam in a two-prism configuration is investigated by stationary-phase approach when the incidence angle is less than the critical angle.
利用稳态相位法研究了当入射角小于全反射临界角时双棱镜结构中透射光束的古斯汉欣位移。
