light beam

基本解释

When the laser hits the photovoltaic device, the photons in the light beam are converted to electricity in the same way that solar cells convert sunlight into electricity.
当镭射光击打到光电装置上，光束上的光电子就会转化为电能，就像太阳能电池板把太阳能转化为电能。
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。
Using this model, Zhang and his team then designed a plasmonic waveguide with a 180 degree bend that won�t alter the energy or properties of a light beam as it makes the U-turn.
使用这个模型，然后张和他的团队设计了一个180度的弯曲，将不会改变能源或光束性能，因为它使掉头一电浆子波导。

This intense heat they project in a parallel beam against any object they choose, by means of a polished parabolic mirror of unknown composition, much as the mirror of a lighthouse projects a beam of light.
So, what we would expect is that there is a relationship between intensity in kinetic energy because it was understood that however intense the light was, if you had a more intense light, it was a higher energy light beam.
光强和能量之间,应该有一定的关系,因为在我们的理解中,不管光强是多少，光的强度越大,光束能量越高。

And this is a very fast speed, of course, it's about 700 million miles per hour. So, one way to put that in perspective is to think about how long it takes for a light beam to get from earth to the moon. Does anyone have any guesses? Eight seconds, that sounds good.
当然这是一个非常快的速度，它大约是每小时7亿英里,为了更形象化，我们,看看光从地球到月球,需要多少时间，你们猜猜是多少？,8秒，猜的不错。
