light beam

常見例句

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.
當鐳射光擊打到光電裝置上，光束上的光電子就會轉(zhuǎn)化為電能，就像太陽能電池板把太陽能轉(zhuǎn)化為電能。
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.
時空漣漪使得用光束測量的距離像引力波通過那樣變化，同時使得落在光電探測器上的光量發(fā)生變化。
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.
使用這個模型，然后張和他的團隊設(shè)計了一個180度的彎曲，將不會改變能源或光束性能，因為它使掉頭一電漿子波導(dǎo)。

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.
光強和能量之間,應(yīng)該有一定的關(guān)系,因為在我們的理解中,不管光強是多少，光的強度越大,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.
當然這是一個非常快的速度，它大約是每小時7億英里,為了更形象化，我們,看看光從地球到月球,需要多少時間，你們猜猜是多少？,8秒，猜的不錯。

His quest began in 1895, when as a 16-year-old he imagined what it would be like to ride alongside a light beam.

Operators can also hold the switch down to run the flashlight in low mode, producing a 50 lumen light beam and a longer 12 hour runtime.
