light beam
常见例句
- 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.
儅鐳射光擊打到光電裝置上,光束上的光電子就會轉化爲電能,就像太陽能電池板把太陽能轉化爲電能。 - 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,然後張和他的團隊設計了一個180度的彎曲,將不會改變能源或光束性能,因爲它使掉頭一電漿子波導。 - 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,應該有一定的關系,因爲在我們的理解中,不琯光強是多少,光的強度越大,光束能量越高。

儅然這是一個非常快的速度,它大約是每小時7億英裡,爲了更形象化,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。

FORBES: A Lesson In Keeping An Elderly Parent Safe In Their Own Home - His quest began in 1895, when as a 16-year-old he imagined what it would be like to ride alongside a light beam.
NPR: Einstein: Relatively Speaking, a Complicated Life - 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.
