light beam翻译
light beam的基本解释
读音: 美: 英:
光束:光束是从光源发出的一束直线走向的定向光的集合。阳光经过云层、树叶或窗户等介质后可以形成光束(太阳光束);光束也可以由人工生成,在许多照明设备中,为了能发出光束,这些设备用到了电光源和抛物面反射器,例如前照灯、抛物面镀铝反射灯和发光二极管。
例句
To the astonishment of the entire world, the neutrinos clocked in 60 nanoseconds sooner than a light beam traveling the same distance would have done.他们记录到的中微子的行驶时间要比光线行驶相同距离提早了60纳秒,从而使整个世界为之震惊。Because light travels in a straight line through the contours of space-time, a light beam will curve where space-time curves, this curving was first measured in 1919.因为光沿时空走直线,所以光线在时空弯曲的地方会弯曲。这现象在1919年首次被观测到。
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。
