近义词:光年
光(电磁波)传播的速度。一般指光在真空中的传播速度。各种频率的光在真空中的速度都一样,为299 792 458米/秒,是自然界重要常数之一。光速在任何惯性系中都等于这一常数,任何物体的速度都不能超过光在真空中的速度。在介质中,各种频率的光传播速度各不相同,但都比在真空中小。
If that were true for galaxies, the most distant visible objects in the sky would be receding at velocities just shy of the speed of light.
如果这对于星系也是正确的,那麽天空中可见的最遥远物体,就会是那些远离速度仅仅略小于光速的天体。The light speed control behavior of the resonator with gain is calculated and compared with that of the resonator with loss.
计算了带有增益的微环谐振器的光速控制行为,并与带有损耗的微环谐振器进行对比。If a rocket was one day able to travel at a tenth of the speed of light, it would take 200 years to make the journey.
如果有朝一日,人类能乘坐以十分之一光速飞行的火箭进行星际旅行,抵达Gliese581g需要花费200年。One twitch of the finger is all it takes to dispatch missives to the next continent or the next cubicle at light speed.
手指一动,不管是相邻的大洲,还是相邻的办公隔间,大批的邮件都能以光速送达。Because information cannot be conveyed faster than light, the horizon defines the sphere of influence of any physical mechanism.
由于资讯的运载与传播不能比光速快,视界因而限定了物理机制所能影响的范围。Moving to the other end of the scale, our ancestors never had to navigate through the cosmos at speeds close to the speed of light.
再谈一谈尺度的另一端,我们的祖先从来不需要在一个接近光速的宇宙中操纵自己的身体。Since the speed of light is well known, any delay in receiving the satellite's signal can be converted into a distance.
由于光速广为人知,接受卫星信号时的任何时间迟缓都能折算出距离的远近。If spaceships that can fly faster than the speed of light were built, a day on board would be equivalent to a year on Earth.
如果太空飞船的速度能超过光速,船上的一天将相当于地球上的一年。It travels at 186, 000 miles per second and behaves as if it were both a solid particle and a wave of energy.
光速可达每秒钟186,000哩,而且光的传播不但是固体的粒子,又是一道能量。
