[天] 视亮度；表观亮度

The object's apparent brightness yields the distance; its redshift yields the velocity.

这些天体的视亮度可以得到距离，它们的红移可以得出速度。

The distance to such an object can be worked out by comparing its apparent brightness with its known, absolute brightness.

经过比较表观亮度和已知的绝对亮度，即可得出该天体和我们的距离。

Deferring to historical custom, astronomers, measure the apparent brightness of stars through the magnitude scale, a very confusing way.

按照历史习惯，天文学家用星等标这种容易使人混淆的方法来度量恒星的视亮度。

That unexpected finding was the result of studies of supernovas whose apparent brightness (and therefore distance) did not match the previous theory.

这个出乎意料的发现是因为发现超新星的亮度(表示距离)和以前的理论不相符。

This is the first study in the world to use the reflection of the Earth to measure the effect of continents and oceans on the apparent brightness of a planet.

这是世界上首次利用地照来研究陆地和海洋对行星表面亮度的影响。 在其他研究中，已经使用色谱和红外传感技术来确认植物以及进行气候监测。
