apparent brightness

基本释义

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。
