redshift造句

• The redshift means that the quasars are very far away, more distant than the most distant galaxies we can see .
  红移意味着类星体是非常非常遥远的天体，比我们观测到的最遥远的星体还要远。
• We measure the redshift by the following parameter ,
  我们通常用z来表示红移的幅度：
• Linear redshift distortion in galaxy survey
  星系巡天中的线性红移畸变效应
• The cosmological redshift is not a normal doppler shift
  宇宙学的红移并不是平常的都卜勒偏移。
• The greater the amount of redshift , the more rapid the movement
  红移的量越多，移动的速度越快。
• Misunderstandings about the relation between redshift and velocity abound
  关于红移与速度之间的关系，也有不少误解。
• This effect , known as gravitational redshift , is not specific to black holes
  这种称做重力红移的效应，并不是黑洞所特有。
• In high - redshift galaxies , however , the rate of star formation is 10 times as great
  但是，在高红移的星系中，恒星形成率是这个数目的10倍之多。
• The doppler redshift and the cosmological redshift are governed by two distinct formulas
  都卜勒红移和宇宙学红移是由两个截然不同的准则所支配。
• Their spectra show large amount of redshift indicating that they are very far away from us see
  它们的频谱有极大的红移显示它们离我们极之遥远请参阅
• Astronomers estimate the speed at which a galaxy is moving away by measuring the galaxy ' s redshift
  天文学家通过测量星系的红移对其退行的速度进行估算。
• If the redshift is much less than 1 , we can calculate the receding velocity by the following formula
  若红移z比1少得多则我们便可用以下公式找出星系的退行速度v ：
• A redshift can be measured when light from a galaxy is broken up and spread out into a band of colors called a spectrum
  当从星系发出的光被分解展开成光谱的时候就可以测出红移了。
• The redshift is an apparent lengthening of electromagnetic waves emitted by an object moving away from the observer
  一个正在远离观察者的物体所发出的电磁波长度变长的现象就是红移。
• What is specific to black holes , however , is that the redshift becomes infinite as the travelers approach the horizon
  不过黑洞特殊的地方在于，随著旅人向视界趋近，红移会变成无限大。
• The standard way to perform this task is to obtain a spectrum of each galaxy in the image and measure its redshift
  这项工作的标准做法，是取得影像中每个星系的光谱并且测量它们的红移。
• The redshift is due to doppler s effect . thus , a galaxy having positive z means that it is receding from us
  红移是由多普勒效应造成的，所以星系红移越大，表示它正以更高的速度远离我们。
• The redshift caused by the expansion is often confused with the more familiar redshift generated by the doppler effect
  膨胀所造成的红移，常会和我们比较熟悉的都卜勒效应所产生的红移搞混。
• In fact , astronomers usually talk in terms of redshift rather than years , because redshift is what we measure directly
  实际上天文学家通常不用年为单位，而是用红移，因为红移是我们直接测得的物理量。
• What hawking did was to reconsider the implications of the infinite redshift when the quantum nature of light is taken into account
  霍金所做的，是在把光的量子性考虑进来，重新思考无限红移所衍生的结果。
