英语释义

1. a displacement of the spectrum of a celestial body toward longer wavelengths that is a consequence of the Doppler effect or the gravitational field of the source also a measurement of a celestial body's redshift equal to the ratio of the displacement of a spectral line to its known unshifted wavelength and used especially to calculate the body's distance from earth

gravitational redshiftIn astrophysics, gravitational redshift or Einstein shift is the process by which electromagnetic radiation originating from a source that is in gravitational field is reduced in frequency, or redshifted, when observed in a region of a weaker gravitational field. This is a direct result of Gravitational time dilation - as one moves away from a source of gravitational field, the rate at which time passes is increased relative to the case when one is near the source.

英汉例句

• After all, only with the correct parameters that convert redshift to position would the reconstructed distribution be spherical.

  毕竟只有在正确的将红移变换为位置的参数下，重建结果才会是一个球形。

• With the Hubble Space Telescope it might be possible to find some galaxies up to redshift 10, but these objects are expected to be very rare and extremely faint.

  利用哈勃空间望远镜可能会找到一些红移值达到10的星系，但这些天体应该很罕见并且极其微弱。

• The power of this massive cluster telescope has allowed astronomers to detect a galaxy at the distant redshift of 5.58.

  这巨大质量星系团望远镜的强力使天文学家探测到了一个红移5.58的遥远星系。

• Everything is shifting, because the universe is expanding. It「s just easier to see Hydra」s redshift because the farther a galaxy is from our own, the faster it is moving away.

  在无数遥远的星系中，并非只有长蛇座才显示出红移现象，由于宇宙一直在膨胀，所有的东西都在移动，之所以能较容易地观察到长蛇座的红移，是因为星系距我们越远，其远离我们而去的速度就越快。

• 「This galaxy is just beautiful,」 says Yuan. 「Normally, galaxies at that redshift appear as blobs.」

  「这个星系很美丽，」Yuan如是说道，「通常，具有这么大红移量的星系只有小斑点那么大。」

• And redshift depends on just how the universe is expanding.

  并且红移取决于宇宙如何膨胀。

• Such a high redshift indicates the galaxy is 9.3 billion light years away, so we see it just 4.4 billion years after the Big Bang.

  这样的一个高红移量表明这个星系距离我们93亿光年，所以我们现在看到的它是宇宙大爆炸44亿年之后的它。

• 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。

• The latest observations, which reach a redshift of about 2, are consistent with dark energy having been around in more or less its current form for the past 10 billion years.

  最近达到了红移为2的观测与过去一百亿年中暗能量一直大约在目前状态下相一致。

• In fact, ever since the discovery of this phenomenon, whenever astronomers cannot measure a galaxy「s distance more directly they instead give an estimate using its redshift as a proxy.

  事实上，从那以后，当天文学家无法找到更直接的测量星系距离的方法时，他们会以红移来代替。

• The universe as it appears today is redshift 0. Redshift 1 refers to when the universe was half its present age.

  当宇宙为目前一半的年龄时的红移值为1。

• It」s sort of pioneering in many ways, because doing this kind of detailed study of a galaxy at a very high redshift is extremely difficult.

  AndrewBenson说，「从多方面看，这都是一种开创，因为对具有高红移的星系做这种详细的研究是非常困难的。」

• 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。
