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。
Galaxy redshift determination by use of principal component analysis and cross correlation .
主成份分析和交叉相关的红移测量。
Who exploded the cosmos : origin of gravitation and gravitational redshift .
谁引爆了宇宙:引力起源与引力红移。
The greater the amount of redshift , the more rapid the movement .
红移的量越多,移动的速度越快。
By lumping all these regions together , redshift cannot distinguish a variation of expansion rate in space from a variation in time .
这些区域都积累在一起了,所以红移并不能分辨出不同时刻下空间膨胀率的变化。
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。
Udfj-39546284 was seen at only one wavelength band , while macs 1149-jd was detected at five , giving scientists more data for making a better redshift measurement .
