recession rate meaning in Chinese
退离速率
Examples
- 513km s mpc , ie , for a celestial object 1 , 000 , 000 parsec away from us , its recession rate is 513km 1 parsec 3 . 26 light years
513 km s mpc ，即一个距离我们一百万秒差距的天体，它的退行速度是每秒513公里一秒差距3 . 26光年。 - From hubble s law , we know that measurement of recession rate of celestial objects mostly clusters of galaxies and distances are the pre - requisites for the search of h
，先要测量出天体主要是星系团的退行速度和距离。哈勃本人在1929年给出第一个数值： h - American astronomer edwin hubble in 1929 discovered that the recession rate of galaxies was directly proportional to their distance . this is what we call the hubble s law which defines that v h
美国天文学家哈勃于1929年发现星系退行速度与其距离存在著正比的关系，即所谓哈勃定律：退行速度v h
