Hence it is proposed that the temperature and the density of electrons in a rich cluster and the Hubble constant H0 may be determined from the observations of the IR-background distortion.
因此，通过对畸变的观测，可以确定富星系团内电子的密度和温度以及哈勃常数h_0。
H0 is the Hubble constant, or parameter that indicates the rate at which the universe is expanding; and distance is the galaxy's distance from the one with which it's being compared.
其中，速度表示星系后退的速度，H0为哈勃常数，也即宇宙膨胀速率的参数，而距离指的是星系与相比较星系之间的距离。
