尽管，许多卫星在36000千米处形成一个类似土星光环的环，但这个高度的卫星都需要花费24小时绕地球一圈。因此，它们一直在地球上空的同一点盘旋。
Many, though, form a ring like Saturn's at a distance of 36,000km, the place at which an object takes 24 hours to orbit the Earth and thus hovers continuously over the same point of the planet.
该人造卫星每100分钟绕地球旋转一圈。
The satellite revolves around the earth once every hundred minutes.
由于地球自转速率发生偏离，因此当把地球绕中轴旋转一圈作为一个单位时，（这种偏离）就相当于一秒钟时间。
Since Earth’s rotation rate varies, so would the value of one second when it’s defined as a fraction of the time it takes for one spin of the Earth on its axis.
这里所谓的一年也没什么特别,就是地球绕太阳一圈的时间,和金融没什么关系,我们只是习惯这么用
Now, there's nothing special about annual-- that's the time it take the Earth to go around the sun, but it doesn't have any relevance to finance-- but we are just accustomed to using that.
