莫巴舍尔教授及其团队确定了组成该星团的星系并测量了它们的距离和速度。

Professor Mobasher and his team identified member galaxies of this cluster and measure their distances and velocities.

距离和速度对中级跑步者是最好的，但是你可以根据你的跑步水平更改速度。

The distance and speeds are best for intermediate runners, but you can change the speeds based on your running level.

然而，事实上从双方的度量距离和速度的变化方面来说，到地球的距离是相等的。

They are, in effect, equidistant from the Earth in terms of both metric distance and velocity change.

So, we can just plug it in. Speed is equal to the distance traveled, which is lambda over the time elapsed, which is 1 over nu. so, we can re-write that as speed is equal to lambda nu times nu, and it turns out typically this is reported in meters per second or nanometers per second.

经过的距离和所花的时间,我们把它们带进来,速度等于经过的距离,也即是lambda除以,所花的时间,通常它的单位,是米每秒或者纳米每秒。
