This was important, for getting the spin rate right is a precursor to everything else.

这个很重要，因为获得自旋速率权是一个好的开始。

And so we can use the spin rate, the rotation rate of a star, as a clock to measure its age.

因此，我们可以用星星的自转速度及速率作为衡量它们年龄的计时器。

What's more, current rate of spin is not a terribly good measure without knowing the original spin rate too.

另外，在不知道初始自传速度的情况下，目前的自传速度并不是一个非常要的测算方法。

Astronomers have measured the rate of spin of a supermassive black hole for the first time - and it is big.

The partnership passed 50 before Malinga and Muralitharan began to turn the screw, the seam-spin combination slowing the run-rate before Muralitharan coaxed Porterfield (31) into edging behind with an attempted cut.

The biggest moment of drama came when the Austrian went into a spin as he hurtled towards the ground, turning at a maximum rate of 60 revolutions per minute.
