You are spin down its winds.

你是旋降它的风。

"If black holes grow by merging, by combinations of black holes, they should spin down quite quickly," Blandford explains.

如果黑洞是依靠合并来成长的，在合并的过程中，他们的旋转速度很快就会变慢。

So you can see, if it's spinning on its own axis in this direction we'd call it spin up, where as this way it would be what we call spin down.

你们可以看到，如果它绕自己的轴朝这个方向转，我们就说它是自旋朝上，这个方向我们叫它自旋朝下。

/2 You can have it equal to plus 1/2, and that's what we call spin up, 1/2 or you can have it equal to minus 1/2, which is what we call spin down.

它可能会等于，我们叫它自选朝上，或者它等于负，我们叫它自旋朝下。

So what that means is that we're limited in any atom to having two electrons per orbital, right, because for any orbital we can either have a spin up electron, a spin down electron, or both.

这意味着在一个原子内,每个轨道上可以有两个电子，对吧，因为对任何轨道,我们可以有自旋向上或者自选向下或者两者都有。

And some of them might be spinning clockwise, in which case, according to the right-hand rule we would consider them spin-down.

而另一些电子则是在顺时针自旋，在这种情况下，根据右手定理,我们会以为它是在向下转。

Still, Motorola boxes currently lack spin down, although a spokesman says that could change next quarter.

Electrons are subatomic spinning tops: Spin up and spin down are the electron's version of clockwise and counterclockwise.

Another would be to slow a pulsar's spin down in pretty short order.
