spin up

基本解释

And now I will so when I spin it up, that's right So let me now change the direction.
我会这样当我将它旋转起来,现在改变方向。
So by parallel we mean - they're either both spin up remember that's our spin quantum number, that fourth quantum number.
所以我们意味着,它们都是自旋向上,记住我们的自旋量子数，是第四个量子数。
That way if there are lots of ESBs doing nothing much (e.g. test/dev ESBs) they don't cost anything until they use enough resources to spin up a new VM.
这种方式下，要是有很多ESB并没有进行重负荷工作（如，开发/测试ESB），在它们用到足够的资源需启动一个新VM之前，它们基本没有什么开销。

So by parallel we mean - they're either both spin up remember that's our spin quantum number, that fourth quantum number.
所以我们意味着,它们都是自旋向上,记住我们的自旋量子数，是第四个量子数。

/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。

And, in any arbitrary crucible full of molten silver, half of them are going to be spin-up and half of them are going to be spin-down.
