spin-up

常见例句

I put in the first one spin-up.
首先放入一个自旋向上的。
Likewise with 2s, spin-up, spin-down.
s层也是这样，自旋向上，自旋向下。
With the magnetic field turned on, the iron layers both magnetize, say, in the spin-up direction, so all of the spin-down electrons move through the entire sample without scattering.
加上磁场后，两个铁层都被磁化，假如是上方向，那么所有下自旋的电子移动通过整个样本都没有散射。

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。

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.
并且，在任一个浇满了熔银的坩埚中，银原子中的电子一半是向上转,另一半是向下转。

So this one is spin-up plus a half, this is spin-down minus a half.
所以自旋向上是正二分之一，而自旋向下是负二分之一。
