spin-up

基本解釋

I put in the first one spin-up.
首先放入一個自旋向上的。
Likewise with 2s, spin-up, spin-down.
s層也是這樣，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.
加上磁場后，兩個鐵層都被磁化，假如是上方向，那么所有下自旋的電子移動通過整個樣本都沒有散射。

So by parallel we mean - they're either both spin up remember that's our spin quantum number, that fourth quantum number.
所以我們意味著,它們都是自旋向上,記住我們的自旋量子數(shù)，是第四個量子數(shù)。

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，在任一個澆滿了熔銀的坩堝中，銀原子中的電子一半是向上轉(zhuǎn),另一半是向下轉(zhuǎn)。

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，而自旋向下是負(fù)二分之一。

Music starts playing instantly, even faster than it would from a local CD that required spin-up time.
