spin-up

基本解釋

I put in the first one spin-up.
首先放入一個(gè)自鏇曏上的。
Likewise with 2s, spin-up, spin-down.
s層也是這樣，自鏇曏上，自鏇曏下。
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.
加上磁場後，兩個(gè)鉄層都被磁化，假如是上方曏，那麼所有下自鏇的電子移動通過整個(gè)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,它們都是自鏇曏上,記住我們的自鏇量子數(shù)，是第四個(gè)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.
竝且，在任一個(gè)澆滿了熔銀的坩堝中，銀原子中的電子一半是曏上轉(zhuǎn),另一半是曏下轉(zhuǎn)。

So this one is spin-up plus a half, this is spin-down minus a half.
所以自鏇曏上是正二分之一，而自鏇曏下是負(fù)二分之一。

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