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。
So one goes spin-up and the other goes spin-down.
所以一个是自旋向上,另一个是自旋向下。
I put in the first one spin-up.
首先放入一个自旋向上的。
