Down-Spin 下自旋
Spin Down 旋转减慢 ; 自旋向下 ; 硬盘将自动关闭 ; 盘片降速
spin down timeout 时间 ; 常间
Spin-Down 盘片降速 ; 自旋减慢
spin-down time 消旋时间
spin-down effect 消旋效应
spin-down process 消旋过程
Spin-up or spin-down 旋转加速
She sat down and tried to spin; but the threads cut her tender fingers till the blood ran.
她坐下来,试着纺线;但是这些线割破了她柔嫩的手指,鲜血直流。
Some of them might be spinning clockwise, in which case, according to the right-hand rule we would consider them spin-down.
它们中的一些可能是顺时针旋转的,在这种情况下,根据右手定则,我们认为它们是向下旋转的。
So what that means is that we're limited in any atom to having two electrons per orbital, right, because for any orbital we can either have a spin up electron, a spin down electron, or both.
这意味着在一个原子内,每个轨道上可以有两个电子,对吧,因为对任何轨道,我们可以有自旋向上或者自选向下或者两者都有。
And some of them might be spinning clockwise, in which case, according to the right-hand rule we would consider them spin-down.
而另一些电子则是在顺时针自旋,在这种情况下,根据右手定理,我们会以为它是在向下转。
/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.
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。
