Ease of use: Learning Eclipse takes some spin-up, especially if you would like to investigate all of the tools capabilities.

易用性：eclipse的学习过程有些曲折，尤其是当您想研究所有工具的功能时更是如此。

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 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。

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。

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

ENGADGET: Switched On: The musical mesh for the moneyed

What distinguishes an I-Corps start-up from a typical university spin-out is the way it forces researchers to stop fixating on the technology they have developed.
