spin down

And that the fact that it split into two was telling them that there must be some new property to the electron, and what we call that now is either being spin up or spin down.

它能一分为二的，事实告诉我们，电子一定有某种新的性质，我们叫它自旋向上或者自旋向下。

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。

The half metallic ferromagnets due to spin up electrons and spin down electrons have different nature around the Fermi level, and have special applications. Then the development and types of half metallic ferromagnets are introduced briefly.

半金属铁磁体因为自旋向上电子和自旋向下的电子在费米能级处不同的性质，具有特殊的应用，在本章中简要介绍了半金属铁磁体的发展和具有半金属性材料的种类。

The tunneling coefficients of electrons with spin up and spin down are different when a magnetic field is applied.

Leap seconds are needed because the earth's spin is slowing down, gradually and unevenly.

润秒之所以必要，是因为地球自转逐渐以不规则的速度减缓。

For convenience we let hopping of spin down electron on this bond adjustable.

为了方便，我们让下自旋电子的跃迁系数是调。

So you can see, if it's spinning on its own axis in this direction we'd call it spin up, where as this way it would be what we call spin down.

你们可以看到，如果它绕自己的轴朝这个方向转，我们就说它是自旋朝上，这个方向我们叫它自旋朝下。

The Earths spin is gradually slowing down, by about two thousandths of a second per day, but atomic clocks are constant.

地球自转逐步减速，以每天2/1000秒的速度，但是原子钟是不变的。
