第三个事实是我们需要记住在，每个轨道加入第二个电子之前，自旋保持平行。

And the third fact that we need to keep in mind is that spins remain parallel prior to adding a second electron in any of the orbitals.

结果表明：零偏压下，电子在反平行等强磁垒结构中输运不会产生自旋极化；

The results show that: (i) the spin-polarization of electron can not be produced in the anti-parallel magnetic barriers structure at zero bias voltage;

当磁矩反平行排列时，自旋对电子输运性质的影响消失，但电子整体的透射概率明显减小。

When the magnetic moments are antiparallel, the spin affect on the electron is vanished, and the conductance decrease obviously.
