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。
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.
巨磁电阻的产生是因为每一个电子带有一个特定方向的自旋。
GMR arises because each electron carries a spin that points in a specific direction.
我们把碳纳米管放在磁性电极之间。然后我们发现被碳纳米管捕捉的单电子自旋方向可以被电势直接控制。
We have placed the nanotubes between magnetic electrodes and we have shown that the direction of a single electron spin caught on the nanotube can be controlled directly by an electric potential.
一个磁化的铁层的电子散射的可能性就取决于是否自旋是否指向与铁磁化的同一方向。
The likelihood of an electron scattering in a magnetized iron layer depends on whether the spin points in the same direction as the iron magnetization or in the opposite direction.
LCVR控制入射光子的偏振度，从而实现对自旋极化电子束极化方向的调制。
The production of spin-polarized electrons and the modulation of polarization direction with liquid crystal variable retarder (LCVR) are discussed.
纵向极化电子，就是自旋和动量方向相同的电子。
Longitudinally polarized electrons are the electrons with spin and momentum pointing in the same direction.
