Finally, spin relaxation of polarized atom due to spin-exchange collisions and spin-destruction collisions is put forward.

最后，提出了因自旋交换碰撞和自旋销毁碰撞引起的极化原子的自旋弛豫。

The calculated local spin results are comparable to previous ones and the obtained pariwise exchange coupling constants are in well agreement with experiments.

通过计算得到的局域自旋结果和前人的具有可比性，同时所得的磁交换耦合常数和实验值很吻合。

The electromagnetic attraction is pictured as being caused by the exchange of large Numbers of virtual massless particles of spin 1, called photons.

人们将“电磁吸引力”“描绘成”是由于“称作”“光子”的“无质量的”自旋为1的“粒子”的交换所引起的。

The reasons behind the drop were unfavorable foreign exchange and the 20% spin-off of Zoetis.

Joe Cornell, founder of Chicago-based Spin-Off Advisors, says the next step will likely be an exchange offer from Pfizer later this year, giving shareholders the ability to exchange some of their holdings for shares in the animal health business, likely at a discount to incentivize participation.
