1·The magnet creates a field that changes the polarity of a tiny, tiny portion of the metal particles which coat each platter's surface.
这个磁体创建一个磁场，能改变覆盖在磁盘表面的小金属粒子的极性。
2·The interpole dimension is the dimensional character of physical polarity.
极间维是物理极性的维度表征。
3·There are impact factor to be discussed such as solvent polarity and nucleofuge.
准备讨论的影响因子包括溶剂极性和离核试剂。
4·But her equipment, too, must be set to one mode or the other, and she cannot be certain that the polarity of the photon she sends to Bob is correct.
同样，她的设备也只能选取一种模式进行发送，由于信息是后验的，她并不能确定其送给“鲍勃”的光子极性是否正确。
5·If a cell does get fully drained, though, it can go into a state known as polarity reversal, in which the surrounding good cells drive the bad one in reverse.
如果电池没有完全耗尽，便会进入一种称为极性颠倒的状态。这种状态下，周围具有电量的电池会反过来推动电量很少的电池工作。
