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。)
That reverses the polarity of the atom's magnetic field and ejects it from the trap.(这就会改变原子原来的极性和磁场，原子就会从磁阱中弹出去。)
This would lead to an equal recovery of any fall over time given a polarity reversal.(因此随时间的任何一次下跌都被给予了均等的极性翻转的恢复。)
Electrical cables plugged in the wrong way would switch the "polarity" of a sensor, causing it to confuse left and right.(如果电缆放置错误将改变传感器的“极性(polarity)”，其后果是混淆了左和右。)
Polarity isn't important.(极性并不重要。)
But when you get Home, that good and bad polarity disappears.(但是当你回家的时候，那个有好的和坏的两极消失。)
Several people have asked me about the origins of the polarity concept I began exploring last year.(有几个人曾问我有关极性概念的由来，极性概念是我去年开始研究的。)
At the end of a cycle, the magnetic field rapidly reverses its polarity.(在周期的最后，磁场的两极快速翻转。)
The interpole dimension is the dimensional character of physical polarity.(极间维是物理极性的维度表征。)
