membrane polarization 在离子交换膜表面发生水分子解离的一种现象。当向着有离子交换膜隔开的电解质溶液通直流电时，离子即刻作定向迁移。由于离子在膜中的迁移速度比在溶液中快，而溶液中的离子不能迅速补充到膜的界面，从而使膜界面的浓度低于主体溶液，迫使膜界面上的水分子发生解离（H2O→H++OH—），由H+和OH—离子传导电流，这就是常说的膜极化现象。膜极化现象对电渗析过程是不利的，在实际运行中必须避免。

Now, that rapid rise is called depolarization and the membrane is said to be in a depolarized state because it's less polarized or less negatively charged repolarized as negatively charged.
这个迅速上升过程称为去极化,我们称膜处于去极化状态,因为膜的极化程度降低了,或者说是带的负电减少了,而复极化就代表重新带上负电荷
