This structure satisfies the equilibrium condition of carrier density at the contact interface for both holes and electrons.
这种结构使载流子在接触界面两边均能维持其平衡值。

Ion-exchange fibers as a new kind of drug carrier could be used for drug delivery system by the ion exchange equilibrium between drug ions and surrounding counter ions.
离子交换纤维具有“储库”性质和解离平衡特点，可以作为新型的药物载体。
