The constraint of steady-state operation for sieving or ultrafiltration across membranes greatly restricts possible theoretical mechanisms. Effective sieving in the steady state requires the coexistence of a removal mechanism with the rejection mechanism. These points are illustrated without elaborate mathematics by a model of membranes in a series array with intervening compartments. This model also shows that in certain regimes the structure of the first membrane alone determines the overall sieving characteristics of the array.
跨膜筛分或超滤的稳态操作限制极大地制约了可能的理论机制。稳态下的有效筛分要求去除机制与截留机制同时存在。通过带有中间隔室的串联膜阵列模型，无需复杂数学推导即可说明这些要点。该模型还表明，在某些情况下，仅第一个膜的结构就决定了整个阵列的筛分特性。
