摘　　要：提出了超滤过程中的粒子迁移模型 ,得到了描述该过程的数学表示式L1 xi+L2 ·xi· p=Li ρg +Ci0 exp - g Mi Hir .应用此模型可以在全部操作范围内很好的解释压力与渗透流率之间的关系 ,其置信度为 0 .9951 .The mass transferred model for whole operate range of the ultrafiltration processes have been developed based on the theory of mass transfer and energy transfer as well as momentum transfer. The mass osmosis equation can be expresfsed as L 1x i+L 2·x i·p=L iρg+C i0 exp -gM i ir.The equation is used to described the ultrafiltration processes of black liquid of grass slurry in whole range perfectly through the stochastic simulated.
