对项目相当重要和关键的一段，谢谢各位大神！！！ Therefore, an indirect determination method based on selective solute permeation data has to be used. Recently Kastelan-Kunst et al. proposed a method that enabled the determination of pore size and PSD in the membrane upper layer (skin). The concept and the procedure are based on the surface force-pore flow (SF-PF) model of material transport through a membrane, and experimentally obtained solute rejections for a number of markers. The SF-PF model takes into account interaction forces between the membrane surface and the solute, expressed by an electrostatic or a Lennard–Jones-type potential function, and the solute and solvent transport through the membrane under the influence of such forces. In the course of calculation, pertinent quantities such as permeation volume permeation rate, solute concentration at the pore outlet and solute rejection for a single pore were defined. By adding up these quantities for a collection of pores the permeation rate and the solute rejection factor values of various markers were computed as functions of pore size distribution through the collection of active pores of the membrane’s upper layer. The results were finally compared with experimental data to give the best fit pore size distribution in the membrane’s skin. In addition to pore dimensions and PSD the effective number of pores in the membrane’s skin could have been calculated using this method. |

Therefore, an indirect determination method based on selective solute permeation data has to be used. 因此，必须运用一种基于选择性溶质渗透数据的，间接测定方法。 Recently Kastelan-Kunst et al. proposed a method that enabled the determination of pore size and PSD in the membrane upper layer (skin). 最近Kastelan-Kunst等研究者，提出了一种方法，能确定膜上层（皮肤）中的孔隙大小和PSD(不知道选取什么意思) The concept and the procedure are based on the surface force-pore flow (SF-PF) model of material transport through a membrane, and experimentally obtained solute rejections for a number of markers. 这种概念和程序基于，材料的表面力-孔隙流模型，运输通过膜。并在通过实验获得溶质废料，从而获得大量的标记。 The SF-PF model takes into account interaction forces between the membrane surface and the solute, expressed by an electrostatic or a Lennard–Jones-type potential function, and the solute and solvent transport through the membrane under the influence of such forces. 表面力-孔隙流模型，重视膜表面与溶质间的相互作用力，并通过静电或者Lennard-Jones-类位函数表达出来。同时，在这种作用力的影响下，溶质和溶剂通过运输穿透过膜。 In the course of calculation, pertinent quantities such as permeation volume permeation rate, solute concentration at the pore outlet and solute rejection for a single pore were defined. 在计算过程中，定义了相关的参数，例如渗透量，渗透率，孔排放处溶质浓度，以及单孔溶质废料。 By adding up these quantities for a collection of pores， the permeation rate and the solute rejection factor values of various markers were computed as functions of pore size distribution through the collection of active pores of the membrane’s upper layer. 通过合计这些参数，聚集了许多孔。通过收集膜上层的活性孔，各种标记的渗透率和溶质废料要素价值也被计算出来，作为孔径尺寸分布函数。 The results were finally compared with experimental data to give the best fit pore size distribution in the membrane’s skin. 最终将结果与实验数据对比，从而给出膜皮肤上最匹配的孔径分布值。 In addition to pore dimensions and PSD，the effective number of pores in the membrane’s skin could have been calculated using this method. 除了空尺寸和PSD,膜皮肤上的有效孔数量也可以运用这中方法计算出来。 |
