The nanofiltration membrane pores were modeled as slitlike pores characterized by the fixed pore size, pure water permeability and surface electrical potential.

假定纳滤膜具有狭缝状孔，使用纯水透过系数、膜孔径及膜表面电势来表征纳滤膜的分离特征，用流体力学半径和无限稀释扩散系数表征了离子特性。

In previous studies, only spherulitic structures of PVDF membranes prepared by PVDF/single diluent systems via solid-liquid phase separation were obtained. The PVDF membranes with spherulitic structures always present poor mechanical properties, dense skin layers and wide pore size distribution.

在以往的研究中，PVDF微孔膜大多数选用的是单一稀释剂，通过发生固—液相分离制备的，所得到的膜结构都是球晶状结构，具备这种结构的膜往往存在膜的力学强度差、皮层致密和孔径分布宽等缺点。

In contrast, splanchnic capillaries have a pore size 50–100 times less than that of hepatic sinusoids.

相反，内脏毛细血管孔径较肝窦的小50-100倍。

The strain selection of Pleurotus ostreatus cultivated in maize staw medium was also researched.

在玉米秸栽培灰平菇的试验中，对玉米秸的粉碎粒度，发酵处理方法以及适合玉米秸栽培的灰平菇品种的筛选都做了系统研究，结果表明，以孔径 1 5mm筛子粉碎料的效果最佳；发酵料料水比为 1 ：1 。

However,for the catalytic pyrolysis of sterically hindered PP,the effect of mesoporous molecular sieve sructure on pyrolysis results of PP is more important than that of mesoporous molecular sieve acidity.

而对于具有较大空间位阻的PP的催化裂解反应，催化剂酸性在一定范围内对PP的裂解结果影响不明显，表明催化剂孔结构的作用更重要，较大的孔径有利于PP的催化裂解。

Light quality affected the stomatic characteristics in ginger leaves. The upper cuticle stomatic density, stomatic width and stomatal aperture width under green film was the highest than those of others.

生姜生长的光质环境显著影响了气孔形态特征，绿膜覆盖生姜叶片上表皮气孔密度、气孔宽度、气孔孔径宽度较其他处理大。

A new lower-resolution subzonal wave-front corrector can be approximated by subdividing the wave-front corrector′s aperture into multiple subzones, all actuators associated with each subzone being treated as a whole controlling element.

将波前校正器光学孔径分成多块子区域，每块子区域对应着的所有驱动器作为一个整体控制单元，从形式上可以得到一个空间分辨率较低的分区域波前校正器。

In this thesis, the concentration of graphite powder in the liquid nickel sulfamate and current density are chosen as parameters for composite electrodeposition of nickel and graphite powder. In addition, after electrodepositing, the graphite powder is oxidized into carbon dioxide through heating process for obtaining porous structure. Filter devices of various specifications can be made by controlling the hole dimension of the porous structure.

本研究为了制作出多孔洞结构，将在氨基磺酸镍电铸液中以不同的石墨粉浓度及电流密度为参数进行复合电铸，并且经由加热处理使石墨氧化成为二氧化碳以制造出多孔结构，根据这些多孔结构的孔径大小可以获得各种规格的过滤结构元件。

Then the carbonized material is activated by heating it in the presence of air, CO2, or steam to burn off any tars it has and to increase its pore size.

然后炭化材料激活加热后的空气、二氧化碳、或蒸汽燃烧掉任何tars已经和增加其孔径。

In this paper, the linear relationships were predicted theoretically that tensile strength, tensibility and re-spring degree are affected by the cell size distribution character.

本研究从理论上预测了泡孔孔径分布形态对发泡体的抗拉强度、断裂伸长率、及回弹率之间的内在关系。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
