| 1. | Transport of a specimen mixture through membrane pores may lead to the complete separation of analyte from other interfering substances provided a suitable antigen ? antibody reaction system is employed 样本混合物通过膜孔的传输使得分析物从其他干扰物中完全分离,因此提供了合适的抗原抗体反应。 |
| 2. | Finally , by studying the heat transfer coefficient and the mechanism of mass transfer through the membrane pores , a complete mathematical model was proposed for the removal of voc from dilute aqueous solutions by vmd 根据对传热系数和膜孔内传质机理的研究,最后得到了真空膜蒸馏脱除水溶液中voc全过程的数学模型。 |
| 3. | Another question discussed was the pore shape correction . the equivalent pore radius of the elongated microcrack membrane pore was corrected by the correlation present in the study on the stomata diffusion of monocotyledons 这合理地解释了在膜接触器气液分离过程中,气液接触面积等于整个中空纤维膜的表面积而不是孔面积这一实验现象。 |

| 5. | Concentrations , bore flow rate , dope solution temperature , coagulant bath temperature , 5 types of composite pu hollow fiber membranes were prepared . the recovery extent of different composition hollow fiber membrane pore size is different . the ability to recover of type 另外,在pu纺丝液中混入适量醋酸纤维素( ca ) ,也可有效改善pu溶液的可纺性,提高pu中空纤维膜的支撑强度和耐压强度,但压力响应性有所减弱。 |
| 6. | In the chromatographic assays , the factors adjusted can also accelerate the transfer rate of the migrating components through the membrane pores , the surface of which is usually coated with an inert protein ( e . g . , bovine serum albumin and casein ) to minimize undesirable nonspecific binding 在免疫层析检测中,调整过的因素可能还会提高流动组分通过膜孔的流动速度,在膜孔的表面一般都铺有惰性蛋白(如牛血清蛋白和酪蛋白)用来减少不想要的非特异性结合。 |
| 7. | Nanofiltration ( nf ) ? nanofiltration is a membrane process capable of separating preferentially different fluids or ions . its membrane ' s pores are typically much larger than the membrane pores used in ro while smaller than in uf . thus , particles with larger charges are more likely to be rejected and smaller molecular weight organics are permeable 纳滤?纳滤是介于超滤和反渗透之间的膜分离技术,具有纳米级的孔径确保它能截留透过超滤膜的那部分相对小的分子量的有机物,而透析被反渗透所截留的无机盐。 |
| 8. | This is due to three reasons : ( 1 ) sio2 influenced the phase behavior of suspensions , shifted the bimodal to lower nonsolvltil concentrations , so that it changed the skin characteristics and pore structure . ( 2 ) there was a kind of interfaeial micro - void ( this is the spaces between the phase of polymer matrix and distributive sio2 particles or ca phase ) existing in the membrane . this enhanced interconnectivity of the membrane pores 原因在于: sio _ 2影响铸膜液的分相条件,继而影响膜的表皮成孔性和膜孔结构; sio _ 2在膜基质中的存在,使平板膜变为多相结构,相与相之间的界面空隙形成了界面微孔,增加了膜孔的连通性: sio _ 2表面有许多si - oh基团,增加了膜的亲水性。 |
| 9. | This is to say , pu composite hollow fiber membranes pore size can become large with transmembrane pressure increasing , and can recover completely with transmembrane pressure reverting to original pressure at a specification condition . from the hagen - poiseuille equal ion , pu composite hollow fiber membrane pore radius magnification was calculated . in our experiment , the variation of membrane pore radius attained to much six times larger than the primitive membrane pore radius 根据一般非变形膜的纯水通量一压力差的直线关系,首次提出了孔径变化分离膜的纯水通量一压力差的曲线关系,并根据hagenf公式,理论上计算出了几种pu复合中空纤维膜最大变形时的膜孔径为原始膜孔径的倍数,最小膜孔径变化也达到原始孔径的一倍多,最大膜孔径变化达到原始孔径的六倍多。 |
