Water content test revealed that grafting amps on pvdf membrane was an effective method to improve the hydrophilicity of pvdf membrane 实验表明，在pvdf中空纤维膜表面接枝amps可有效提高pvdf中空纤维膜的亲水性。
This paper introduces the main complications of hollow fiber membrane , and describes the actuality of fgd by hollow fiber membrane contactors 摘要本文介绍了中空纤维膜的基本情况，概述了中空纤维膜烟气脱硫技术的研究现状，并对其发展前景进行了展望。
The surface compositions of the pretreated pvdf membrane were determined by fourier transform adsorption spectrum ( ftir ) and x - ray photoelectron spectroscopy ( xps ) 采用傅立叶红外光谱( ftir )和x光电子能谱( xps )对预处理前后pvdf中空纤维膜表面化学结构进行分析。
[ methods ] two phage - epitope libraries were screened with two anti - vegf neutralizing monoclonal antibodies - jh121 and vg189 , the clones were tested by dot blotting and elisa 并通过硝酸纤维膜斑点印迹法进行阳性克隆鉴定。 elisa分析阳性噬菌体克隆与抗体的亲和力。
In order to avoid pollution , we choose polyethylene as the raw material , through heating it in the high temperature and physic extension measure , we get the hollow fiber membrane 中空纤维膜表面分布着0 . 01微米- 0 . 1微米不等的孔径，这些孔径可以去除以往单一的活性炭净水器所不能去除的细菌、铁锈等杂质。
In this paper , we adopt a simple chemical modification method for the surface functionalization and grafting of polar monomers onto pvdf membranes , which provides excellent hydrophilicity to the polymeric surfaces 本文采用化学接枝改性的方法对pvdf中空纤维膜进行亲水改性，研究了预处理条件对接枝反应的影响，以及改性后膜性能的变化。
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。
Sio2 play an important role to pressure - rvsponsi vity of pe composite hollow fiber membranes . oil - water emulsion was treated using as - spun pu composite ho ] low fiber membranes . the flux decline was very severe compared wi th pure wate 可见，实验所纺的两种中空纤维膜可以应用于油水分离领域，并且当膜污染进行反洗时，膜孔径变大，而工作时膜孔径回复较好。
Constructed of plush fabric , with a lining of dupont hytrel , this jacket is wind - resistant , water - proof and breathable and light yet warm enough to wear at winter activities . thoughtfully designed to allow sports - lovers to stay warm and dry in winter 特别采用超细刷毛布做贴合处理，夹层采用美国杜邦纤维膜dupont hytrel ，既可挡寒风又具有排湿透气功能，冬日活动时轻便保暖又不易湿透。
In this paper , exhaustive studies on the mechanism of draw - interfacial phase separate micro - void , pan / pu blending system , melt spinning technology of pan / pu hollow fiber membrane , and the structure - property of pan / pu hollow fiber membrane were fulfilled 本文对拉伸相界面分离成孔机理， pan pu共混体系， pan pu中空纤维膜的熔融纺丝-拉伸致孔工艺及pan pu共混膜的结构和性能作了研究和探讨。
