The practicability and reliability of collagen - chitosan spongy membrane are assessed as a dermal substitute to facilitate the development of tissue engineering skin in future . methods 1 材料和方法一、胶原一壳聚糖多孔膜的制作：以牛健为原料制取二型胶原。
The oxidation curve and sem images show that the oxygen evolution at the interface plays a key role in the transition from the compact al oxide layer to the porous membrane 分孔道的产生说明析氧反应不但在致密膜电解液界面发生，而且在多孔膜孔壁电解液界面也同时发生。
The density of cultivated dermal fibroblast was adjusted to 5x 105 / cm2 , cell suspension was inoculated on glutaraldehyde cross - linked collagen chitosan spongy membrane to make a cell - matrix complex 真皮成纤维细胞在胶原一壳聚糖多孔膜上的培养：将培养的真皮成纤维细胞浓度调整到5x10 ’冰。
The cell - matrix complex was incubated with dmem and 10 % bovine serum under condition of 37 , 5 % co2 - the medium was changed daily . ( 3 ) cell - matrix complex paraffin section was made after 7 days incubation 将细胞悬液接种于戊二醛交联的胶原一壳聚糖多孔膜，加dmem 10小牛血清培养基后放置37 ’ c ， 5 co 。

Investigation of tissue compatibility of collagen - chitosan spongy membrane . ( 1 ) subcutaneous embedding of collagen - chitosan spongy membrane on rabbit . twelve healthy rabbits were divided into four groups randomly 胶原一壳聚糖多孔膜的动物皮下埋植实验：以健康家兔12只作为实验动物，随机分成4组，每组3只。
The obtained qcm sensor has sensitive response to the liquid density and can be expected as a density meter . composite films of p - cyclodextrin ( p - cd ) bound to the titanium dioxide nanoparticles were tightly coated on the surface of qcm 研究发现在干燥失水的过程中，滴加到tio2多孔膜表面的-环糊精分子与纳米二氧化钛发生缩水反应，形成网状物质，牢固地结合在压电晶体表面。
There are three types of collagen - chitosan membrane : non cross - linked type , dry heat cross - linked type and glutaraldehyde cross - linked type . each type of membrane was embedded subcutaneously on dorsal surface of rabbit ear . four of each type were implanted in every group 将： a 、未交联型； b 、干热交联型； c 、戊二醛交联型三种胶原一壳聚糖多孔膜于各组内交叉埋植入兔耳背皮下，每个兔耳背埋植2处，即每种多孔膜于各组内分别埋植4处。
We use collagen and chitosan to make spongy membrane as a dermal substitute in order to develop tissue engineering skin . it is very necessary to investigate the biocompatibility and biodegradation of the couagen - chitosan spongy membrane as an assessment of safety and standardization of a tissue engineering medical product 我们采用胶原和壳聚糖制成的多孔膜作为真皮支架来研制组织工程化皮肤，对胶原一壳聚糖多孔膜进行生物相容性研究和降解研究十分必要，这也是组织工程化产品安全性评价和标准化的需要。
Membrane distillation is an important branch of membrane separation technology which employees a hydrophobic microporous membrane for the separation process . during md process , feed contacts with one side of membrane , after water evaporates on hot side , vapor transfers to cold side under pressure drive , where vapor is condensed on cooling wall and then collected or removed 膜蒸馏技术是膜分离技术中的一个重要分支，它是指利用一疏水性的多孔膜，膜热侧与待处理液直接接触，待处理溶液中的水在膜热侧汽化后，气体在压强差的推动下，通过膜孔传递到膜冷侧，冷凝后收集或除去的一种分离技术。
