查询词典 tubular membranes

NaA zeolite membranes have been found a potential application in the separation of the small-sized gas molecules by molecular sieving and dehydration of liquid mixtures by pervaporation. However, there are some problems in the preparation in the NaA zeolite membranes such as the scarce support types, insufficient study on the synthesis rules and few literature concerning the NaA zeolite membranes preparation on the inner surface of the tubular support.

Changes in brain tissue similar to those of newborn in HIE were detected after 2 hours of hypoxia and ischemia.Meanwhile,swelling of kidneys,hemorrhage below encapsules,swellin of tubular epithelial cells,necrosing and falling of a few tubular epithelial cells,and narrowing of tubular lumens were observed.The basement membranes of renal tubules remained normal ...

结果发现新生猪经2小时缺氧缺血后，在脑组织出现类似新生儿HIE病理损害的同时，肾脏出现肿胀，包膜下出血，肾小管上皮细胞肿胀，管腔变窄，少数上皮细胞坏死脱落，肾小管基膜完整，血清尿素氮及肌酐明显升高（P＜0.025及P＜0.05），表明在HIE状态下新生猪已出现肾脏的病理及功能损害，但损害程度较轻，解除缺氧72小时后，上述损害基本恢复正常。
