| 5. | The extreme conditions under which the bacteria live bear a resemblance to those of early earth , potentially offering insights into the nature of organisms that lived long before our planet had an oxygen atmosphere 细菌所生存的极端环境与地球早期的环境很相似,潜在提供了洞察那些早在地球形成有氧大气以前就存在的有机体特性的机会。 |
| 6. | Within six hours after an infant is placed in a high - oxygen atmosphere , vasoconstriction of the immature vessels of the retina occurs , which is reversible if the child is immediately returned to air , but irreversible if oxygen - rich therapy is continued 婴儿置于含氧浓度高的空气中6个小时以内,未发育成熟的视网膜血管会发生血管收缩,如果立刻把孩子转移到空气中,这是可逆的,如果富氧治疗继续的话,会变成不可逆的。 |
| 7. | The synthesis , structure , properties and interface behavior of nanocomposite materials based on layered v2o5 and moo3 , which can be topotactically reacted with alkali - metal ions ( li + , na ~ ( + ) , etc . ) have attracted more attention in recent years . the intercalation of polymer into the interlayer is expected to improve the interface and interlayer structure of these materials , resulting in desirable novel characteristics . in this dissertation , vanadium pentoxide sols were synthesized by melt quenching in oxygen atmosphere 近年来,利用能与锂等碱金属离子发生拓扑化学反应的v _ 2o _ 5 、 moo _ 3等层状氧化物的层间结构特征,将聚合物嵌入层间来改善界面和层间性质,使材料呈现出许多优异的性能,对这类材料合成、结构、性能和界面行为的研究引起了人们的极大兴趣。 |
