Principle : to take enous blood in io out of body , and reinfuse to patients ' artery or enous system by artificial heart and lung bypass oxygenation to partly replace heart and lung function 19原理:将体内的静脉血引出体外,经过人工心肺旁路氧合重新注入病人动脉或静脉系统,起到心肺部分替代作用
Biotransforms iron into an organic heme complex and promotes hemoglobin and oxygenation . delivers iron and synergistic vitamins within the infinite complexity of food 利用生化原理使铁质转变成有机血铁复合物,促进形成血色素及氧化。除了含有铁质外,还含有其它矿物质、食物、草本植物,特别是叶绿素,能大大帮助造血。
This article reviews the development on studies of the structure , function and catalytic pathway of nitric oxide synthase ( nos ) . the structure - function relationship and oxygenation mechanism of the inos were discussed 摘要综述了一氧化氮合酶的结构、功能和催化路径,讨论了诱导型一氧化氮合酶的结构和功能的关系以及加氧氧化的机理。
Diffuse optical tomography , an emerging biomedical noninvasive imaging technology , can be used for visualizing and continuously monitoring tissue and blood oxygenation levels that is useful for brain imaging and tumor detection 摘要扩散光层析技术是新近发展的一种生物医学无损成像方法,可用于组织和血氧水平的可视化实时探测,对脑成像和肿瘤监测等具有重要意义。
A . dissolved oxygen in situ treatment ( do - it ? ) is a complicated bioremediation approach that utilizes etec ' s proprietary biological products and oxygenation technology for rapid , consistent biological cleanup of soil and groundwater 答:溶解氧就地处理是一种复杂的生物修复方法。它将本公司专利生物产品和增氧技术相结合,迅速地、稳定地对污染的土壤和地下水进行就地生物清除。
If the history is positie , then it is followed by polysomnography , an oernight sleep study that usually looks at sleep stages , time in stages , oxygenation , co2 leels , time spent in less than 90 % o2 saturation , and rdi 如果规律性研究结果是正性的,那么接下来就要用多导睡眠描记法检查,一种通常观察睡眠分期,各期时间,氧气,二氧化碳水平,饱和90以下氧气的时间,及rdi的通宵睡眠研究。
Quick diathermancy avoid damage to cmos chip and solder . precise design and good technics avoid damage due to attrition . vacuumize avoid alterative because of oxygenation during transportation . antistatic plastic core 传热吸收快,尽可能的避免对芯片和焊盘的损坏;精确的设计和制造工艺避免磨擦对焊盘可能造成的损坏;真空包装避免?品在运输途中氧化变质;防静电塑料芯;符合美国军队及国家宇航局各种标准
The role of extracorporeal circulation : to completely or partly replace cardiac function , to maintain blood pressure and tissue perfusion ; ertro corporeal membrane oxygenation : can completely or partly replace pulmonary function to hae pulmonary resting and restoring 18体外循环功能:替代或部分替代心脏功能,维持血压和组织灌流;膜肺功能:可替代或部分替代肺的功能,给肺一个休息和恢复的时间
The cross - section sem show there is oxygenation layer on the surface of the tin films . the resistances of the films increase with the heat treatment temperature become higher and become bigger with the heat treatment time becoming longer , and decrease subsequently Sem结果显示tin薄膜在未热处理和热处理后表面均比较平整,没有大的晶体颗粒出现; sem断面得出tin薄膜在热处理过程中表面出现氧化层。
Synthesis methods for p - hydroxybenzaldehyde are reviewed and their advantages and disadvantages are briefly compared , to conclude that direct p - cresol oxygenation is a good method , with calm reaction , simple operation , high yield , high purity and little " three wastes " 叙述了对羟基苯甲醛的各种合成方法,并对各种方法的优缺点作了简要对比,认为对甲酚直接催化氧化法反应平稳、操作简单,收率和纯度高,三废量少,是一种很有前途的合成方法。
