OBJECTIVE: To study the effects of prolonged 75% oxygen exposure on the expression of vascular endothelial growth factor and its receptors (VEGFR1 and VEGFR2) in the neonatal rat lungs and to elucidate the effects of prolonged exposure of high concentration of oxygen on lung vascular development and its relationship with bronchopulmonary dysplasia.

目的：研究持续吸入75%氧对新生大鼠肺血管内皮生长因子（vascular endothelial growth factor，VEGF）及其受体（VEGFR1和VEGFR2）表达的影响，探讨较高浓度吸氧对肺血管发育的影响及与支气管肺发育不良（bronchopulmonary dysplasia，BPD）的关系。

TiO2 is known to exist in three distinct structures: two tetragonal phase for anatase and rutile and a third orthornombic phase for brookite. Rutile has the most stable structure and physical and chemical properties. In rutile structure oxygen cavities move quickly so that rutile has better gas sensing respond and become a chief material use for oxygen gas sensors.

其中金红石结构是最为稳定的晶型，不但具有最为稳定的物理、化学性能，而且在金红石结构中，晶格中氧空位的迁移率较高，因而TiO_2金红石结构气敏响应效应较好，从而使金红石结构TiO_2氧化物材料成为氧敏传感器的首选材料之一。

Once the higher the concentration of carboxyhemoglobin, hemoglobin to carry oxygen to the tissues of the function will be hindered, and the impact of the shortage of oxygen supply the most sensitive central nervous system and cardiac function, caused by hypoxia, which lead to poisoning symptoms .

一旦碳氧血红蛋白浓度升高，血红蛋白向机体组织运载氧的功能就会受到阻碍，进而影响对供氧不足最为敏感的中枢神经和心肌功能，造成组织缺氧，从而使人产生中毒症状。

Automobile exhaust the highest level of carbon monoxide, it can enter through the respiratory tract of gestation, the blood was absorbed, combined with hemoglobin to form carboxyhemoglobin, lowering blood oxygen, blood weaken the oxygen supply of human tissues, resulting in tissue hypoxia, which led to headaches and other symptoms, or suffocation.

汽车尾气中一氧化碳的含量最高，它可经呼吸道进入肺泡，被血液吸收，与血红蛋白相结合，形成碳氧血红蛋白，降低血液的载氧能力，削弱血液对人体组织的供氧量，导致组织缺氧，从而引起头痛等症状，重者窒息死亡。

The oxygen is the metals that the water supply main causticity the material boiler of the system and boiler would decay the thermodynamic energy system for aquatic deliquescence oxygen.

氧是给水系统和锅炉的主要腐蚀性物质，锅炉给水中的溶解氧会腐蚀热力系统的金属。

CGA has established the definition of an oxygen-enriched atmosphere as one containing at least 23% oxygen.

CGA将至少含有23%的氧的空气定义为富氧空气。

Because chronic obstructive inflammation of airway severely influences the ventilation and exchange function of COPD patients, The motor ability of patients is limited .Despnoea and fatigue limit patients to sedentary,because of this, skeletal muscle began to analosis,oxygen uptaking capacity of skeletal muscle descends,and concentration of chondriosome degrades.Function limitation of skeletal muscle causes oxygen needs increase,so vicious cycle emerges,and further to restrict patient's respiratory and motor function.

由于气道的慢性炎症性阻塞，严重影响了慢阻肺患者的通气及换气功能，使得患者的运动能力明显受限，因喘息和疲劳而限制了患者的运动能力，使患者出现久坐，由此出现骨骼肌的萎缩，骨骼肌摄氧能力下降，线粒体氧浓度降低，骨骼肌的功能受限又会引起通气量不足，进而引起低氧血症和高碳酸血症，使患者的摄氧需求增加，由此出现恶性循环，进一步制约了患者的呼吸和运动功能。2001年正式提出肺康复作为中重度COPD患者稳定期非药物治疗的首选管理方案。

Therefore this work mimicked this process for the first time by using macrocyclic complex. The quantity of absorbed oxygen and the absorption rate of oxygen were determined.

本文首次用大环配合物对这一过程进行了模拟，并测定了氧化反应中的吸氧量和吸氧速率常数。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
