查询词典 O2

We examined the metabolic change in responses to anoxia in American cockroach, Periplaneta Americana by measuring the O2 consumption, CO2 production and respiratory quotient.

本研究测量美洲蟑螂的氧气消耗量、二氧化碳排出量与呼吸商，以探讨缺氧对其代谢的影响，连续在氮中缺氧超过38小时的蟑螂，除活动力下降外，行为上无明显的变化。

The isolated a subunit binds oxygen, but the O2 saturation curve is hyperbolic rather than sigmoid.

分离的a-亚基能与氧结合，但氧饱和曲线为双区线而不是S型。

Saturation increases. Curve moves to left. HbO2 can

T下降－－Hb与O2亲和力上升，氧饱和度上升，曲线

Saturation descents. Curve moves to right.

T增加－－ Hb对O2亲和力下降，氧饱和度下降，曲线

An N-channel VDMOS I - V curve is measured after X-ray radiation under condition of different power dissipation. It is found that the property of new interface traps induced by X-ray radiation of self-annealing VDMOS sample does not conform to existing theory reasonably well.

利用X射线对一种N沟VDMOS在不同的负载功率下进行了辐射试验，采用电流-电压测试方法发现这种H2-O2氧化栅介质VDMOS样品存在自退火效应时，新增界面陷阱特性与通常的理论不能够很好地一致。

The effect of magnesium on protecting cells from oxidative stress was probably related to its action on heat shock gene expression.

本研究以人脐静脉内皮细胞为研究对象，观察Mg2 +对H2 O2 诱导的热休克基因表达的影响，旨在揭示镁对内皮细胞过氧化损伤的保护作

The structure features and problems of discharge singlet oxygen generators are introduced.

传统的单重氧产生主要是通过化学的方法：Cl2+H2O2+2MOH→O2(1Δ)+2H2O+2MCl其中M为K，Na，Li。

To detect effects on apoptosis of cortex neuron in DHCA rats, the rat model of occluding bilateral common carotid artery in the deep hypothermic (21C) rats had been established, and flow cytometry, TUNEL, electron microscope, immunohistochemistry and RT-PCR had been studied.: part I: To establish a new rat model of cerebral ischemia/protect during DHCA: 20 SD rats were used in the experiment, little animal respirator was to assist anesthetized rat's respiration after tracheal cannula, artery press through artery spile in femoral artery, electrocardiograph, temperature, blood saturation of O2 (SaO2) and arterial blood gases were monitored during the whole experiment, blood flow of bilateral common carotid artery of rat were occluded about 60 minute when its temperature was reduced to 21 C by ice, then normal temperature was resumed.

本研究采用大鼠深低温颈总动脉阻断模型，应用流式细胞仪、电镜、原位缺口末端标记法、免疫组化法和RT-PCR技术分别检测深低温脑缺血对皮层神经细胞调亡的影响方法：第一部分深低温停循环脑保护大鼠模型的建立：SD大鼠20只，麻醉后气管插管辅助呼吸，用冰块将大鼠的体温降至(21±1)℃，阻断双侧颈总动脉，记录体温、心率、血压、血氧饱和度和血气分析，60分钟后恢复颈总动脉血流，用Longa等的5级评分标准评定4小时和24小时后大鼠神经系统损伤情况。

According to the opening or closing spiracle , a typical discontinuous gas exchange cycle has three distinct phases: the closed period with little or no external gas exchange, the flutter period during which oxygen enters tracheae and little CO (2) escapes and the open period during which lots of CO (2) escape.

根据气门开闭，一个典型的不连续气体交换循环(discontinuousgas exchange cycle， DGC)可以明显分为3个阶段：关闭阶段，极少或没有气体交换；颤动阶段，气门迅速微开和关闭， O2进入气管，少量CO2释放；最后是开放阶段，大量的CO2释放。

For spontaneous ROS generation, DAB 2.0 did not consistently generate hydrogen peroxide production with increasing dosages over the entire culture period while it was capable of generating superoxide content except during the 12 h of incubation.

结果显示ROS的变化，DAB 2.0 并没有在随著时间与剂量增加的培养周期中，使H2O2产生一致的改变；另外，DAB 2.0 使细胞在培养周期中产生的O2-除了十二小时外，其余则是趋於上升的变化。
