您要查找的是不是：
- alveolar ventilation rate 肺泡换气率
- The greater the alveolar ventilation, the more CO2 is removed from the body per unit time. In the normal steady state, the brain regulates ventilation to keep the pCO2 at 40millimeters of mercury (mm Hg). 肺泡通气量越大，单位时间内从机体排出的co2就越多。在正常静息状态下，大脑可以调节呼吸使Pco2维持在40mmHg（5.;3kPa）。
- As the venous blood passes through the lungs, the HCO3- and H+ are transformed by the RBC carbonic anhydrite back into CO2, which then diffuses into the alveolus and is exhaled by the mechanisms of alveolar ventilation. 当静脉血流经肺脏时，HCO3-和H+被红细胞中的碳酸酐酶转回成co2，co2再弥散进入肺泡，并经过肺泡通气机制排出体外。
- Provided the method of calculating natural ventilation rate,and validated it with an example.The result shows that the theoretical value inosculates with measurement one. 利用某建筑实测结果对理论计算所得自然通风量进行验证,结果表明理论计算值和实测结果吻合。
- The maximum ventilation rate of the farrowing room should be checked to ensure adequate airflow. Although this may not necessarily cool the sows, fresh air is beneficial in stimulating appetite. 检查产仔圈舍最大通风量确保足够气流。尽管这不能冷却母猪，但新鲜空气对刺激食欲是有益的。
- By using a litter treatment to limit ammonia production, ventilation rates during brooding can be kept to a minimum, reducing heating costs by 30%. 借助垫料处理技术，可有效控制家禽粪便的氨气释放，进而把育雏期间禽舍的通风频率降至最低，可节约30%25的禽舍取暖成本。
- In the winter of severe cold or cold zones, natural ventilation rates of buoyancy driven flow can meet ventilation requirement basically in underground car park. 在严寒或寒冷地区的冬季，热压作用形成的自然通风量较大，基本能满足地下停车库的通风要求。
- At this rate we won't be able to afford a holiday. 照这样下去，我们不会有时间／钱去度假的。
- The results show that CHS-HA PEC possess proper structure (60-120um), water content (90.15%), ventilate rate (83.65%) and biological characteristics. 结果显示;壳聚糖/透明质酸复合皮肤支架具有良好的孔结构(60-120um)、含水量(90.;15%25)、水蒸气透过率(83
- Influence of alveolar ventilation changes on gastric intramucosal pH in neurosurgical patients 不同通气状态对神经外科手术病人胃粘膜pH的影响
- Calculation of natural ventilation rates by tracer gas decay method was proposed, and definition of indoor criterion of carbon monoxide concentration limit and the carbon monoxide emission from cars were discussed. 提出了利用示踪气体法计算地下停车库的自然通风量，并论述了如何确定室内一氧化碳允许标准及小汽车的一氧化碳排放量。
- At the same time, the analysis of energy consumption is carried out with CI control compared with the conventional temperature and relative humidity control and CO2-based DCV compared with the target per-person ventilation rates. 最后，把CI控制与传统温(湿)度控制方法进行比较，把CO_2需求控制通风与人均新风量标准通风进行比较，对系统节能性进行了分析。
- From the equation of mass balance of tracer gas, the ventilation rates of the cabin(multi room) can be solved by using sigle tracer gas measurement or multi tracer gas measurement. 通过建立示踪气体质量平衡方程式可得到用单种示踪气体和多种示踪气体浓度变化求客舱（多室）通风量和渗风量的方法。
- From the equation of mass balance of tracer gas, the ventilation rates of the cabin(multi-room) can be solved by using sigle tracer gas measurement or multi-tracer gas measurement. 通过建立示踪气体质量平衡方程式可得到用单种示踪气体和多种示踪气体浓度变化求客舱(多室)通风量和渗风量的方法。
- What's the going rate of computer programmers? 计算机程序设计人员的一般工资是多少？
- Determination of ventilation rate in decorating material malls 装饰建材超市通风量的确定
- By power we mean the rate of doing work. 我们说功率就是指做功的速率。
- They charge a fixed rate for each transaction. 他们对办理的每项业务收取一定的费用。
- The going rate for freelance work is 5 an hour. 自由职业者的现行酬金是每小时5英镑。
- This is a room with good ventilation. 这是个通风良好的房间。
