抽气

On the basis of previous study, the available procedure for two-dimensional steam flow and heat transfer prediction is modified in the aspects of boundary condition processing method and the matching technique of condenser and air pump performances. The procedure is verified by comparing calculation results of condensers with available experimental data, and a good agreement is achieved.

在前人发展的汽相流动与传热特性二维计算程序基础上，完善了二维计算方法的功能，探讨了各种特殊情况下的边界条件合理给定方法及凝汽器工作性能与抽气器工作性能匹配的方法，并采用制造厂和文献的实验数据验证了物理模型和计算程序的适用性，最后完善了程序的前后处理功能。

The steam pressure from condenser inlet to air extraction outlet gradually declines due to the steam flow resistance in the process.

由于蒸汽在流动过程中存在流动阻力，因此从凝汽器进口到抽气口，蒸汽压力是逐步降低的。

The intensifying high-level anticyclone enhances the pumping effect, which strengthens convergence of air and rainstorm.

3高层反气旋的增强，加强了高空的抽气效应，使辐合上升加强，暴雨增幅。

Common is the vane vacuum pump during use or wear Sun-box rubberand airproof ring aging, plate burning glass not feel free to contact, causing the exhaust is not enough.

众见的是真不满泵的旋片在搁置历程洋不入现磨损或晒框的橡皮稠封圈老化，晒版玻璃不克不及与之稠不分，变成抽气不敷。

Therefore, in the business card printing and membership card making and coater, are you sure you need the IR light plus the cold wind or warm air and exhaust.

因此，在制卡和会员卡制作和涂布机之后，确实需要红外线灯加上冷风或暖风和抽气的支持。

In the reciprocating pump, the suction valve and exhaust valve is a very important component and is vulnerable parts of their work a direct impact on the limit pressure reciprocating pump, extraction rate, power consumption, as well as the reliability of operation.

在往复泵中，吸气阀和排气阀是非常重要的部件且是易损部件，它们工作的好坏直接影响往复泵的极限压力、抽气速率、功率消耗以及运行的可靠性。

Results show that pollutant dispersion of a metal dry etcher during preventive maintenance can be effectively controlled by side venting at a large flow rate near the chamber top whether the chamber is fully open or with the hood. Good agreement between the experimental data and the simulation results is obtained. The SF6 concentration at the breathing zone was also found to be lower than the detection limit of the FTIR spectrometer.

研究结果显示，不论反应腔上方全开或上方有气罩时在反应腔上方进行大量抽气，可有效地控制危害性气体的逸散，模拟的控制效率结果与实验数据相符合，且发现在人员呼吸带的SF6浓度均低於FTIR之侦测下限。

This study is focusing what the variation of cooling coils pipe pitch and deposit direction, which will affect the temperature distribution of the epitaxy produce zone for rotation dick type of MOCVD system, the cooling coils is at the bottom of the reaction chamber. In other, we also consider what the different if they has exhaust device at reaction chamber too.

本研究主要是对转盘式有机金属化学气相磊晶系统反应腔底部冷却管排之管排间距或摆置方位等之变化，对磊晶工件区之温度分布影响；同时，也对冷却管排底下空间中亦做若有抽气时之温度分布差异分析。

Results Abrupt chest pain、soffocative feeling、tachpnea、dry cough and dyspnea were the important symptom in diagnosis of spontaneous pneumothorax.In45cases,5cases are treated by conservative methods.9cases by thoracentesis and31cases by closed tube drainage（15cases operated in mid term）,all patients were cured.

结果 突发性胸痛、胸闷、气促、干咳、呼吸困难等症状是诊断自发性气胸的主要症状依据。45例自发性气胸病人行保守性治疗5例，胸腔穿刺抽气9例，胸腔闭式引流31例（中转手术15例），均治愈出院。

The system consists of cavity coupled ECR microwave plasma source, vacuum system, gas distributing system,d etecting and analysis system and computerized data collecting and controlling system and is provided with a RHEED with differential pumping structure for in-situ real-time monitoring in atom size.

一种宽运行气压范围无离子损伤的ECR微波等离子体增强低温外延系统与技术，系统由腔耦合型ECR微波等离子体源、真空系统、配气系统、检测与分析及计算机数据采集与控制系统组成；配置有带差分抽气结构的RHEED，可实现原子尺度控制生长的原位实时监测。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
