抽出空气

Even with the air pumped out the bulb, the tungsten filament slowly vaporize s.

即使灯泡中的空气被抽出，钨丝也会慢慢地蒸发。

Application of a few drops of Fixative No.1(2% glutaraldehyde in 0.1M cacodylate buffer at pH7.2) to the tissue before cutting into slices can prevent sticking and drying and initiate the fixing process. The air in the plant tissues prevent the resin to reach the organelles, which makes the fixation difficult.

由于植物组织中都含有一定的空气，致使树脂不能顺利浸润细胞器，这就给材料包埋带来困难，这可以通过在预包埋过程中处以真空处理以抽出植物组织中的空气，以便更好包埋。

Air sparging is widely used for remediating groundwater contamination of solvents or gasoline fuels. Air is injected into the saturated zone in the plume area through sparging well. Injected air contacts the contaminated groundwater and removes volatile organic compounds by volatization.

气提法应用在地下水及土壤污染整治的原理是将空气由注气井打入受污染区域的饱和含水层，注入地下水层的空气与非水相的挥发性有机污染物接触，会将污染地下水层的挥发性有机物挥发出来，并往上流入非饱和层中，再由抽气井抽出非饱和层之气体，将污染的挥发性有机物回收到地表进行处理。

Generally, the air leakage in condenser can be attributed to tube and valve imprecision of vacuum system or deficiency or even intermittence of steam seal pressure. Besides, it is probably engendered by low-efficient air ejector, which cannot totally extract the air leakage in condenser.

空气漏入凝汽器的原因，通常是由于真空系统管道阀门不严密或汽封压力不足甚至中断所造成的；也可能由于抽气器效率降低，不能将漏入凝汽器的空气完全抽出而造成的。

The function of air ejector: The air in the shell must be extracted by air ejector since the commencement of condenser due to the vacuum condition for condenser. During the operation of condenser, the air carried by exhaust steam of steam turbine and the air leaked from imperfect vacuum system must be continuously extracted so as to maintain the condenser vacuum.

抽气器的作用：由于凝汽器处于真空条件下工作，所以在凝汽器开始运行时，必须要用抽气器将其壳体内的空气抽出以建立真空；并在凝汽器运行过程中，将汽轮机排汽中夹带的空气和从真空系统不严密处漏入的空气不断抽出，以维持凝汽器的真空。

The air is evacuated from the furnace.

从真空炉中抽出空气。

Is not the Heat of the warm Room convey'd through the Vacuum by the Vibrations of a much subtiler Medium than Air, which after the Air was drawn out remained in the Vacuum?

是不是热了温暖的房间convey'd通过真空振远subtiler中等比空气，经空气抽出保持在真空状态？

Large air separation plant 40000m3/h, This plant adopts molecular sieve system to adsorb CO2, C2H2, moisture and CnHm in air to pre-purify air, by use of air booster compressor, to pressurize some of purified feed air by two sections, pressurized air to warm up high pressure liquid oxygen in high pressure coil heat exchanger to ambient temperature and delivere out off cold box to coal gasification, some pressurizrd air by first section is drawn from middle part of coil heat exchanger and expanded in medium pressure expander then led into lower column, other part of pressurized air by second section is drawn from cold end of coil heat exchanger and led into lower column after throttling, un-pressurized feed air is cooled by return gas in plate fin heat exchanger and led into lower column.

产品描述：采用常温分子筛空气预净化系统吸附空气中的CO2、C2H2、水份和一些碳氢化合物，使用单独的空气增压压缩机将部分净化后的原料空气分为两段增压，增压后的空气在高压绕管式换热器中将经液氧泵加压的高压液氧汽化并复热至常温送出冷箱直接供煤气化工序使用，第一段增压后的空气，部分从绕管式换热器中部抽出经电机制动的中压透平膨胀机膨胀后送入下塔，另一部分经第二段增压后从绕管换热器的冷端抽出节流后送入下塔，未经增压的原料空气在板翅式换热器中被低压返流气体冷却后进入下塔。

Air is transfened into hot air by passing through the heater,and goesinto the hotair separator on the top of he dryer,then goes into the drying room evenly.at the same time liquid materials are sent to the centrifugal atomixer on the top of the dryer the the screw pump with stepless speed regulation,and atomized into timy dr-oplet which will contact hot air,then dried into dry product within shortest time.

空气通过加热器转化为热空气，进入装置在干燥室顶部的热风分配器，然后均匀的进入干燥室，同时通过无级调速的螺杆泵将料液送至装置在干燥室顶部的雾化器，使料液雾化成极小的雾化液滴，料液和热空气并流接触，水份迅速蒸发在极短的时间内干燥为成口若悬河，成品经干燥塔底部和旋风分离器排出，废气由风机抽出排空。

If air is recirculated to production areas, measures shall be taken to control recirculation of dust from production.

在生 产区，空气中发生空气污染，应用排气系统或其他系统充分抽出空气，控制污染。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
