(1) the air conditioning system provides a conditioned air environment for the
pasngers and crew , heats the cargo compartment, cools the electronic equipment, and supplies air for the pressurization system.
空调系统为旅客和机组提供环境温度的控制，为客舱供热，为电子设备舱降温，还有为增压系统提供空气。

independent cooling packs. Air flow into the packs is regulated by the pack valves.
空气从增压主管道和空调中通过2个隔离的，相互独立的冷却组件中被引入。空气流进组件中通过组件活门调节。
(3) Air from the pneumatic manifold is too warm and must be cooled. The pupo of
2 packs is to reduce engine bleed air temperature to the desired temperature. 从增压主管道中来的空气太热，需要降温。两个组件的作用就是将发动机引气温度降低到需要的温度。
(4) An air cycle machine is an integral unit of each cooling pack. The air cycle
除此之外 machine consists of a turbine wheel and a compressor wheel mounted on a common shaft. Air flowing through the air cycle machine drives the turbine, the
专业英语
turbine drives the compressor ction. As the air leaves the turbine it expands greatly. This expansion can cau the temperature of the air to drop to sub-zero levels.
杨梅的英文 涡轮冷却器是构成每个冷却组件所必需的。它包括一个涡轮和一个压气机，安装在共同的轴上。气流通过涡轮冷却器驱动涡轮，涡轮驱动压气机部分。当空气离开涡轮后急剧膨胀。这种膨胀能够导致空气温度降到零度以下的程度。
(5) In figure 3-1, we can e that the conditioned air from the right pack flows into
the main distribution manifold, the conditioned air from the left pack flows into the main distribution manifold and into the flight compartment. In addition, a trim air line from the left mix chamber adds hot air to the flight compartment duct. The main distribution manifold supplies the pasnger compartment overhead distribution system through tow sidewall rirs.
在图3-1中，我们可以看出，调节空气从右组件流向主分配管道，还有调节空气从左组件流向主分配管道和进入驾驶舱。另外，从左混合舱出来的配平空气管道增加热空气给驾驶舱管道。主分配管道通过两个侧壁竖管供气给客舱顶部分配系统。
(6) A 3-pha fan draws air from the collector shroud through filters and discharges
into the main distribution manifold for redistribution.
lucent 一个三相风扇从收集器防护罩穿过过；滤器和排出口进入主分配管道，用以再分配。

二、TEXT
(1) the fire detection systems monitor airplane components for overheat, fire or
smoke condition. Engine and APU fire and overheat indication occurs on the P8 and P7 panels. Wing and body duct overheat warning occurs on the P5 and P7 panels. Lavatory smoke detection indication is an optional feature that is available. Indication can occur at the lavatory location and or on the P5 panel.
专业英语
火警探测系统监控飞机组件的过热、失火或烟雾等情况。发动机和APU过热和失火指示出现在P8或P7板上。机翼和机身管道过热警告出现在P5或P7板上。厕所烟雾探测指示是一个可选装配件。指示能够出现在厕所位置或P5板上。
(2) Engine fire and overheat detection is provided by detector elements located
你问我答 around the engine. The engine and APU fire detection accessory unit M279, located in the E/E bay determines if a fire or overheat condition exists. When detected indications occur in the flight deck an alarm bell is provided by the aural warning devices unit M315 for a fire condition. The two engine fire extinguisher bottles are located on the upper left aft corner of the main wheel well and are discharged from the flight deck.
发动机失火和过热信号探测由安装在发动机周围的探测元件提供。发动机和APU火警探测组件M279，安装在电子设备舱，用于判断是否有失火或过热情况发生。当在飞机蒙皮探测到火警信号时，音响警告设备M315将给出一个警告铃声。两台发动机灭火瓶安装在主轮舱左下方后角处，并从□□处释放。
(3) The APU detectors n fire conditions only. Monitoring of the nsors is
