二、TEXT
(1) the purpose of the pneumatic sysytem is to supply compressed air for a
controlled temperature and pressure environment during all phases of
flight and ground operation .air is obtained from engine bleeds. APU、or
from an extermal ground cart through a connector located on the fuselage.
增压系统的作用是为飞行及地面所有阶段的温度和压力控制提供压
缩空气。压缩空气的来源可以是发动机引气、APU、或通过机身上的
连接头与地面气源车相连供气。
(2) The pneumatic system controls the temperature and the pressure of engine
bleed air source. The pneumatic system provides high temperature, high
pressure air for the air conditioning .pressurization, wing and cowl
thermal anti-icing .also, the pneumatic system provides pressure for the
potable water system, hydraulic system and engine starters. The engine
bleed air systems are located on the engine and within the support strut.
增压引气控制发动机引气的温度和压力。增压系统为空调、增压系统、
机翼及整流罩热防冰系统提供高温、高压引气。同时，增压系统还给
饮用水系统、液压系统和发动机起动系统提供压力。发动机引气系统
位于支架内部发动机上。
(3) The normal cabin air source is obtained from the 5th-stage of the engines
at low –engine power, 9th-stage air automatically substitutes to meet user
system needs.
正常情况下，客舱空气来自于发动机低能量的第5 级，9 级空气自动
分配以满足用户系统的需要。
(4) On the top of figure 2-1, the isolation valve separates the left and right
halves of the system. On the left side of the isolation valve, the APU bleed
air duct joins the left side crossover duct; on the right side ,the pneumatic
ground service connector joins the right side crossover duct. From these
ducts the user system are supplied with pressurized air ,governed by the
appropriate control valves.
在图2-1 的上方，隔离活门将左右系统分隔成独立的两部分。在隔离
活门的左边，APU 引气管道立连接着左交输管道；在右边，压缩空
气地面接头连接右交输管道。用户系统可以从这些管道获得压缩空
气，通过适当的控制活门进行控制。

(1) the air conditioning system provides a conditioned air environment for the
passengers 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。
(2) Air is bled from the pneumatic manifold and conditioned by 2 separate
and 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
