英语翻译
A system is a set of interrelated parts that performs one or more processes to accomplish
specific objectives.Consider a home air-conditioning system.This system has a number
of interrelated parts such as the compressor,the fan,the thermostat,and the duct work.
The most obvious process (or series of actions designed to accomplish an objective) is the
cooling of air; another is the delivery of cooled air to various rooms in the house.The
primary objective of the system is to provide a comfortable,cool environment for people
in the house.Notice that each part of the system is critical for achievement of the overall
objective.For example,if the duct system were missing,the air conditioner would not be
able to cool the house even if the other parts were present and functional.
But how does a system work?A system uses processes to transform inputs into
outputs that satisfy the system’s objectives.Consider the cooling process.This process
requires inputs such as warm air,Freon,and electricity.The inputs are transformed into
cooled air,an output of the cooling process.The output of the process,cooled air,is
obviously critical to achieving the overall objective of the system.
The cooled air and additional electricity become inputs to the delivery process.This process transforms the inputs so that a portion of the total cooled air is delivered to each room of the house (the output is delivered air).In this way,all rooms are cooled to the desired temperature,thereby achieving the system’s objective.

一个系统是一些互相关联的部分组合起来以实现一个或更多流程,达到特定目标的集合.想想一个家庭空调系统.这个系统有许多的互相关联的部分,比如压缩机,风扇,恒温器和导管.最直观的流程（或者一系列设计的以实现一个目标的功能）是让空气凉爽；另外一个是将凉爽的空气输送到房子里的不同房间里去.这个系统最基础的目标是为房子里的人们提供一个舒适的,凉爽的环境.注意系统每一个部分都是达到总体目标的重要的组成.例如,如果管道没有了,尽管其他部分依然存在且可以工作,空调将不能再让房间凉爽.
但是一个系统怎么样才能工作呢?一个系统采用一些流程来将投入变成产出以便达到系统的目标.想一下制冷的流程.这个流程需要一些投入,比如温暖的空气,氟利昂和电力.这些投入被改变为制冷流程的产出,凉爽的空气.冷气作为这个流程的产出,很明显是达到这个系统目标的决定性的因素.
