申武投资初期安装了一个热交换器，将进入炉内的空气预热，降低了客户的燃料成本。
Shenwu puts up the initial investment to install a heat exchanger that preheats the air going into the furnace, slashing the client's fuel costs.
下列交换器类型都在规范中被提及。
The following exchange types are mentioned in the specification.
接受和发送消息：交换器类型。
交换器的类型。
这些交换器的命名规则是amq.前缀加上类型名。
These exchanges are named after the their type with a prefix of amq., e.g.
公司主要生产经营船用热交换器和压力容器。
The company production and management of marine heat exchangers and pressure vessels.
持久性：如果启用，交换器将会在协商器重启前都有效。
Durability: if set to true the exchange will survive a broker restart.
水被从地下的热交换器泵出来，将夏天储存的热能带出来。
Water is pumped through the heat exchangers to pick up the heat that was stored during summer.
如果热交换器腐蚀了导致海水进入反应堆怎么办？
What if heat exchangers corrode letting sea water into the reactor?
这组接口的核心就是虚拟文件系统交换器(VFS)。
At the core of that set of interfaces is the virtual file system switch (VFS).
交换器(Exchange)，它是发送消息的实体。
The exchange which is the entity to which messages are sent.
MX(邮件交换器)——负责处理该域的电子邮件的服务器主机名。
MX (mail exchanger) — the hostname of a server responsible for handling E-mail for the domain.
绑定器没有名字，它们的生命期依赖于所紧密连接的交换器和队列。
Bindings have no names and are dependant on the lifecycle of the exchange and queue they tie together.
所有这些组件的属性各不相同，但是只有交换器和队列同样被命名。
All these component have different properties but only the exchange and the queue are named.
在每个区域网路区段中，选定一个最靠近根交换器的的交换器。
Designate one of the switches as the closest one to the root, for each LAN segment.
伊文思还创立了SLIDE——路灯干扰数据交换器，旨在进一步研究这种现象。
To further investigate this phenomenon, Evans founded SLIDE, the Street Lamp Interference Data Exchange.
没有绑定器，哪怕是最简单的消息，交换器也不能将其投递到队列中，只能抛弃它。
Without bindings the exchange would simply never deliver the message to a queue but just drop them.
客户端声明一个它想要发送消息的目的交换器，然后将消息传递给交换器。
The client declares the exchange it wants to send the message to and publishes the message to it.
客户端可以通过交换器的名字来发送消息，也可以通过队列的名字收取信息。
Knowing the name of an exchange grants a client the power to publish messages to it, knowing the name of a queue the capability to receive messages from it.
自动删除：如果启用，那么交换器将会在其绑定的队列都被删除掉之后自动删除掉自身。
Auto deletion: if set to true the exchange will get deleted after all queues bound to it have been deleted.
虽然不能被命名，但是队列也有以下属性，这些属性和交换器所具有的属性类似。
Apart from being named, queues also do carry properties. These are basically the same properties exchanges carry.
在100深的地下含水土层，热水会进入一系列业已敷设好的热交换器去加热地下水。
About 100 metres down lies a natural aquifer into which a series of heat exchangers have been built.
惰性：如果没有声明交换器，那么在执行到使用的时候会导致异常，并不会主动声明。
Passivity: this will not declare the exchange but will cause an exception if no such exchange is present.
不同于队列的是，交换器有相应的类型，表明它们的投递方式(通常是在和绑定器协作的时候)。
In contrast to queues, exchanges have been shown to have a type associated with them that dictates their routing behaviour (usually in collaboration with bindings).
现在有一个课题，关于在保留的amq命名空间中可用的交换器，它能获取协商器所有的日志信息。
Currently there is one topic exchange available in the reserved amq. namespace which gets all the log message of the broker.
系统调用接口的作用就像是交换器，它将系统调用从用户空间发送到内核空间中的适当端点。
The system call interface ACTS as a switch, funneling system calls from user space to the appropriate endpoints in kernel space.
我们的例子中，fanout交换器不会解释任何东西：它只是将消息投递到所有绑定到它的队列中。
As our example already hinted the fanout exchange does not interpret anything at all: it delivers messages to all the queues bound to it.
