Asynchronous - If the consumer crashes while waiting for the response after sending the request, when it restarts it can continue waiting for the response, so the response is not lost.
异步——如果使用者在发送了请求之后等待响应时崩溃了，当它重新启动时，可以继续等待响应，所以响应不会丢失。
Synchronous serve and asynchronous receive can be particularly useful in cases where external clients take part in application processing by sending messages to the application.
如果外部客户端通过向应用程序发送消息来参与应用程序处理，同步服务和异步接收将尤为有用。
Message sending is usually asynchronous, although it is easy to build synchronous calls as well and some actor implementations provide those as a feature.
消息的发送通常是异步的，尽管构建同步调用也很简单，而且有些actor实现提供这样的特性。
An invoke via a JMS binding is therefore meant to be asynchronous, because the request is put to a queue and the processing of the reply is triggered by sending a message to another queue.
EJB操作的调用是同步的，JMS绑定的操作是异步的，因为请求被放入一个队列并且回复流程通过发送消息到另一个队列来触发。
Server push is a mechanism of sending the data from server to client in an asynchronous fashion.
服务器推送是一个将数据以异步模式从服务器发送到客户机的机制。
In other words, it USES the synchronous service in an asynchronous way, decoupling the sending of the request from the retrieval of the response.
换句话说，它以异步方式使用同步服务，从而将请求的发送与响应的检索分离开来。
Finally, this paper describes the implementation of the major functions, including the implementation of EJB components, resources object access control and asynchronous message sending.
最后，详细介绍了子系统中主要功能的实现方法，包括EJB组件的实现、资源对象访问控制的实现和异步消息发送的实现等内容。
And it USES asynchronous serial communication technology based on RS-485 electric interface as communication means. The process of sending data frames are analyzed and communication protocol was made.
并且使用了广泛应用的RS- 485电气接口的串行通讯技术作为通讯方式，文中分析了发送数据桢的过程，并制定了通讯协议。
