I had flown into Dallas for the sole purpose of calling on a client. Time was of the essence and my plan included a quick turnaround trip from and back to the airport.

之前我为了见一个客户飞了一趟达拉斯，时间就是生命，按照行程计划，我马上又折返回到了机场。

youdao

The invoked service runs on its own thread and, when it completes its processing, the response is sent back to the calling client, which is received on a different thread.

调用的服务在自己的线程上运行，该服务完成其处理时，将相应发送回给调用客户端，而调用客户端将使用一个不同的线程来接收这个响应。

For example, as an alternative to calling some GetQuote method on an object instance, the client code might post a GetQuote message to an input queue.

例如，作为对对象实例调用某个GetQuote方法的备选方案，客户机代码可以将GetQuote消息传递到输入队列中。
