With this approach, the application may receive a duplicate message after a broken connection, but it will not lose any.
使用此方法，应用程序可以在断开连接后接收重复的消息，而不会丢失任何内容。
Likewise, the receiving side must not only agree to send back an ack once they receive a message, but they must ignore any duplicate messages.
同样，接收方不仅要同意一旦收到消息，立刻返回一个ack，还必须忽略任何重复的消息。
For example, if a duplicate source table row matches exactly with the same target table row that has been updated, you will see the error message.
例如，如果复制已被更新的、与相同目标表行匹配的源表行，那么您将会看到错误消息。
A logging client sends a logging message to a web service. The web service receives the logging message, performs duplicate elimination if necessary, and processes the message.
一个日志客户端发送一条日志消息给Web服务，Web服务接收到日志消息后，如果有必要的话除去重复的消息，然后对消息进行处理。
You could just append the log message to the correct text file, but you would have to duplicate the log information style.
您可以只是将日志消息附加到恰当的文本文件，但是您必须得套用日志信息格式。
Any good cryptographic hashing algorithm should make finding a duplicate hash for an alternative plaintext difficult, even given a known message and its associated message hash.
任何好的密码杂凑演算法应该是这样的，即使给定一个已知的讯息和与它关联的讯息杂凑，也很难找到替代明码的迭代杂凑。
