辅助DNS服务器直接从主dNS服务器传输其区域信息，并在本地保留副本。
Secondary DNS servers transfer their zone information directly from the primary DNS server and keep a copy locally.
结果是服务器、本地副本各自保留自己的编辑，而二者都没有意识到它们已经不同步。
The result is that the server retains its own edits, and the local copy retains its own edits, and neither realizes that they are out of synch.
