The first item of replication metadata we'll discuss is the Update Sequence Number (USN).
我们要讨论的第一个复制元数据项目是更新序列号(usn)。
If the USN value sent does not match the USN value currently persisted in the repository, the ce server knows that a change was made (by some other caller) since the object was fetched.
如果发送的US n值与储存库中储存的值不匹配，CE服务器就知道已经(由其他调用方)进行了更新，因此该对象已被获取。
If you later fetch or refresh any properties from the server, the current USN is obtained as well.
如果您稍后从服务器获取或刷新任何属性，也会获取当前usn。
