返回节点的操作系统，如“windows”。
Returns the operating system of the node, such as "Windows".

By clicking on a map or a node of a GUI network graph, the network operations center staff could monitor the status of any particular device and change its setting and configurations.
通过将DOM操作限制到沙箱元素的子元素和节点，您可以在沙箱中安全地操作浏览器的DOM。
By restricting DOM manipulation to child elements and nodes of the sandboxed element, you can securely manipulate the browser's DOM within the sandbox.
某些管理操作需要其包含的节点都是兼容的并且属于同样的节点组。
Certain administrative operations require that the nodes involved are all compatible and belong to the same node group.
回想一下，当指定了初始上下文后，稍后将在该初始上下文节点的子节点内进行所有的搜索操作。
Recall that once the initial context has been specified, all later search operations take place within the child nodes of that initial context node.
从概念上来说，关系数据行(元组)按照自下向上的方式流过查询计划中的操作节点。
Conceptually, rows of relational data (tuples) flow through the operation nodes in the query plan from bottom to top.
对于异步复制，顺序是一样的，但是无需等待目标节点确认已经收到写入操作，就可以完成生产节点上的写入操作。
With asynchronous replication, order is preserved, but the write is allowed to complete without waiting for an acknowledgement from the target node that the write has been received there.
而且，对会话的每次变化都会形成对每个节点的操作，因为节点必须处理进来的消息更新，让会话的备份拷贝与变化一致。
Furthermore, every change to any session also creates work for every node, because it has to process an incoming update message and make its backup copy of the session consistent with the changes.
每一个节点上显示的数字都是优化器对基础数据源或操作节点的基数的估计。
The number shown in each node is the optimizer's estimate for the cardinality of the underlying data source or operation node.
对于同步复制，目标节点不接收到此写入操作，生产节点上的写入操作就无法完成，这样可以保证两边的复制一致。
With synchronous replication, the write on the production node does not complete until it has been received on the target node, so you are guaranteed identical copies on each side.
实际上，您可以将按照类型查找子节点的操作视为可封装在访问者自身中的访问者操作。
In fact, you can think of finding children on a per-type basis as a visitor operation that can be encapsulated in a visitor itself.

When the node agent is unavailable, administrators are unable to invoke any operations for that node.
可能需要规范化这个新元素的文本节点以简化后续操作。
Optionally, normalize the text nodes of this new element, to make sure things are easier later on.
故障恢复/回退：这是在故障转移发生后将资源组移回其最初在其上运行的原始节点的操作。
Failback/fallback: This is the action of moving back resource groups to the nodes on which they were originally running after a failover has occurred.
在找到节点之后，标记将对该节点执行特定的操作。
Once the node is found, the tag performs its specific action against that node.
另一项常用的操作是将节点的值设置为希望的值，如清单3所示。
Another common action is to set the value of a node to a desired value, as shown in Listing 3.
相反，活动的参数节点(必须同其规范操作的参数相一致)根据需要被直接引用到输入和输出插口上。
Instead, the parameters of the activity (which must correspond to the parameters of its specification operation) are referenced directly on input and output pins where needed.
