联合查询的复杂性：为了执行查询，联合服务器需要执行多少筛选、联接、排序之类的子操作。
Complexity of the federated query: how many sub-operations such as filtering, joining, sorting, and so on, does the federation server need to execute to perform the query.
在多库系统中，对全局视图的存取操作要分解为针对多个LDB的子操作，可能还要对数据模式及查询语言进行转换。
In multidatabase, access to global view will be decomposed to several sub-operations to several LDB, and perhaps also need data schema translation and query processing.
要确保该脚本不会在执行所有的远程命令之前退出，您需要添加一个wait命令，以等待该脚本的所有子操作执行结束。
To ensure that the script doesn't exit before all the remote commands have executed, you need to add a wait command to wait for the children of the script to finish.
为了弥补这个缺点，程序员需要将应用程序划分为一组子应用程序，这样操作系统才可以在不同优先级上运行。
To compensate, a programmer would need to partition an application into a set of applications that the operating system can then run at different priorities.
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.
指定初始上下文后，将在该节点的子节点中执行所有的搜索操作(例如查找特定用户)。
Once you specify the initial context, all later search operations (such as locating a particular user) take place within the child nodes of that node.
要使用表子查询，需要使用SQL操作符将嵌入式查询与布尔表达式组合在一起。
To use a table subquery, you need to use an SQL operator to combine the embedded query with a Boolean expression.

In addition, sub-entries for each reporting agent will show Linux operating system statistics.
结果是一个单一元素，然后可以轻松地取出这个元素的display子元素，并用标准的DOM操作在页面上显示它，见图3。
The result is a single element, and you can easily pull out the display child of that element and, with standard DOM operations, display it on the page as in Figure 3.
在类中，针对Web服务中的各操作的过程(函数、子元素或方法)定义：这些过程必须是公有的。
Within the class, a procedure (function, sub, or method) definition for each operation in the Web service: these procedures must be public.
RPGselect语句控制基于RPG操作将执行哪些子过程。
The RPG Select statement controls which sub-procedure will be executed based on the RPG operation.
Rope实现通常也将延迟对大型子串操作的求值，它的作法是引入子串节点。
Rope implementations also often defer evaluation of large substring operations by introducing a substring node.
interface元素及其子operation元素用于定义服务的操作。
The interface element and its child operation element are used to define a service's operations.
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.
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.
在递归模式下，它将查看哪些组包含其他组并允许执行递归操作，比如从当前组及其所有子组中删除用户。
In recursive mode, it notices which groups contain other groups and lets you perform recursive operations, such as removing a user from the current group and all subgroups.
您可以从某个元素中获得数据，操作其子元素，找出某个属性的值等，全部都是这方面的操作。
You could get the data in an element, work with its children, find out the value of an attribute... and that's really about it.
当大型强子对撞器达到它操作的最大限度时——这个月早些时候它为碰撞发生的速度设置了一项新记录——离奇古怪的结果必然会越来越频繁地意外出现。
As the LHC reaches its operational capacity-earlier this month it set a new record for the rate at which collisions occur-curious results are bound to crop up more and more frequently.
但是，直升机驾驶员通常坐在右边的座位上，因为坐右边右撇子更方便操作。
But more often helicopters are controlled from the right seat as it is more convenient for right-handeds.
注册页面上一下子提供了每种可能的操作导航，并且登陆页面上右边的广告比登陆表单还要突出。
The registration page offers every possible navigation option at once. And the login page has outstanding advertisements right next to the login form.
当这些子组件的终止操作完成时，该流程就会最终处于终止状态，同时产生“流程已终止”事件（21005）。
When the termination of these subcomponents is complete, the process ends in the terminated state and a "process terminated" event (21005) is generated.
可以操作声子并只让它们向一个方向流动的设备正在被建造，这是二极管的热等价物。
Far from it. Devices are being built that can manipulate phonons, allowing them to flow in one direction only, for example - the thermal equivalent of a diode.
子导航栏允许内部操作，例如，在日历视图中创建活动以及在活动视图中编辑或删除活动。
