睡眠是人每天日常活动循环的一部分。人的睡眠分几个阶段，而这些阶段也是循环发生的。
Sleep is part of a person's daily activity cycle. There are several different stages of sleep, and they too occur in cycles.
因此，它的活动相对于新环境的外部循环发生了转移。
As a result, its activities are shifted relative to the external cycle of the new environment.

在对流程建模时，您有时会发现一个或多个活动应该属于某个循环或局部流程内部。
When modeling a process, you sometimes discover that one or more activities should belong inside of a loop or a local process.
您也可以在活动之间的控制流中实现分支或循环。
You can also implement branching or looping in the flow of control between activities.
这可以通过修改上述示例的循环来完成，以便调用活动直接调用外部服务，而不是调用事件处理程序。
This can be accomplished by modifying the loop of the example above so that the invoke activity invokes the external service immediately instead of invoking an event handler.
您唯一不能做的是创建循环，即将源活动链接到目标活动，而目标活动又链接回源活动(类似于无限循环)。
The only thing that you cannot do is to create a cycle, meaning the source activity links to the target activity which links back to the source (similar to an endless loop).
该工作流程实现了多种活动，决策点、排序、循环、业务规则实施点以及对服务的访问。
This workflow process implements various activities, decision points, sequencing, loops, business rule enforcement points, and access to services.
一个循环描述了一个流程内部一系列循环的活动。
A loop describes a repeating sequence of activities contained within a process.
一个更好的解决方案是将重复的活动放在一个循环中，如本文第1部分中的场景2。
A better solution would be to place the repeating activities within a cycle, as we discussed in Scenario 2 in Part 1 of this article.
即使在你休息的时候，身体也需要能量来维持他“潜在”的活动：如呼吸、血液循环、调节激素水平、细胞的生长与修复。
Even when you're at rest, your body needs energy for all its "hidden" functions, such as breathing, circulating blood, adjusting hormone levels, and growing and repairing cells.
第二个循环在活动目录模型中的所有关系上迭代，并呈现每个关系的适当部分。
The second loop iterates through all relationships in the Active Record model and renders the appropriate partial for each relationship.
另外，循环也可以从活动的单独输出条件开始，并在该活动或其他活动的单独输入条件中结束。
Alternatively, a cycle can begin in a separate output criterion of an activity and end in a separate input criterion of this or another activity.
由于跳转的源包含在循环流中，因此，此循环流中直接包含的所有活动都是有效的跳转目标。
Since the source of the jump is contained in a cyclic flow all the activities directly enclosed in this cyclic flow are valid jump targets.
在循环流活动中，连接器可以向后返回到某个以前的活动。
Within the Cyclic Flow activity, connectors can go backwards to a previous activity.
两个用户同时循环进行两个活动。
The two users will simultaneously do the two actions in a loop.
要发送其余的商品，我们只需再重复一次循环即可，因为调用发送组件的活动在循环的开始处。
To ship the rest of the items, we just need to let the loop iterate again, since the activity that calls to the shipping component is at the start of the loop.
由于不可能跳出结构化活动，因此淡出了循环流中未包含的活动。
As it is not possible to jump outside of structured activities the activities not contained in the cyclic flow are faded out.
While循环活动包含其他活动和一个条件。
A while loop activity contains other activities and a condition.
这样，在服务返回True时就会退出循环，接着运行Reply活动。
Thus, whenever the service returns true, the loop exits and the Reply activity runs.
在早期版本的Modeler中，您可以展开到容器活动，例如循环或局部流程。
In previous versions of Modeler, you could drill into a container activity such as a loop or local process.
当您希望在某个条件不再为True之前多次运行一组活动时，您可以使用While循环活动。
When you want a group of activities to run multiple times, until some condition no longer holds true, you can use a while loop activity.
LoopUntilShipped中出现红色“x”号是因为循环中没有活动。
The red 'x' in LoopUntilShipped occurs because there are no activities within the loop.
BPMN有两类重复活动，称作循环(DoWhile)和多实例(ForEach)。
BPMN has two types of repeating activities, called looping (DoWhile) and multi-instance (ForEach).
