It models the basic process and only simple directed edges that control the flow of processing logic from one activity to the next.
该模型包括一些基本的过程以及简单的有向图，这些边框控制着从一个活动到下一活动的处理逻辑流程。
You can only add additional control flow inputs and outputs to an activity after dragging and dropping it into a reusing process model.
当您将某个活动拖放到采用重用方法的流程模型中之后，只能向该活动添加更多的控制流输入和输出。
Examine multiple occurrences of the same reused activity for redundancy and possible improvements of the control flow of the process.
检查同一个被重用活动是否多次出现，以找出冗余，以及是否有可能对流程的控制流做出改进。
In case of a backward jump, the navigation continues at the target activity, and, as a result, some activities may be executed again, that is depending on the control flow.
对于向后跳转，导航将在目标活动继续执行，结果可能会再次执行某些活动，这具体取决于控制流。
You can use gateway form and activity form interchangeably for process models that contain only control flow, as we discussed in the Background section in Part 1 of this article.
流程模型中的网关形式和活动形式可以互换使用，如本文第1部分中的背景部分所述。
These operations will not be accepted unless the processPurchaseOrder activity is running and the flow of control has reached the two accept call actions.
除非processpurchaseorder活动正在运行，并且控制流程已经到达两个接收呼叫行动，否则这些操作将不会被接收。
Note that these operations will not be accepted unless the processPurchaseOrder activity is running and the flow of control has reached the two accept Call actions.
请注意除非processpurchaseorder活动正在运行，并且控制流程已经到达两个接收呼叫行动，否则这些操作将不会被接收。
These operations will not be accepted unless the processPurchaseOrder activity is running and the flow of control has reached the two Accept Call actions.
这些操作将不会得到接受，除非processPurchaseOrder活动正在运行而且控制的流程达到了两个AcceptCall 操作。
First, you need to add an assign activity to your process control flow before the invoke activity (see Figure 10).
首先，在调用活动之前，您需要将分派活动添加到流程控制流(请参见图10)。
UML activity diagrams can be used to describe the control flow of different abstract levels and are very suitable for modeling system behaviors.
UML活动图可以表示不同抽象级的控制流，很适合用于对系统的行为建模。
Hepatic blood flow earlier perfusion phase, time-activity curve(TAC), hepatic blood pool phase(plane and tomography), CT and color ultrasound were compared as control group.
再与肝血流灌注相的早期充盈、时间活性曲线（TAC）、肝血池（平面及断层）显像、CT和彩超检查作对照。
Hepatic blood flow earlier perfusion phase, time-activity curve(TAC), hepatic blood pool phase(plane and tomography), CT and color ultrasound were compared as control group.
再与肝血流灌注相的早期充盈、时间活性曲线（TAC）、肝血池（平面及断层）显像、CT和彩超检查作对照。
