Then we draw the Sequence Flows to show the intended flow of execution so far.

接下来，我们绘制序列流，显示至此为止的目标执行流。

To begin wiring, click the Sequence Flow icon, as shown in Figure 15. Hover over the Start node.

要开始连接，单击Sequence Flow图标，如图15所示。

You will see the sequence of process flow.

您将看到流程工作流的序列。

What we're saying is, in order to do computation, we want to describe recipes, we want to describe this sequence of steps built on some primitives, and we want to describe the flow of control that goes through those sequence of steps as we carry on So the last thing we need before we can start talking about real programming is, we need to describe those recipes.

我们在说，为了做计算，我们想描述一个方法，想描述建立在,相同基本类型上的步骤序列，而且我们想描述经过我们设计的,步骤的序列的，控制流程,因此我们开始谈论真正的编程之前,的最后一件事是，我们需要描述一下那些方法。
