通常，您会注意到工作流中的两个用例相互之间很相似，尽管它们之间还有一些小差异。
Often, you'll notice that two use cases appear to be similar to each other, though there are minor differences in workflow.
具有相同工作流的两个用例当然是等价的，但我还不知道我的问题是否属于这种情况。
Two use cases that turn out to have the same workflow are certainly equivalent, but I don't yet know whether that will be the case.
如早先提到的，从与用户的交互那里重新获得的用例的事件流不太可能完整。

It is clear how supplementary specifications affect the use-case flow of events.
尽管用例获取用户和任务的一般化观点，但是依据具体的工作流，情境描述具体的用例实例。
