通常，用例描述足够描述一个简单用例中的工作流（“执行A，然后执行B，然后执行C”）。
It's not a good idea to clutter up the use-case description with these rules, but they have to be specified somehow to make the document accurate enough to be usable.
用例描述中最好不要包含这些规则，但应该以某种方式指定这些规则，以便使文档足够正确而能够使用。
In order to be able to test by means of use cases, besides the use case description and a use case diagram, additional information regarding specific aspects is required.
为了能够依靠用例来测试，除了用例描述和用例图之外，还需要有关特定方面的额外信息。
While you are in an analysis mindset, your use case description will generally address only the behavior of the system that is externally visible to an actor using the system.

具体研究包括：构建了以2000个数控机床造型设计案例为基础的案例库，并提出了规范的案例描述模式；
If you do not provide enough detail, then there is a real possibility of failure: the development team will have to re-discover the requirements even after they read your use-case description.
