To derive alternative flows, use activity diagrams.
为得到可选流程，使用活动图5。
We did this activity during the use case analysis (see Resources); we now derive the Solution Overview Diagram using the different use cases, as shown in Figure 1.
我们在用例分析（详见参考资料）的过程中完成了这项工作。 我们使用不同的用例来生成解决方案概要图表，如图1 所示。
Based on summarizing status of these researches, a method on how to derive test scenarios from the activity diagram of the actor is described that represents use case sequential dependencies and acti.
在总结研究现状的基础上，以应用举例的方式提出一种从描述系统用例间顺序依赖关系的活动图和用例实现的活动图中获取系统功能测试线索的方法。
These derive many unique properties: special mechanical, electric, magnetic, thermal, optical and chemical activity properties and so on.
