In UML 2 there are two basic categories of diagrams: structure diagrams and behavior diagrams.
在UML2中有二种基本的图范畴：结构图和行为图。
These diagrams are divided into three categories: structure diagrams, behavior diagrams, and interaction diagrams.
这些图被分成了三个类别：结构图，行为图，以及交互图。
Because system behavior is the result of objects sending messages to each other, sequence diagrams plot the course of those messages as they move from object to object.
因为系统行为是对象相互之间发送消息的结果，因此序列图绘制了那些消息在对象之间移动时的路线。
Behavioral diagrams, on the other hand, show the dynamic behavior between the objects in the system, including things like their methods, collaborations, and activities.
另一方面，行为图显示系统中的对象的动态行为，包括如对象的方法，协作和活动之类的内容。
The outcome of this phase is a set of BPM models represented in UML activity diagrams that describe the business process behavior.
此阶段的产物是一组BPM模型，这些模型以描述业务流程行为的UML活动关系图表示。
When the behavior of one or more key architectural elements is event-driven, modeling with State Diagrams can be especially useful in understanding that behavior.
当一个或多个关键架构要素的行为是事件驱动时，用状态图建模可以对理解该行为特别有用。
A second, more subtle reason is that the model, not the diagrams, becomes the expression of record for the structure, semantics, and behavior of the system.
其次，更细微的原因是模型，不是图，成为系统的结构、语义和行为的记录的表示。
In addition to the structural diagram, several other diagrams may illustrate behavior, such as sequence diagrams and state diagrams (see Figure 3).
除了结构关系图外，还可以通过其他几个关系图说明行为，如序列关系图和主题关系图(请参见图3)。
With the Simulation extension, you can simulate any UML behavior (activity diagrams, sequence diagrams, communication diagrams, or state diagrams).
有了模拟扩展，您就可以模拟任意的UML行为图了（活动图、序列图、交流图或者状态图）。
