输出是一个表征图而不是系统发生图。

The output is a phenogram rather than a phylogram.

序列图是如此好用的理由是，因为它按照交互发生的时间顺序，显示了系统中对象间的交互逻辑。

The reason the sequence diagram is so useful is because it shows the interaction logic between the objects in the system in the time order that the interactions take place.

我已经介绍了序列图的基础，应该使你可以为将会在系统中通常发生的大部份交互建模。

I've covered the basics of the sequence diagram, which should allow you to model most of the interactions that will take place in a common system.
