摘　　要：文中给出了在DOOD中类的定义和表示 ,并以此为基础介绍了利用规则生成派生类。着重讨论了在类等级中派生类的定位和实现问题 ,提出了一种定位算法 ,最后讨论了基类和派生类之间的链接方法。This paper introduces the definition and denotation of classes in DOOD,then discusses the derived classes created by rules based on them. It mainly discusses the orientation and implementation of derived classes in class hierarchy,and two possible links between base classes and derived classes. An algorithm of orientation is also put forward.
