摘要
事物分类的标准是一个由来已久的话题．文中将事物的特征分为一般特征和本质特征，认为事物应该依据其结构、行为、性质、职能诸方面的本质特征进行分类．使用了角色的概念来综合反映事物各方面的本质特征，并在角色分类的基础上建立了对象类型之间的子类型关系．
People have been discussing the classification criteria of things for a long time.Features of things are divided into essential features and general features,and it is submitted that the classification of things should be based on essential features of structure,quality,behavior and function.The concept of role is used to represent these essential features synthetically,and the subtype relations among object types on the foundation of role classification are established.
