摘　　要：在借鉴元对象工具思想的基础上,给出了装配特征的本体表达框架。采用四层元数据体系表达装配特征,并用网络本体语言描述装配特征本体信息。基于上述表达框架,提出了面向虚拟产品的全息语义模型。给出了模型数据的存储结构以及模型信息的重组算法。最后,通过应用实例验证了所提出的理论和方法。An expression architecture for assembly feature based on ontology was presented by using Meta Object Facility （MOF）. Four-level meta-data architecture was used to express assembly feature and Web Ontology Language （OWL） was used to describe assembly feature ontology information. Holographic semantic model oriented to virtual product was presented based on the expression architecture of assembly feature. The storage structure for model data and a reorganization algorithm for the model, were provided. Finally, the proposed theory and methods were manifested by application examples.
