摘　　要：针对普适计算带来的智能物理世界构成实体的属性和行为特征,将知识重构与抽象模型(KRA模型)框架的感知过程扩展为初步感知和感知重构两步,使其能表示并区分所提出的智能环境下物理世界的不同属性域实体,得到智能环境下物理世界的层次模型.该模型统一定义物理实体,逻辑表示网络化实体,避免了重复感知.网络化实体间及物理实体和虚拟实体与网络化实体间的关系定义为逻辑连接关系,同时,可以将对以整个世界为推理空间的推理过程分解为在物理实体及连接构成的空间和在虚拟实体及连接构成的空间上更小规模的推理过程,降低了推理的复杂性.According to the attributes and behavior character of the entities composing the intelligent physical world brought by pervasive computing, the perception level of the KRA （knowledge reconfiguration and abstraction） model proposed by Saitta and ZuckeI to represent the static physical world was divided into primary perception and perception reconstruction. This can repi＇esent and distinguish the proposed entities of various domains to capture the hierarchical model of the physical world in intelligent environment. The presented extended model defines physical entities unitedly and represents networked entities logically to avoid reduplicate perception. The relationships between networked entities and between virtual entity and networked entity are logically defined to help the hierarchy of the model. In addition, the reasoning procedure based on the whole represented world can be decomposed into less-scale ones based on the space constructed by physical entities and their relationships and by virtual entities and their relationships, so that the complexity of reasoning isgreatly reduced.
