摘要: We discuss an approach to a theory of physical objects and present logical based on fundamental distinction between their substrates, i.e. chunks matter regions space . The purpose is establish the basis general ontology space, for domain mechanical artifacts. An extensional mereological framework assumed whereas are allowed change spatial material substrate while keeping identity. Besides parthood relation, simple self-connected region congruence (or sphere) adopted as primitives description space. Only threedimensional in domain. This paper revision slight modification [Borgo et al. 1996].
