| 摘 要： | 提出了知识的粒数、籽数和粒度的概念,证明了粗糙集理论中知识粗糙性与其所对应的粒度之间的单调关系,从而揭示了知识粗糙性与其所对应的知识的粒数、籽数和粒度之间的密切关系。知识粒度的概念从物理意义上反映了知识库中的知识颗粒状结构的本质。

| Abstract: | Proposed the eoncept of granule amount of knowledge,granule seed and granularity,proved its dull relation between knowledge roughness and its correspondent granularity in rough set theory, declared that knowledge roughness is closely related to granule amount of knowledge,granule seed of knowledge and granularity of knowledge. The concept of knowledge granularity in a sense of physics reflects the nature of granular structure of knowledge in knowledge base. |

| Keywords: | rough set theory knowledge roughness granularity of knowledge knowledge base |
