摘　　要：分析了产品知识演化过程中耗散结构形成机理,基于知网文献,结合运行熵与关联熵构建熵模型,分析了近6年知识系统的结构稳定度以及系统运行效率,通过Citespace构建了盘式制动器知识演化的知识图谱,以可视化的方式分析了基于时间维度的知识演化路径,为分析产品的知识演化方向提供了不同的思路。The formation mechanism of dissipative structure in the process of product knowledge evolution was analyzed.Based on the knowledge network literature,the entropy model was built by combining operation entropy and association entropy,and the structural stability and system operation efficiency of the knowledge system in recent 6 years were analyzed.The knowledge graph of knowledge evolution of disc brake was constructed by Citespace.The knowledge evolution path based on time dimension is analyzed in a visual way,which provides different ideas for analyzing the knowledge evolution direction of products.

关 键 词：知识演化 耗散结构 熵 知识图谱
