摘要
[目的/意义]文章针对基本主路径方法分析所得主路径过于单一,难以展示技术的不连续发展、技术的多分支组成,以及技术的多知识流融合等问题。[方法/过程]提出多源前向局域搜索路径、多汇逆向局域搜索路径、全局组合路径。[结果/结论]相比基本主路径分析方法,该方法在路径多样性、重要节点包含度和节点时间分布广度方面均有所提升。通过对富勒烯领域的分析证实了组合路径的可行性。
[Purpose/significance] The basic main path is single and difficult to show the discontinuous development of technology,multi-branch components of technology,and multi-knowledge flow integration of technologies.[Method/process]This paper proposes combination approaches of multi-source forward local search path,multi-sink reverse local search path and global combination path to boost the variety of main path.[Result/conclusion]Compared with the basic main path analysis method,this approach has improved the path variety,the important node inclusion,and the time distribution width of nodes.The analysis of fullerene field confirmed the feasibility of the method.
