摘　　要：[目的/意义]展现一个学科与其他学科之间知识吸收和知识扩散的完整过程,揭示学科知识发展的来龙去脉。[方法/过程]利用国际权威引文数据库Web of Science,依据Web of Science学科类别划分标准,以Information Science&Library Science(以下简称ISLS)为例,选择2006-2010年和2011-2015年两个时间段,建立三个数据集(施引文献集、原始文献集、被引文献集),利用双图叠加可视化的方式探析ISLS与其他学科在期刊层面的知识吸收过程;利用知识扩散广度、强度和速度三个指标揭示ISLS与其他学科之间知识扩散现状和发展趋势。[结果/结论]在两个阶段内,ISLS主要吸收期刊类群心理、教育、社会的知识,知识来源学科主要为计算机科学学和管理学,在相应时间段内,知识扩散广度与时间呈对数函数关系,知识扩散速度与时间呈指数函数关系,ISLS向其他学科的知识扩散强度呈幂率分布。[ Purpose/Significance ] This research is intended to explore the complete diffusion process of knowledge absorption and knowledge diffusion among different disciplines and reveal the knowledge development rules of disciplines. [ Method/Process] Using the international authoritative citation database Web of Science and its classification criteria of WOS subject categories, choosing the discipline of Information Science ＆ Library Science （ISLS） as an example, the two time periods of from 2006 to 2010 and 2011 to 2015 are specifically chosen for further analysis, and three data sets （ set of citing documents, set of original documents, and set of citations documents） are established, then the knowledge absorption process of ISLS and other disciplines in the journal level is analyzed by the Dual-Map Overlays. Using the three indicators of knowledge diffusion width, strength and speed, the development trend of knowledge diffusion is revealed. [ Result/Conclusion] The results show that in the two stages, the journal category for being absorbed into the main ISLS journal group includes psychology, education, society, the main knowledge absorption source domains are computer science and management science. And, in the corresponding period, knowledge diffusion scope and time shows a Logarithmic function relation, knowledge diffusion speed and time presents an exponential function relationship and the intensity of knowledge diffusion from ISLS to other disciplines has a power-law distribution.
