科研合作关系一般是指科技活动参与者基于科技目标形成的一种科研合作关系网络。科研合作关系范式可以表征为关键词共现网络、单位合作网络、科研人才合作网络，通过构建“技术热点-单位-关键人才”科研合作选择框架可以有效地推进科研合作选择，预测未来合作的走向。以2006～2018年近10年间国家纳米技术科技报告为依据，综合文献计量、社会网络分析方法，对纳米技术领域的科研合作的网络结构进行分析和可视化。研究发现关系范式下的科研合作的选择可以在不同层面上进行。各个单位基于技术知识的优势，选择与其研究的热点和需求相关的单位进行合作。技术热点成为凝练合作选择的重要依据。关键人才尤为重要，不仅要与中心度高的科研人才建立连接，还要拓展与低限制度的“结构洞”人才进行合作，以推动交叉学科研究的开展。

Scientific research cooperation generally refers to a scientific research cooperation network formed by participants in science and technology activities based on scientific and technological goals. The research cooperation relationship paradigm can be characterized as a keyword co-occurrence network, a unit cooperation network, and a scientific research talent cooperation network. By constructing a "technical hotspot-unit-key talents" scientific research cooperation selection framework, can effectively advance research cooperation options and anticipate the future direction of cooperation.. Based on the national nanotechnology science and technology report in the past 10 years from 2006 to 2018, comprehensive literature measurement and social network analysis methods are used to analyze and visualize the network structure of scientific research cooperation in the field of nanotechnology. The study found that the choice of research cooperation under the relationship paradigm can be carried out at different levels. Based on the advantages of technical knowledge, each unit chooses to cooperate with the units related to its research hotspots and needs. Technical hotspots have become an important basis for cooperation choice. Key talents are particularly important, not only to establish connections with highly-centered scientific research talents, but also to expand cooperation with low-limit “structural hole” talents to promote interdisciplinary research.
