摘　　要：[目的/意义]明晰大科学装置基金资助项目和资助论文的主题信息,为未来国家围绕重大设施的资助布局提供决策参考。[方法/过程]利用BERTopic在语义层面对大科学装置科学研究联合基金资助项目与资助论文进行主题提取。[结果/结论]研究发现,不同类型的大科学装置研究主题有其特定重点,研究主题分布和优势研究主题具有鲜明特征。依托大科学装置的研究型项目居多,与新原理、新方法与关键技术等相关研究项目较少。通过对比大科学装置科学研究联合基金资助项目主题和论文主题分析的异同,对基金的管理工作和未来大科学装置的资助布局提供一定的参考借鉴。[Purpose/Significance]To clarify the theme information of the projects and published papers funded by the large-scale scientific facility fund can provide a reference for the future research layout of large-scale scientific facility.[Method/Process]The BERTopic deep learning model was used to extract the topic of the projects and published papers funded by the joint research fund of large-scale scientific facility at the semantic level.[Result/Conclusion]The research finds that different types of large-scale scientific facility have their specific focus,and their distribution and advantages have distinct characteristics.Most of the research projects rely on large-scale scientific facility,and the research related on new principles,new methods and key technologies are less.The analysis of the similarities and differences of the project and the paper funded by the fund provides certain reference for the fund management and the layout of large-scale scientific facility in the future.
