摘要:

为了全面了解对撞机相关技术的构成与发展趋势,本文分析近三十年对撞机技术相关的专利和论文数据,在统计其年度、国家、机构分布情况的基础上,分别利用Context-LDA模型和LDA主题模型,研究专利和论文的主题分布及热点主题,进一步利用相似度指标(JS距离)及信息熵,分析论文主题的演化。结果表明,日本和美国分别是专利和论文产出量最高的国家,中国位居前列且近些年的成果数量快速增加;加速系统电极电路、束流注入、超导装置、真空系统、射频腔等是专利中热度较高的技术主题。与大型强子对撞机相关的技术主题在各时段论文中均是研究热点,其中热度较高的主题有磁体与螺线管、迳迹系统、束流腔、超导磁体、量热仪等;对撞机技术领域的研究主题朝着更加均衡多样化的趋势发展。建议中国继续提升在该领域的成果产出数量;增大热点技术领域的研发力度;科研单位应寻求与优势企业的研发合作,或促进产学研一体化发展;加快对是否建设大型对撞机的研判工作。

Abstract:

In order to fully grasp the technical composition and development tendency of the collider, this paper analyzes the patents and papers related to the collider technology in the past 30 years. The statistics on the annual, national, and institutional distributions of the patents and paper are presented firstly. Then, this study uses the Context-LDA model and LDA topic models to study the topic compositions and hot topics of patents and papers respectively. Further, by using similarity index (JS distance) and information entropy, this study analyzes the topic evolution of papers. The results show that Japan and the United States are the countries with the highest amount of patents and papers respectively. China ranks in the forefront and the output of achievements has increased rapidly in recent years; electrode circuits of accelerated system, beam injection, superconducting devices, vacuum systems, radio frequency chambers, etc., are the most popular topics of the patents. The technical topics of papers related to the Large Hadron Collider have been hot topics at different times. Among them, the hot topics include magnets and solenoids, trace systems, beam cavities, superconducting magnets, calorimeters, etc.. Research topics in the field of collider technology are developing towards a more balanced and diversified trend. This paper recommends that China continues to increase the number of output in this field, increases the research and development (R&D) efforts of hot technology fields; scientific research institutions should seek R&D cooperation with superior enterprises, or promote the integrated development of production, education and research, and speed up the research to determine the construction of a large-scale collider.
