| 中文摘要: |
| 利用2002年至2018年公开的德温特专利数据,分析了核科学与技术多元化应用的技术领域、区域分布、技术关联等。结果显示:543项同族专利中有501项属于中国,远超其他国家专利授权量的总和,按DWPI专利排名前十的机构中有4家位于中国,而且中国的专利主题领域十分广泛。出现次数最多的DWPI分类码代表的技术主题主要是核电技术、加速技术、核探测技术与辐射防护等。以专利共现为基础的社会网络分析结果显示,节点绝对中心度最高的10个DWPI分类码中有8个与中间中心度最高的DWPI分类码重叠,代表的技术主题主要包括核电、核探测技术、加速技术、辐射防护、铀矿分离与提取、核成像技术、工业废物和废水处理以及辐射发射装置等。除孤立点外,同质无向的核科学与技术专利多值网络可以划分为6个聚类和8个k-核。 |
| English Summary: |
| By using the DEWALT patent data published from 2002 to 2018, this paper analyzes the technical fields, regional distribution, and technical linkages of nuclear science and technology. The results show that 501 of the 543 family patents belong to China, far exceeding the sum of patent grants in other countries. Four of the top ten institutions ranked by DWPI patents are located in China, and China's technology field is very extensive. The technical themes represented by the most DWPI classification codes are mainly nuclear power technology, acceleration technology, nuclear detection technology and radiation protection. The social network analysis based on patent co-occurrence shows that 8 of the 10 DWPI classification codes with the highest local centrality of the node overlap with the DWPI classification code with the highest betweenness centrality. The represented technical topics mainly include nuclear power, nuclear detection technology, acceleration technology, radiation protection, uranium separation and extraction, nuclear imaging technology, industrial waste and wastewater treatment, and radiation emission devices. Except for isolations,the homogenous undirected network of nuclear science and technology patents can be divided into 6 clusters and 8 K-cores. |
