【摘要】 将专利计量方法应用于技术预见当中,以专利分类号为研究对象,分别采用频次分析法和共类分析法对国内冶金领域的技术热点与前沿进行计量分析。根据定量化的统计分析结果,不仅发现了"合金"、"金属材料镀覆"等一些热门的技术主题,而且比较直观地反映出不同技术主题之间的关联及强度。这种技术关联在一定程度上代表着冶金领域各个技术主题不断融合与分化的发展趋势,在这些交叉点上往往孕育着新的技术生长点。更多还原

【Abstract】 Combining patent bibliometrics with technology foresight and considering patent classification codes as the statistical indicators,this paper analyzes the focuses and trends in the field of metallurgy by means of frequency analysis and co-classification analysis.It is found that "alloys","production or refining of metals","pretreatment of raw materials" and "metallic coating" are the active themes in the field of metallurgy.Those three subclasses are not only the hot domains but also represent the trends to some extent.The visualization of co-classification network directly demonstrates the relatedness and its intensity between different technological subjects.According to the development law of science and technology,it often helps breed new technology subjects at those interdisciplinary points.更多还原
