Subject Intersection Features Research In Chinese Aerospace Field

With the continuous deepening of various major projects,such as manned space flight,lunar exploration,and large aircraft manufacturing,aerospace field has been influencing lots of aspects in social life in China.Through studying subject intersection in this field,we present subjects' connection and the structure about disciplines and knowledge in order to provide reference for the developing of Chinese aerospace cause.This paper analyses interdisciplinary features in Chinese aerospace field from the perspectives of scientific research and talent cultivation.As for scientific research,we take Web of Science category and Chinese library classification code as the judgment of subject category.And the subject intersection embodied by the category attribute of papers and their citations.The study on papers in English focuses on the analysis of characteristics and evolution under the action of various knowledge input subjects,while the research on papers in Chinese mainly analyzes interdisciplinary aerospace articles.On the other hand,through analyzing the core courses of postgraduate students' cultivation plans of 3 representative universities in China and constructing course intersection weight matrix,this study explores the intersection features of Chinese aerospace disciplines from the perspective of talent cultivation.There are some conclusions shown in this research.From the perspective of scientific research,first,there are multiple categories of co-occurrence in Chinese aerospace field,and the demand for external knowledge is higher.Second,subjects' connection is closer and closer,but the position of different subjects in the knowledge structure as well as knowledge themes present diverse trends.Third,several external subjects affect aerospace obviously,while new knowledge may appear with boundary disciplines.As for talent cultivation,we find,in the aspect of the curriculum setting,aerospace subjects in different research directions present various intersection characteristics with external(non-aerospace)disciplines.Besides,between external subjects and aerospace,there are one-to-many diverse and many-to-one focus course intersections.Compared with previous research on scientific papers,interdisciplinary features embodied in courses vary a lot.
