摘　　要：采用共词聚类与可视化方法对自中国知识资源总库建库至2021年10月30日间发布的研究生学位论文进行统计分析,提取了我国机动车尾气污染研究的6类热点:尾气污染特征与交通环境管控、尾气余热发电技术与强化换热建模仿真、基于催化氧化的尾气治理材料与技术、尾气形成机制及等离子体治理和遥感监测技术、基于非分光红外的尾气检测技术、掺加纳米二氧化钛的沥青路面用于光催化降解尾气,其中前2类热点的地位较核心且成熟度较高。Based on the methods of co-word clustering and visualization,the statistical analysis was made on the Graduate Dissertations published from the establishment of Chinese National Knowledge In⁃frastructure to October 30,2021.The framework of research hotspots on vehicle exhaust pollution in China was established.The research focused on the pollution characteristics of vehicle exhaust and traf⁃fic environment control,waste heat power generation technology and the modeling and simulation of en⁃hanced heat transfer,the material and technology of vehicle exhaust treatment based on catalytic oxida⁃tion,the formation mechanism and plasma treatment of vehicle exhaust and remote sensing monitoring technology,vehicle exhaust detection technology based on non-spectroscopic infrared technology and the application of nano-TiO2 photocatalytic technology in asphalt pavement material to the degradation of vehicle exhaust.Among these six themes,the first two themes were more core and mature.
