中文摘要	针对机动车污染这一典型大气污染源,结合我国当前大气污染现状以及环境学院近年来在大气污染控制方面的研究成果,采用当前国际上主流的选择性催化还原烟气脱硝技术,自主设计搭建了包括尾气检测与催化剂制备、温度控制、气体配制、催化转化、反应检测等模块在内的综合教学实验系统。采用真实机动车进行排放检测,使学生对机动车污染排放与工况的关系有更深体验。通过比较不同催化剂种类、程序升温过程(升温时间、始末温度、升温速度)、反应时间等参数对催化效果的影响,从而培养学生浓厚的科研兴趣,启发科学思维,推动大气实验课程建设和环境专业复合型拔尖创新人才的培养。; In order to control the motor vehicle pollution,combined with the current status of China's air pollution and the research progress in recent years,the selective catalytic reduction technology was used and the integrated experimental system of automobile exhaust emissions test and catalytic conversion was designed independently,including vehicle emission detection,catalyst preparation,temperature control procedure,gas preparation and catalytic conversion reaction detection.In this system,using real motor vehicle to test the vehicle emissions is helpful for the students to understand the relationship between the working conditions and the pollution emission.By comparing the influence of the different types of catalyst,the temperatureprogrammed process(heating time,original temperature,and heating rate),the reaction time and other parameters on the catalytic effect,it is helpful to increase the students' scientific interest,inspire scientific thinking,and promote the atmospheric experiment course construction and further cultivate environmental professionals and top-notch innovative talents.
