摘　　要：能源与环境工程专业是伴随我国经济高速增长所面临的能源紧缺和“碳达峰”“碳中和”环境压力问题的双重挑战而设立的战略性新兴学科专业。针对专业课程涵盖领域广泛的特点,从自身特色和优势出发,将先进的低场核磁共振仪器以及自主研发的实验装置成果转化到本科基础和创新实验教学中,主要开展“流体弛豫时间与扩散系数测量”“多孔介质孔隙度测量”“油水相分辨实验”“两相流体渗流实验”“水合物生成与分解实验”等系列实验项目,培养学生掌握最前沿的科学分析仪器的使用能力,锻炼学生从科研的角度来思考、设计、观察、总结实验项目,并加强独立的分析和解决问题的能力,满足社会对“研究型、创新型”高素质综合人才的需求。With the rapid growth of economies,the major of energy and environmental engineering is a strategic emerging discipline established under the background of the dual challenges of energy shortage and environmental pressure related to carbon peaking and carbon neutralization.The outstanding feature of this major is that the course covers a wide range of fields.Based on its own characteristics and advantages,it transforms the achievements of advanced low-field NMR instruments and independently developed experimental devices into undergraduate basic and innovative experimental teaching,which includes the measurement of fluid relaxation time and diffusion coefficient,the porosity measurement of porous media,the experiment of oil-water phase resolution,the experiment of two-phase fluid flow in porous media,the experiment of hydrate formation/decomposition,and other experimental projects.Above teaching projects cultivate students to master the application ability of the most cutting-edge scientific analysis instruments.At the same time,it trains students’ability to think,design,observe and summarize experimental projects from the perspective of scientific research,and independently analyze and solve problems,so as to meet the social demands for research-oriented and innovation-oriented high-quality comprehensive talents.
