摘　　要：“溶液吸附法测固体比表面积”实验是物理化学学习中理论到实践应用的良好体现。综合实验改进是在原有的实验教学基础上让学生自己动手合成超交联聚合物并通过溶液吸附法测算该材料的比表面积,此改进实验主要包括材料合成、结构表征和实际应用三个部分,形成一个完整的研究过程,训练学生实验操作技能,培养学生创新实践精神,实现化学实验课程的教学目标,达到综合实验锻炼化学专业本科生理论-实践相结合,知行合一的创新育人目的。The experiment of“measuring the specific surface area of solid by solution adsorption method”is a good embodiment of the theory to practice application in physical chemistry learning.Based on the original experimental teaching,this comprehensive experiment is improved by allowing students to synthesize the hypercrosslinked polymer by themselves and measure the specific surface area of synthetic material by solution adsorption method.The improved experiment mainly includes three parts:material synthesis,structural characterization and practical application.It forms a complete scientific research process so as to train students’experimental operation skills,cultivate students’innovative practice spirit,realize the teaching objectives of chemical experiment course and achieve the innovative education purpose of combining theory with practice and combining knowledge with practice for undergraduates majoring in chemistry through comprehensive experiment.
