摘　　要：在开展第二维里系数测定的实验教学过程中,在学生完成了CO_(2)第二维里系数实验测定的基础上,依托课程思政来激发学生兴趣,进行实验教学计划外的延展与进阶性学术训练,引导与启发学生进一步思考如何进行CO_(2)第三维里系数的测定这一问题。学生经过思考研究与讨论后,提出了基于Burnett法进行第三维里系数实验测定及数据处理方法,对实验数据进行有效处理后得到了CO_(2)的第三维里系数,并与相关文献值进行了对比分析,验证了数据合理性及方法有效性。通过该实验项目的启发式思维及延展性训练,提升了实验教学效果,强化了学生解决复杂工程问题的能力,学生受到了学术研究锻炼。In the course of the experimental teaching of measuring the second Virial coeff icient,we stimulated the students’interests by ideology and politics of curriculum and carried out the extended academic training out of the basic experimental teaching plan on the basis of the second virial coeff icient measurement of CO_(2),and to guide and inspire the students to further thinking how to measure the third virial coeff icient of CO_(2).After guiding the students to think,study and discuss,an approach based on Burnett method is proposed to measure the third virial coeff icient and to process the experimental data effectively,the rationality of the data,and the validity of the approach were verif ied by comparing with the related published literature.Through the heuristic thinking and extension training,for students,their learning eff iciency was improved,their ability of solving complex engineering problems was strengthened,and their academic research ability were well trained.
