Abstract: How to use the scientific research process to establish a test platform and support experimental teaching at the undergraduate level has been increasingly concerned by many universities.This paper introduces the advantages of the Department of Energy and Hydropower,Sichuan University,using the advantages of its own scientific research,and applies the comprehensive scientific test platform for thermal engineering to experimental teaching.Undergraduate students can directly contact and feel the relationship between the courses and scientific research in the ordinary experimental teaching activities,and it has received a good comprehensive effect,which is a successful example of scientific research to promote teaching.
