摘　　要：科研案例教学法是推进科教融合、提升教学效果的重要举措。为了提升"燃烧学""消防工程"等课程中关于气体的扩散行为及气体泄漏过程中的多维浓度场特征等抽象知识点的教学效果,研制了气体泄漏多维浓度场模拟装置,并以甲烷泄漏实验为例,将其应用于课程教学中。结果表明,使用该装置后明显提升了学生对前述知识点的掌握程度,而且锻炼了学生的创新思维和培养创新能力。The teaching method of scientific research cases is an important measure to promote the integration of scientific research and teaching and enhance the teaching effect. In order to improve the teaching effect of abstract knowledge points such as the gas diffusion behavior in the courses of "Combustion science" and "Fire engineering" and the multidimensional concentration field characteristics in the process of gas leakage. a multi-dimensional concentration field simulation device for gas leakage is developed. By taking the methane leakage experiment as an example, the characteristics of its concentration gradient and its evolution are applied to the curriculum teaching. It is found that scientific research cases can significantly improve students’ mastery of the aforementioned knowledge points and can also train their innovative thinking and cultivate their innovative ability.
