SymPy在“高等传热学”教学中的应用实践

Application Practice of SymPy in the Teaching of"Advanced Heat Transfer"

SymPy是Python的计算机代数系统库CAS,具有强大的符号计算功能,它免费开源,是商业数学软件很有潜力的替代方案。“高等传热学”理论教学中,绝大多数需要求解微分方程,有大量内容需要数学推导,这部分既是重点也是难点。在实践教学中,通过结合SymPy,实现教育方法现代化,可以方便地解决学生学习中部分数学上的困难。该文以几个导热问题为例,介绍了SymPy的具体应用方法,通过教学方式的改进,引导学生充分利用CAS,突破数学难点,增强学生课堂学习兴趣,提高学生的专业综合能力。

SymPy is a Python's computer algebra system(CAS)library and has powerful symbolic calculation func‐tions,and it is free and open source and is a promising alternative to commercial mathematics software.In the theo‐retical teaching of"Advanced Heat Transfer",it is necessary to solve differential equations in most cases,and a lot of content needs to be mathematically derived,which is both the key point and difficult point.In practical teaching,the realization of the modernization of educational methods by combining symPy can easily solve some of math‐ematical difficulties in students'learning.This paper introduces the specific application method of SymPy with sev‐eral heat conduction problems as examples,and guides students to make full use of CASs through the improvement of teaching methods,so as to break through mathematical difficulties,increase students'interest in class learning and improve students'professional comprehensive ability.
