摘要
代数是人们描述自然规律的一个极为重要的数学工具,但它自身的抽象性又使得初学者很难掌握这一数学工具。理论力学是物理系本科生的第一门理论课程,对运用数学工具处理物理问题的训练明显较普通物理加强。我们尝试在理论力学课的刚体力学一章采用代数讲法,从而使抽象的数学理论与具体的物理图像有了直接的对应,并为后续专业类课程学习打下了良好的基础。
Algebra is a very important mathematical tool in physics research and description.But it is also very difficult for beginners to learn due to its abstraction.Theoretical mechanics is the first theoretical course of physics undergraduates,and its training of using mathematical tools to deal with physical problems is more important than that of general physics.We try to use algebraic method to teach the fixed point rotation of rigid body in theoretical mechanics course.It can make a connection between the abstract mathematical theory and specific physical image,and lay a solid foundation for the follow-up courses.
