通过剖析一些典型例题,指出在建立物理模型过程中可能发生的错误,并阐述正确建立物理模型的方法。文中强调善于把实际问题的“原型”转化成物理或数学模型,将是物理教学中面临的一个重要问题。
By analyzing some typical examples, we point out possible errors in the process of establishing a physical model, and elaborate methods for establishing physical models correctly. The article emphasizes that being good at translating the “prototype” of a practical problem into a physical or mathematical model will be an important issue facing physics teaching.
