一砂一世界,一水一海洋。物理典型模型就是物理世界中的一粒砂、一滴水。每一个典型模型都与一定的物理原理、定理或定律相联系;典型模型所给出的物理机制往往是许多物理现象共同的本质和基础;典型模型既是物理知识的综合,又是能力和方法的载体。伟大的物理学家们,在各自的研究领域里都建立了一系列自己“最拿手”的物理模型。当遇到一些陌生的、复杂的问题时,就可联系上相应的模型,从而迅速地把握问题的实质。中学生学习物理,解决物理问题的过程也就 A sand and a world, a water and a sea. The physical model is a sand, a drop of water in the physical world. Each typical model is related to a certain physical principle, theorem or law. The physical mechanism given by a typical model is often the essence and foundation of many physical phenomena. The typical model is not only a combination of physical knowledge but also capabilities and methods Vector. The great physicists have built a series of their own “best-of-breed” physical models in their fields of study. When encountering strange and complicated problems, you can contact the corresponding model to quickly grasp the essence of the problem. Middle school students learn physics, the process of solving physical problems also
