高中物理(统编教材)下册,关于《原子的定态和能级》这一节,涉及玻尔原子模型的有关量子规律,这是合乎“教材内容现代化”要求的,然而这一节公式多(包括从习题中导出的),且每个公式中所含的物理量也多,学生学习这些公式普遍感到有些困难,为有利于学生了解和掌握,本文拟以最简单的氢原子模型为例,从教材中涉及的一些基本公式入手,对有关量的比例关系作一下分析。
The second volume of the High School Physics (compiled textbooks), on the section “The stationary state and energy level of the atom”, involves the quantum laws of Bohr’s atom model. This is in line with the requirements of the “modernization of teaching materials”. However, this There are many formulas (including the ones derived from the exercises), and each formula contains many physical quantities. Students generally feel some difficulties in learning these formulas. To help students understand and master, this paper proposes the simplest hydrogen atom model. For example, starting with some of the basic formulas involved in the teaching materials, we will analyze the proportional relationship of the relevant quantities.
