比值定义法是高中物理概念定义的一种常用方法,也是分析和研究相关物理问题的基本手段.纵观高中物理知识的构成,可知其中大多数的物理概念均是借助比值定义法来进行定义.本文以比值定义法为研究对象,注重探究了其物理功能,以期为中学物理教学提供参考.1明确概念含义,奠定扎实基础所谓的比值定义法,就是指借助两个物理量之比来 The ratio definition method is a commonly used method to define high school physics concepts and is also the basic method to analyze and study related physics problems.Considering the composition of high school physics knowledge, we can see that most of the physical concepts are defined by the ratio definition method. In this paper, the ratio of the definition of law as the research object, pay attention to explore its physical function, in order to provide reference for physics teaching in middle school.1 Clearly conceptual meaning, to lay a solid foundation The so-called ratio definition method refers to the ratio of the two physical quantities
