在高中物理的学习中许多同学对读数问题有非常模糊的认识,各种资料关于读数问题也众说纷纭,让学生无所适从.如何才能方便、准确的进行读数呢?众所周知,物理量包含三部分:准确值、估读值、单位.而估读的过程正是产生模糊认识的根源,下面我就谈一谈如何快速准确的进行测量工具的估读.刻度可以分成“精确刻度”和“辅助刻度” In the study of high school physics, many students have a very vague understanding of the reading problem. There are also many opinions about reading problems in various materials, which make students feel at a loss. How can we easily and accurately take readings? It is well known that physical quantities include three parts: the exact value, The process of estimating readings is the source of the fuzzy understanding. I will now talk about how to quickly and accurately estimate the measurement tool. The scale can be divided into “precision” and “additional” "
