“能够熟练运用游标卡尺来进行测量,并能准确读出测量值”是对高中学生掌握游标卡尺的要求,也是高考对基本仪器掌握程度的考查知识点之一.而对学生来说,准确读出测量值是难点.本文就此介绍游标卡尺的几种读法.一、主刻度读数+游标读数法这种读法分三步:①读出物体长度的整数部分 L_1,即游标卡尺上游标尺的零刻度线以左所对应的主尺毫米数;②读出 “Proficiency in the use of vernier caliper to measure, and can accurately read the measured value ” is a high school students master vernier caliper requirements, but also the college entrance examination on the basic instrument mastery of knowledge of one of the points. And for students, accurate reading The measured value is difficult.This paper introduces several reading Vernier Caliper I. First, the main scale reading + cursor reading method This reading is divided into three steps: ① read out the integer part of the object length L_1, that is, the vernier caliper scale Line to the left of the main millimeter corresponding to the number; ② read out
