纵观近五年全国卷,常用测量仪器的读数是高考命题的重点之一,也是学生答题的难点之一。高中物理中常用的测量仪器有刻度尺、测力计(弹簧秤)、螺旋测微器、游标卡尺、天平、秒表、灵敏电流计、电压表、电流表、电阻箱、多用电表、温度计、大气压强计等。除了天平(初中阶段学习内容)、秒表(电子表代替)、温度计(热学选修)、大气压强(热学选修)、灵敏电流计(同电流表读数)等几种测量仪器外,刻度尺、测力计(弹簧秤)、螺旋测微器、游标卡尺、电压表、电
Throughout the past five years, the volume of the country, the commonly used reading instruments readings is one of the key points of the college entrance examination, but also one of the difficulties students answer. High school physics commonly used measuring instruments are scale, dynamometer (spring scale), spiral micrometer, vernier caliper, balance, stopwatch, sensitive galvanometer, voltmeter, ammeter, resistance box, multimeter, thermometer, barometer, etc. . In addition to the balance (junior high school learning content), stopwatch (electronic watch replacement), thermometer (thermal elective), atmospheric pressure (thermal elective), sensitive galvanometer (with ammeter readings) and several other measuring instruments, scale, dynamometer (Spring scale), screw micrometer, vernier caliper, voltmeter, electricity
