龚淑养2032螺旋测微器如何读数 -
湛寒很18458938250 ______[答案] 螺旋测微器又称千分尺,读数时应先从固定套管上读出微分筒边缘对应的毫米或0.5mm以上的读数,再读出固定套筒管上水平刻线对应微分筒上的毫米以下读数,要估读到最小刻度的十分之一,即0.001mm.
龚淑养2032螺旋测微器的读数______毫米;游标卡尺读数______毫米 -
湛寒很18458938250 ______[答案] 1、螺旋测微器的固定刻度为0.5mm,可动刻度为40.0*0.01mm=0.400mm,所以最终读数为0.5mm+0.400mm=0.900mm.2、游标卡尺的主尺读数为:3cm=30mm,游标尺上第6个刻度和主尺上某一刻度对齐,所以游标读数为6*0.1mm=0....
龚淑养2032(1)如图中给出的是用螺旋测微器测量一金属薄板厚度时的示数,此读数应为______mm.(2)如图所示为多用电表的指针在正确测量时的示数,若选择开关旋在... -
湛寒很18458938250 ______[答案] 螺旋测微器的读数:固定刻度是6mm 可动刻度读数为:12.3*0.01mm=0.123mm 则读数为:6+0.123=6.123mm(6.123-6.125) 因量程为25V,故最小分度为5V,则估读到同位, 则读数为:13V 欧姆档读数为:22*100=2200Ω 故答案为:(1)6....
