虞衫畅3460物理游标卡尺和螺旋测微器怎么读数最好带图 -
谷坚瑗13486664738 ______[答案] 游标卡尺的读数 读数时首先以游标零刻度线为准在尺身上读取毫米整数,即以毫米为单位的整数部分.然后看游标上第几条刻度线与尺身的刻度线对齐,如第6条刻度线与尺身刻度线对齐,则小数部分即为0.6毫米(若没有正好对齐...
虞衫畅3460按照有效数字规则读出以下各测量仪器的测量值.螺旋测微器的读数______mm,游标卡尺的读数______mm. -
谷坚瑗13486664738 ______[答案] 1、螺旋测微器的固定刻度为0.5mm,可动刻度为38.6*0.01mm=0.386mm,所以最终读数为0.5mm+0.386mm=0.886mm,由于需要估读,最后的结果可以在0.885~0.8887之间. 2、游标卡尺的主尺读数为50mm,游标尺上第3个刻度和主尺上某一刻度...
虞衫畅3460物理游标卡尺和螺旋测微器怎么读数
谷坚瑗13486664738 ______ 游标卡尺读数的时候先看游标尺上的0刻度线对应的主尺上的刻度是多少mm与多少mm之间 比如11mm与12mm之间 那就是11mm 然后再看游标尺 如果是20个分度的那这个尺子精确度就是1/20=0.05mm 然后就看哪一条与主尺上的任意一条对的...
虞衫畅3460我明天要考试了,螺旋测微器和游标卡尺怎样读数,大家不要太罗嗦,给几道例题,我非常感 -
谷坚瑗13486664738 ______ 螺旋测微器的主轴上一小格是0.5毫米,游标卡尺是看主尺下面的可移动的那个尺子是多少毫米来确定它的精确度,例如是十毫米就是1/10如果是二十毫米就是1/20

谷坚瑗13486664738 ______ 螺旋测微尺:简单说就是半毫米一小档,一毫米一大档,一螺旋半毫米,分为50份,每份0.01mm直接相加即可,最后再估读一位. 游标卡尺:先看游标零点对应在主尺哪个读数上(当然是在亮度树之间,读最小那个),读之,再看游标上哪个线与主尺上的线对其或最近,然后就看那线占总游标中的分数(一般为x/10 x/20 或x/50),又知游标总为1mm,所以乘一下就好了,再加上原来的读数.一般不估读! 懂原理后可以灵活使用,不要拘泥于死步奏.

谷坚瑗13486664738 ______[答案] 游标卡尺找对齐的读,再乘以分度 螺旋测微器读了之后乘以0.01
虞衫畅3460请分别写出游标卡尺和螺旋测微器对应的读数(1)如图1, - -----mm;(2)如图2,------mm -
谷坚瑗13486664738 ______ 游标卡尺的主尺读数为104mm,游标读数为0.05*1=0.05mm,所以最终读数为:104mm+0.05mm=104.05 mm. 螺旋测微器的固定刻度读数为1.5mm.可动刻度读数为0.01*38.0mm=0.380mm,所以最终读数为:1.5mm+0.380mm=1.880mm;故答案为:104.05; 1.880
虞衫畅3460读出图中游标卡尺与螺旋测微器的读数,游标卡尺读数为 - -----cm,螺旋测微器读数为------mm -
谷坚瑗13486664738 ______ 1、游标卡尺的主尺读数为:1.6cm=16mm,游标尺上第10个刻度和主尺上某一刻度对齐,所以游标读数为10*0.05mm=0.50mm,所以最终读数为:16mm+0.50mm=16.50mm=1.650cm.2、螺旋测微器的固定刻度为5.5mm,可动刻度为19.0*0.01mm=0.190mm,所以最终读数为5.5mm+0.190mm=5.690mm,由于需要估读,最后的结果可以在5.689~5.691之间.故答案为:1.650,5.689~5.691
