购买理由

      买这个游标卡尺，是平时偶尔测量问题尺寸，有时候用不锈钢直尺，不方便，也不准确。就想买一款测量方便 又比较准确的游标卡尺。想着耐用一点，就没有考虑那种二三十元的塑料材质的 游标卡尺，最后从价格评论等方面，选择了本次晒单的鸣固游标卡尺。京东自营报价109元。

总结

这个游标卡尺，用起来可以，价格不算特别便宜。产品细节方面，还有待改善，比如标签问题和全英文的说明书。

慎阁邵4939游标卡尺怎么用? -
蔡耐奖18799989672 ______ 尺身和游标尺上面都有刻度.以准确到0.1毫米的游标卡尺为例,尺身上的最小分度是1毫米,游标尺上有10个小的等分刻度,总长9毫米,每一分度为0.9毫米,比主尺上的最小分度相差0.1毫米.量爪并拢时尺身和游标的零刻度线对齐,它们的...

慎阁邵4939下面的尺叫什么来着?怎么读数? -
蔡耐奖18799989672 ______ 游标卡尺,由主尺和附尺构成.尺身【主尺】和游标尺【附尺】上面都有刻度.以准确到0.1毫米的游标卡尺为例,尺身上的最小分度是1毫米,游标尺上有10个小的等分刻度,总长9毫米,每一分度为0.9毫米,比主尺上的最小分度相差0.1毫米.量爪并拢时尺身和游标的零刻度线对齐,它们的第一条刻度线相差0.1毫米,第二条刻度线相差0.2毫米,……,第10条刻度线相差1毫米,即游标的第10条刻度线恰好与主尺的9毫米刻度线对齐.

慎阁邵4939游标卡尺测量长度时如何读数?游标本身有无估读数? -
蔡耐奖18799989672 ______ 没有估读,因为它的下端刻度是正对的.读的时候先看上面,然后你看下面的刻度,有分度的,就是1除以分度,然后换单位加起来就可以了

慎阁邵4939游标卡尺怎么读数?
蔡耐奖18799989672 ______ 好学的很,上面的数,和直尺一样,主要就是下面的数,量一个产品的尺寸,看下面的那一个竖杠和上面的对直就是加多少丝.比如一个产品要做30加20丝,30就是3厘米,30多一点点就是下面的2毫米对直上面的就可以了.

慎阁邵4939游标卡尺多余的尺寸怎么算 -
蔡耐奖18799989672 ______ 网上给你解释游标卡尺的原理,难得打字.你先看游标卡尺的副尺的左边第一条线对着主尺的那个数字(超过33),再看副尺上,哪条刻度线对准主尺的刻度线.再来判读零点几毫米

慎阁邵4939游标卡尺是怎样读数的?副尺上的数怎么读? -
蔡耐奖18799989672 ______ 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(若没有正好对齐的线,则取最接近对齐的线进...

慎阁邵4939物理 游标卡尺的精度 怎么计算 -
蔡耐奖18799989672 ______[答案] 游标卡尺的精度是由卡尺游标上的刻度与主尺上的刻度之间的刻度值的大小来确定的,比如0.02mm精度的游标卡尺上,主尺上49mm刚好等于副尺上50格,副尺每格长为=0.98mm.主尺与副尺的刻度间相关为1-0.98=0.02mm,因此它的...

慎阁邵4939游标卡尺怎么读数 -
蔡耐奖18799989672 ______ 先读大的刻度,就像读尺子一样,确定能够确定的刻度值,还有一些是大的刻度读不出来的,要靠下面的游标.游标部分一般分几个格,举个例子,如有个游标卡尺,大刻度下最小单位是mm,游标上有50个格,则游标上50个单位共1mm.一个...

慎阁邵4939精确到0.02毫米的游标卡尺下面几个刻度? -
蔡耐奖18799989672 ______[答案] 25等分: “还有其它间隔的游标卡尺,通常为了简化刻度工序,选用比1cm大的距离作为细分时间隔.当制造读数达到0.0002cm的游标卡尺时,常把主尺(刻度标定为0.05cm)上的1.2cm的间隔在游标上细分为25等分.”

慎阁邵4939求有关游标卡尺的物理问题用游标卡尺测物体是,卡尺的数值为什么会等于物体半径值的小数点后面的数值?就是下面那个卡尺测出的值. -
蔡耐奖18799989672 ______[答案] 下面的游标尺共有10格,但每格只有0.9mm,总长为9mm,与主尺相差1mm,如果游标尺的第一格与主尺的第一格对齐,说明尺子只移动了0.1mm.(这是10格的) 20格与主尺相差0.05mm,50格的与主尺相差0.02mm
