基准尺 meaning in Chinese
reference meter
Examples
- On the basis of request to untouch measure online , this paper put forward the method of " datum dimension precision back " , and then the mathematics model is being established
测试精度要求达到国家标准it6级。基于在线非接触测量的要求，本论文提出了基准尺精确后退的想法，并以此建立数学摸型。 - Analyze item by item the position of unintact cycle , the running clearance of unintact cycle , locking - deform , datum dimension regulating , repeatly install , power voltage wave and marking running etc . at the same time , we give the calculating formula to calculating the running marking random error , and use it to calculate the system error of big diameter measure instrument - - datum dimension frame error , gyro - wheel diameter error , error caused by circumstance temperature , error caused by backing distance , angle error , delay error of data collecting circuit , lathe main shaft running error , workpiece install partial error
对不完整圆的位置、不完整圆的转动间隙、锁紧变形、基准尺调整、重复安装、电源电压波动、标记转动等随机误差进行了逐项分析，并给出转动标记随机误差的计算公式。对大直径测量仪的系统误差?基准尺尺架误差、滚轮直径误差、环境温度引起的误差、后退距离引起的误差、角度误差、数据采集电路延时误差、车床主轴回转误差、工件安装偏心误差分别进行了计算，最后对误差进行合成。 - Especially , the idea of " datum dimension precision back " is being put forward , and this idea is being realized by backing composition composed by outer - diameter micrometer , airproof shafting , microwatch . at the same time , use " non - lock " to replace " lock " , this way make the system compact , eliminate many bigger error and resolve th
尤其是提出了基准尺调整后精确后退的思想，并通过外径百分尺、密珠轴系、千分表组成后退机构加以实现。同时以“无锁”代“锁” ，使系统结构紧凑，受力小，消除了多项较大误差从而解决了测试精度低的关键问题。
