采用多次测量降低随机效应对测量结果的影响、用角尺测量垂直度时,将角尺反转180°再次测量,取两次测量结果的算术平均值消除系统效应对测量结果的影响以及采用多面互比法,利用最小二乘法测量平晶的平面度等,都是计量中常用的方法。本讲主要介绍与长度计量有关的几种常用的测量方法。
Use multiple measurements to reduce the impact of random effects on the measurement results, the verticality measured by the square, the angle of 180 ° and then re-measure, take the arithmetic mean of the measurement results to eliminate the effects of system effects on the measurement results and the use of multi-faceted Than France, the use of least square method to measure flatness flatness, etc., are commonly used method of measurement. This talk mainly introduces some commonly used measurement methods related to length measurement.
