3.修正量法在测量中,由于标准器存在误差,当标准器与待测量进行比较时,该误差量将被引入测量结果中。为此,应从测量结果中予以扣除;也可在测量前作预扣除处理。从测量结果中扣除标准器误差的方法可按下式进行: [待测量的实际值]=[测量结果]+[修正值] 所谓修正值,就是改变符号的标准器误差值。
3 correction method In the measurement, due to the standard error, when the standard instrument to be measured when compared to the amount of error will be introduced into the measurement results. To this end, should be deducted from the measurement results; can also be deducted before the measurement processing. The method of subtracting the error of the standardizer from the measurement result is as follows: [actual value to be measured] = [measurement result] + [correction value] The so-called correction value is the change of the standard error of the sign.
