问题: 有关计量学的科技英语翻译
麻烦高手给翻译一下,谢谢了先。
1、measurement error
measured quantity value minus a reference quantity value
NOTE 1 The concept of ‘measurement error’ can be used both
a) when there is a single reference quantity value to refer to, which occurs if a calibration is made by means of a measurement standard with a measured quantity value having a negligible measurement uncertainty or if a conventional quantity value is given, in which case the measurement error is known, and
b) if a measurand is supposed to be represented by a unique true quantity value or a set of true quantity values of negligible range, in which case the measurement error is not known.
NOTE 2 Measurement error should not be confused with production error or mistake.
2、random measurement error
component of measurement error that in replicate measurements varies in an unpredictable manner
NOTE 1 A reference quantity value for a random measurement error is the average that would ensue from an infinite number of replicate measurements of the same measurand.
NOTE 2 Random measurement errors of a set of replicate measurements form a distribution that can be summarized by its expectation, which is generally assumed to be zero, and its variance.
NOTE 3 Random measurement error equals measurement error minus systematic measurement error.
3、systematic measurement error
component of measurement error that in replicate measurements remains constant or varies in a predictable manner
NOTE 1 A reference quantity value for a systematic measurement error is a true quantity value, or a measured quantity value of a measurement standard of negligible measurement uncertainty, or a conventional quantity value.
NOTE 2 Systematic measurement error, and its causes, can be known or unknown. A correction can be applied to compensate for a known systematic measurement error.
NOTE 3 Systematic measurement error equals measurement error minus random measurement error.

1,测量误差
测量误差是测量数值减去参考价值数值
注1)的测量误差的概念可用于以下两个方面:
a)出现单一参考数值是指存在如下情形:如果误差是根据计量标准进行校准的且测量数值存在可忽略不计的测量不确定性,或者给出常规数值,在这种情况下测量误差是已知的。
b)假定测量误差由一个非常规的真数值或处于可忽略不计范围的一套真数值所表示,在这种情况下,测量误差是不可知的。
注2:测量误差不应与生产中发生的差错或过失相混淆。
2、random measurement error
component of measurement error that in replicate measurements varies in an unpredictable manner
NOTE 1 A reference quantity value for a random measurement error is the average that would ensue from an infinite number of replicate measurements of the same measurand.
NOTE 2 Random measurement errors of a set of replicate measurements form a distribution that can be summarized by its expectation, which is generally assumed to be zero, and its variance.
NOTE 3 Random measurement error equals measurement error minus systematic measurement error.
2,随机测量误差
测量误差分量在重复测量中会以不可预知的方式发生变化。
注1:一个随机测量误差的参考数值是一个平均数值,它会因对一个相同的被测量的无限次的重复测量而产生。
注2:一套重复测量的随机测量误差会形成一种分布区间,它可以通过它的期望值汇总,通常假定其期望值为零,并且其方差也为零。
注3:随机测量误差等于测量误差减去系统测量误差。
3、systematic measurement error
component of measurement error that in replicate measurements remains constant or varies in a predictable manner
NOTE 1 A reference quantity value for a systematic measurement error is a true quantity value, or a measured quantity value of a measurement standard of negligible measurement uncertainty, or a conventional quantity value.
NOTE 2 Systematic measurement error, and its causes, can be known or unknown. A correction can be applied to compensate for a known systematic measurement error.
NOTE 3 Systematic measurement error equals measurement error minus random measurement error.
3,系统的测量误差
测量误差分量在重复测量中保持不变或以可预测的方式变动。
注1:一个系统测量误差的参考数值是一个真数值,或者说是一个根据测量标准可忽略测量不确定性的已测数值,或是一个常规数值。
注2:系统的测量误差及其原因,可以是已知或未知的。可使用校正来弥补已知的系统测量误差。
注3:系统测量误差等于测量误差减去随机测量误差。
