摘　　要：目的:对不同校准方式下修正值的计算公式加以比较总结,研究其中规律。方法:对校准工作中的标准器和被评定对象分别按照实物量具和指示式测量仪器进行分类,对不同校准方式下的修正值计算方法分别进行推导。结果:对于使用实物量具校准实物量具的校准方式,被评定仪器的修正值=比较装置测量被评定仪器时的示值-比较装置测量标准器时的示值+标准器的修正值;对于另外三种校准方式,被评定仪器的修正值=标准器的示值-被评定仪器的示值+标准器的修正值。结论:使用实物量具校准实物量具的校准方式下的修正值计算公式不同于其他校准方式下修正值计算公式。Aims: To study the regulation of correction value calculating methods in different calibration types. Methods: The standards and the calibrated instruments were classified into the material measure and the indicating measuring instrument, respectively. The correction value calculating methods in different calibration types were derived. Results: As for the calibration type of calibrating material measure using material measure, the correction value of the calibrated instrument was the indication of comparison instrument measuring the calibrated instrument minus the indication of comparison instrument measuring the standard, plus the correction value of the standard. As for other calibration types, the correction value of the calibrated instrument was the indication of the standard minus the indication of the calibrated instrument, plus the correction value of the standard. Conclusions: The correction value calculating method in calibrating material measure using material measure is different from that in other calibration types.
