固定地点计量比对中传递标准稳定性评估研究——以大型衡器计量比对为例

Study on the Stability Evaluation of Transfer Standard in Fixed Location Metrological Comparison——Take the Metrological Comparison of Large Weighing Instrument as an Example

为了考察计量量值的一致性,采用实验室之间的计量比对是有效的方法,大量测量设备因体积大,不易运输,其计量比对通常采用固定地点进行计量比对的方法进行,比对中传递标准的稳定性对计量比对结果的可靠性会带来较大的影响,通过对稳定性不同方法研究评估,以及实验验证结果表明,研究提出了几种传递标准稳定性评估方法,其稳定性对结果的影响有较好的一致性。

In order to investigate the consistency of measurement values,it is an effective method to use the measurement comparison between laboratories.A large number of measuring equipment is difficult to transport due to its large volume.The measurement ratio is usually carried out by the method of measuring comparison at fixed place.The stability of the transfer standard in the comparison will have a great impact on the reliability of the measurement comparison results.The results of different methods of stability research and test show that several transfer criteria stability evaluation methods are proposed,and the stability of the methods has a good consistency on the results.
