温度类计量标准检定或校准结果重复性试验方法探讨
|
摘要
由于温度一直处于波动状态,即使当温度已趋于稳定,它仍然会在某一温度值附近存在微小波动,所以要想得到确定的测量值非常困难。针对温度这一特性,研究温度类计量标准的检定或校准结果的重复性试验,以确保测量结果更加准确可靠。在阐述检定或校准结果重复性含义的基础上,分析温度类计量标准检定或校准结果的重复性特点。针对传统重复性试验方法的不足,提出改进方法,通过2种方法的实例比较,分析单次试验标准偏差值相差较大的具体原因。结合其他温度类计量器具的特点,提出改进方法的适用场合。
Temperature always fluctuates. Even when a temperature becomes stable, it still slightly fluctuates around a certain temperature value. Therefore,it′s very difficult to obtain a determined temperature value. With a view to such a feature of temperature,the Article studies the repeatability test on the verification and calibration results of temperature-specific measurement criteria,thus guaranteeing that the measurement results become more accurate and reliable. By explaining the meaning of the repeatability of verification and calibration results,the Article analyses the features in the repeatability of verification and calibration results for temperature-specific measurement criteria. In view of the defect of conventional repeatability test methods,it proposes the improvement methods. By comparing the examples from 2 methods,it analyzes the specific reason for a greater difference in deviation values for a single test criterion. In combination of the features in other temperature-specific measuring devices,the Article points out the applicable occasions for the improvement methods.
