摘要
不确定度式说明测量水平的主要指标,是表明测量质量的重要依据。介绍了ASME PTC4-1998中不确定度的计算方法,以某4 t/h蒸汽锅炉的热效率为例,采用正反平衡法计算器热效率,并对结果进行了不确定度比较,结果表明反平衡法热效率结果不确定度较小,符合ASME PTC4-1998中的阐述。
This paper introduced the ASME PTC4-1998 in the computing methods of uncertainty, with a 4t/h steam boiler thermal efficiency as an example, the use of positive and negative balance calculator thermal efficiency, and the results are compared with the uncertainty, the results show that the balance thermal efficiency uncertainty is smaller, with ASME PTC4-1998exposition.
