测量不确定度是评定测量水平的指标,是判定测量结果质量的依据。我们依据JJF 1059-1999《测量不确定度评定与表示》[1],结合实际工作,利用两种噪声测量仪器对某企业油泵厂房内油泵的噪声强度进行了测定,并对其测量不确定度进行了对比分析评定。
Uncertainty in measurement is the measure of the level of measurement of indicators is to determine the quality of measurement basis. According to JJF 1059-1999 “Evaluation and Expression of Measurement Uncertainty” [1], combined with the actual work, the use of two kinds of noise measuring instruments to measure the noise intensity of an oil pump plant in an enterprise, and its measurement uncertainty Conducted a comparative analysis of assessment.
