随着科学技术和社会生产的发展,对测量数据的准确性和可靠性要求越来越高。由于各种环境、仪器设备以及人员主观性的影响,任何测量都不可能绝对准确。因此,在测量过程和最终判断时,都必须考虑测量的不确定度,其大小决定了测量结果的可信度。不确定度越小,测量结果质量越高,可信度越高。而由于特种设备检验工作的特殊性,需要可信度高的检测数据,尽可
With the development of science and technology and social production, the accuracy and reliability of measurement data are increasingly demanding. Due to the subjective influence of various environments, instruments and personnel, no measurement can be absolutely accurate. Therefore, in the measurement process and the final judgment, we must consider the uncertainty of the measurement, the size of which determines the credibility of the measurement results. The smaller the uncertainty, the higher the quality of the measurement, the higher the credibility. And because of the special equipment inspection work, the need for high reliability test data, all
