一、基本概念分析示值误差是用于评价测量仪器特性的,而测量结果不确定度是用于评价测量结果质量的,二者存在很大区别,但在反映测量结果质量方面,又有共性之处。示值误差是指测量仪器的示值与对应输入量的真值之差。其误差数值有正、有负,一般通过实验获得。示值误差可对测量结 First, the basic concept of analysis Indication error is used to evaluate the characteristics of measuring instruments, and measurement uncertainty is used to evaluate the quality of measurement results, there is a big difference between the two, but in reflecting the quality of measurement results, there are common Where. The indication error is the difference between the indication of the measuring instrument and the true value of the corresponding input. The error values ​​have positive and negative, generally obtained through experiments. Indication error can be measured
