摘要
论述了长度计量仪器示值误差表达式±(A+B·L)和准确度表达式(A+B·L)及其区别。给出了系数A和B的推求方法,并讨论了表达式与《GB1800—79公差配合》中标准公差的匹配关系。
The formulas'±(A+BL)' and '(A+BL)' are used to express indicating error and accuracy of dimensional metrology instrument.In this paper their meaning and the method which is used to evaluate constants 'A' and 'B' in the formulas are discussed. The formulas suitability for standard tolerance in 'GB1800-79 Tolerance and Fit' are also discussed.
