基于联系数的钢筋抗拉强度测量不确定度评定新方法

A New Method of Evaluation of Measurement Uncertainty for Steel Bar Tensile Strength Based on Connection Number

钢筋抗拉强度的不确定度包括:钢筋直径的不确定度分量,拉力的不确定度分量,检测结果重复性引入的不确定度分量,数据修约的不确定度分量等等,因此,测量不确定度是与测量数据相联系的,联系数是处理不确定性问题的一种系统数学理论,可以用联系数来表示测量不确定度,为此,提出一种基于联系数的钢筋抗拉强度测量不确定度评定的新方法.

Uncertainty of tensile strength of steel bar includes： uncertainty component of diamond of steel bar. Uncertainty component of tensile force, uncertainty component of repeatability of results of measurements. Data recondition and so on. Therefore, Measurement uncertainty is connected with measuring data. Connection number is a systematic theory to deal with the problem of uncertainty, Measurement uncertainty can be expressed by connection number. The paper presents a new method of evaluation of measurement uncertainty for steel bar tensile strength based on connection number.
