全文以混凝土立方体抗压强度检测数据为例,以逐步计算的方法,得出平均值,标准差,以及最终不确定度,给出传统建筑材料常用不确定度的计算全过程,从而解决试验室初级人员对不确定度难以掌握的难题,有利于不确定度在常规试验检测报告中的应用以及对本实验室检测水平的评价。 The full text takes the compressive strength test data of concrete cubes as an example to calculate the average value, standard deviation and final uncertainty with the method of stepwise calculation, and gives the calculation of the common uncertainty of the traditional building materials to solve the problem of laboratory Junior staff difficult to grasp the uncertainty of the problem, is conducive to the application of uncertainty in routine test reports and evaluation of the level of laboratory testing.
