摘要
对矿用风速表对不确定度评定进行测量所采用的基本模式和常用方法进行基本阐释,并进行评定数学模型的建立,不确定度来源的分析和测量等的介绍,同时还要分别简述不确定度的分量、各标准不确定度的分量、自由度、有效自由度、合成标准的不确定度、扩展不确定度等参数的计算流程,最后指出相应步骤中的重点问题。
This paper mainly aims to the speed mine table for evaluation of uncertainty of measurements are made using the basic mode and common methods of interpretation of the basic, and the establishment of mathematical model of evaluation, uncertainty sources of analysis and measurement is introduced,even at the same time,it describes briefly the uncertainty components,the standard uncertain？ty components,degree of freedom,the available degrees of freedom,the standard synthetic uncertain degree,the expanded uncertainty of the parameters in the calculation process. Finally,it pointed out that key problems corresponding step.
