摘要
简要介绍了用JSJ-Ⅱ型检验仪,校验水准仪视准线误差测量不确定度的方法,给出了i角测量数学模型和不确定度传播率的计算公式,讨论了标准不确定度评定、合成标准不确定度,比较了级别不同被校水准仪的不确定度测量结果,得出了该方法满足JJG 425—2003水准仪检定规程要求的结论。
The author briefly introduced JSJ-Ⅱ check meter and methods of uncertainty of measurement error of collimation line of water level,and obtained calculation formula of Ⅰ angel mathematical models and pass-on rate of uncertainty.Then,the author discussed assessment of standard uncertainty and combined standard,and compared results of uncertainty of measurement of different level.Finally,the author obtained conclusion of hitting the spot of verification regulation of JJG 425—2003 water level.
