水泥浆稠度仪水流时间的量值传递及影响量的分析与研究

介绍了水泥浆稠度仪的工作原理和用途,建立了水泥浆稠度仪水流时间校准结果的测量模型,分析了各不确定度分量主要来源。结合测量实例具体数据,对其合成不确定度进行分析评定,对各不确定度分量进行计算并得出合成不确定度和扩展不确定度,最终可得出该项目的校准测量能力,为我国建筑和交通等行业提供技术支撑。

This paper introduces the working principle and application of mud consistency meter f low time,establishes the measurement model of the calibration results of mud consistency meter f low time,analyzes the main sources of each uncertainty component,analyzes and evaluates the synthetic uncertainty combined with the concrete data of the measurement example,calculates each uncertainty component,obtains the synthetic uncertainty and extended uncertainty.Finally,the calibration and measurement ability of the project can be obtained.Overall,this paper can provide strong technical support for construction,transportation and other industries in our country.
