摘要
根据环境监测的要求,中国石油集团安全环保技术研究院实验室在出具数据时要对测量结果进行测量不确定度评定。用实例建立了分光光度法测定水样品中挥发酚的合成标准不确定度的数学模式,它由质量的标准测量不确定度和体积的标准测量不确定度组成;并对这两部分标准不确定度的分量作了详尽的分析和计算。得出测量扩展不确定度结果。
According to the requirement of environmental monitoring,the measurement uncertainty should be evaluated when giving data by Environmental Monitoring Center,CNPC. We established a mathematical uncertainty model of volatile phenol in water sample based on actual examples by spectrophotometry,which composed by quality and volume measurement uncertainty. The quality and volume uncertainties were analyzed and calculated in detail,and the value of expanding measurement uncertainty was obtained.
