测量不确定度及其评定

Uncertainty of measurement and evaluation

目前,测量是在科学技术、工农业生产、国内外贸易、工程项目以至日常生活等各个领域中不可缺少的一项工作。测量的目的是确定被测量的量值,测量的质量会直接影响到国家和企业的经营活动。因此,测量不确定度作为衡量测量结果质量的重要指标,对其进行分析研究具有非常重要的意义。本文主要从测量不确定度的发展、定义、来源、分类等方面进行详细的阐述,重点介绍了测量不确定度的评定步骤、评定方法、评定报告等内容。

At present,the measurement is an indispensable work in science and technology,industry,agriculture,domestic and foreign trade,project,daily life and others fields.he purpose of measurement is to determine the value of the tested vector,and the quality of measurement will directly affect the state and enterprise management activities.Hence,It's very important to analyze and research measurement uncertainty which is an important indicator to measure the quality of measurement result.This article mainly expounds the development,definition,origin and classification about the measurement uncertainty,and emphasizes on the uncertainty of measurement assessment steps,evaluation methods,assessment report,etc.
