摘要: 不确定度是评价测量结果准确可靠,评估实验室检测能力的重要指标。采用科学可靠的方法进行不确定度分析十分必要。蒙特卡洛法是实现概率分布传播的一种数值方法,适用范围比GUM法更加广泛。采用蒙特卡洛法对吸油烟机全压效率不确定度进行评定,给出了标准不确定度和包含区间,并与传统的GUM法不确定度评定结果进行了分析比较。

关键词: 吸油烟机, 全压效率, 不确定度, 蒙特卡洛法, GUM法

Abstract: Uncertainty is an important index to evaluate the reliability of measurement results and evaluate laboratory testing ability. It is necessary to use scientific and reliable method to analyze uncertainty. Monte Carlo method is a numerical method to realize the propagation of probability distribution. It is more widely used than GUM method. Monte Carlo method is used to evaluate the uncertainty of the total pressure efficiency of the range hood. The standard uncertainty and the inclusion interval are given, and the results are compared with the traditional GUM method.

Key words: Range hood, Total pressure efficiency, Uncertainty, Monte Carlo method, GUM method
