纸张透气度测量值的不确定度评定

The Evaluation of Uncertainty for Air Permeability Measurement of Paper

影响纸张透气度检测结果的因素有很多,如环境温湿度、检测仪器、操作人员水平等。由于这些因素对测量值的影响很大,因此需要对测量结果进行不确定度评定。本文以育果袋纸透气度的检测为例,分析纸张透气度测量不确定度的主要来源及评定中的主要影响量,并对检测结果进行不确定度评定,为其它纸张透气度检测结果的不确定度评定提供参考。

There are lots of factors that influence the test result of the air permeability of paper,such as temperature and humidity,testing equipment,skill of the operator,etc. Because the factors have mass affections to the test result,the uncertainty of the impact by other factors should be assessed. In this paper,a test of the air permeability of the fruit cultivating bag paper as an example is done,the main source and the impact to the test of the air permeability of the fruit cultivating bag paper are analyzed,the uncertainty of the test is evaluated,which provides reference for the uncertainty of other air permeability test of paper.
