摘要
采用华格森公司生产的HGAS-OEB便携式氧分析仪测定工业氧纯度,与标准法(GB\T3863-2008)进行对照实验,再应用数理统计方法对结果加以分析,证明仪器法和标准法的数据无显著性差异(显著性水平为0.05,样本数为5),且两者具有相似的精密度和准确度。
We can determine industrial oxygen purity by using the HGAS-OEB portable oxygen analyzer made in Huage Sen Company. During the test, we use the standard method （GB/T3863-2008） to control experiment, and then apply the mathematical statistical methods to analyze the results, to prove that instrumental method has no significant difference with the standard method at the result of data （significance level of 0.05, the number of samples is 5）, and both have similar precision and accuracy.
