摘要
采用梅特勒公司生产的DE40密度仪测定密度,与标准法(GB338-92)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7),且两者具有相似的精密度和准确度。
To measure density with DF40 density meter produced by Mettler Toledo Instruments Co. Ltd, contrast with standard method (GB4472), then analyze the results by mathematical statistics. It is proved that there is no noticeable difference between the instrument method and the standard method (significance level is 0.05 and the number of sample is 7), so the two methods have similar precision and accuracy.
