数字密度计与经典方法测定密度、浓度的比较
A comparison between digital densimeter and classical instruments for the determination of density and concentration
【摘要】 通过数字密度计与经典方法(密度计法,比重瓶法,酒精计法)测定密度、浓度之间的方法、原理与实验数据的对比分析,表明数字密度计较经典方法具有显著的优越性:测定结果精度高,操作简便、快速适用范围广,测定时不受环境温度影响.并用数理统计原理进行数据分析,证实仪器与经典法之分析结果间无显著性差异.
【Abstract】 A comprehensive comparison between digital densimeter and classical instruments for the determination of density and concentration has been made. The result shows that the digital densimeter has the advantages of high precision, simple operation, wide application and is free from the influence of the outer temperature.
