【摘要】 对入池酒醅酸度的整个测定过程进行不确定度的来源评定与量化,找出引起不确定度的主要因素,最终评定影响测定结果的主要因素有样品的重复性测定、滴定管、量筒量取浸泡试样的蒸馏水体积、氢氧化钠标准滴定溶液、吸取滤液的分度吸管。本次入池酒醅度测定的扩展不确定度为0.1034mL/g。更多还原

【Abstract】 The assessment of the source of uncertainty and quantification of the acidity of the wine into the pool to identify the main factors that cause uncertainty, the final assessment of the main factors affecting the determination of the results of the sample repeatability, burettes, measuring the amount of cylinder Soak the distilled water volume of the sample, sodium hydroxide standard titration solution, draw the filtrate indexing pipette. The expansion of the determination of the pool wine uncertainty of 0.1034 mL/g.更多还原
