| 中文摘要: |
| 根据测量不确定度的原理,分析了硫氰酸铵容量法中水泥的氯离子含量检测的各分项不确定度影响。并从重复性、称样、滴定消耗体积等因素对测量水泥中氯离子含量的不确定度进行评定,从而计算不确定度,以及对实验操作进行规范。 |
| 英文摘要: |
| According to the principle of measurement uncertainty, the influence of uncertainty of each item of the chloride ion content detection of cement in ammonium thiocyanate volumetric method is analyzed. And from the repeatability, sample weighing, titration consumption volume and other factors to assess the uncertainty of measuring chloride ion content in cement, so as to calculate the uncertainty and standardize the experimental operation. |
