| 中文摘要: |
| 利用top down控制图评定库伦法测定煤中全硫的不确定度，通过对标准煤品的多次测试结果计算正态统计量，并对数据的正态性和独立性作判别，在确保数据随机排列的基础上，计算期间精密度标准差，最终得到该项目的不确定度评定结果。 |
| 英文摘要: |
| A top down control chart was used to evaluate the uncertainty of total sulfur in coal by Kulun determination. With the calculation of normal statistics through repeated testing results of standard coal and the judgement for the normality and independence of data, the uncertainty evaluation results were obtained on the basis of ensuring the randomly arranged data, and calculating the standard deviations. |
