| 中文摘要: |
| 分析天然橡胶（NR）生胶杂质含量检测的精密度和不确定度。结果表明：NR生胶杂质质量分数检测的精密度符合GB/T 8086—2008要求，不确定度可表示为0.000 927±0.000 098，置信水平约为95%，检测结果近似服从正态分布；NR生胶杂质质量分数的检测结果一致性好，分散性在可接受范围内。 |
| 英文摘要: |
| The precision and uncertainty of natural rubber impurity content determination was analyzed. The results showed that，the precision of the impurity mass fraction met the requirements of GB/T 8086— 2008，the uncertainty could be expressed as 0.000 927±0.000 098，and the confidence level was about 95%. The tested data of impurity mass fraction obeyed normal distribution，which had good consistency and acceptable variation. |
