摘　　要：[目的]建立烘干法测定蔗渣水分不确定度评定的方法。[方法]通过分析不确定度的主要来源,建立数学模型,确定合成不确定度和扩展不确定度,得到该检测方法的测量不确定度评定方法。[结果]研究表明,烘干法测定蔗渣水分不确定度评定的方法中由温度引入的不确定度大。通过统计分析得出,烘干法测定蔗渣水分的测量扩展不确定度为0.915 1%。[结论]研究可为评定蔗渣水分测量不确定度提供参考依据。[Objective] To establish oven drying method to determine uncertainty in water content of bagasse.[Method] Through analyzing main sources of uncertainty,establishing mathematics model,synthesis and expanding uncertainty was determined,the evaluation method for uncertainty determination was obtained.[Result] The results showed that the uncertainty of temperature is bigger,and through the statistic analysis,expending uncertainly water content of bagasse with oven drying method is 0.915 1%.[Conclusion] The study can provide reference basis for determining uncertainty of water content of bagasse.
