摘　　要：依据标准方法石油产品运动黏度测定法和动力黏度计算法对车用柴油运动黏度进行分析。本文建立了运动黏度不确定度的数学模型,分析了不确定的来源,讨论了影响运动黏度测量不确定的各种因素,计算了相对标准不确定度分量、合成标准不确定度和扩展不确定度。结果表明,影响测量不确定度的主要因素为温度。Based on the standard method of the determination of kinematic viscosity and calculation dynamic viscosity of petroleum products to analyze the kinematic viscosity of automobile diesel fuels . The mathematical model of uncertainty in kinematic viscosity was established, the sources of uncertainty were analyzed, some factors influencing the uncertainty of the test results of kinematic viscosity were discussed, the components of related standard uncertainty, combined standard uncertainty, and expanded uncertainty were calculated. The results showed that determination uncertainty was mainly due to comperature.
