摘　　要：冰点是表征航空燃料低温使用性能的重要指标。常规冰点测定方法操作步骤复杂，测定时间长，影响航空燃料质量检测效率。基于光散射原理，将温度传感和光电检测技术应用于航空燃料冰点测定，利用燃料结晶对光散射和透射的影响，实现航空燃料冰点快速测定。该方法操作简单快速，检测1个油样用时少于15min，大幅提高了冰点检测效率；试样体积仅需2mL，有利于试验环境保护；测定结果重复性好，与标准方法GB／T2430-2008具有良好的相关性。Freezing point is an important quality indicator to characterize the performance of aviation fuel in low temperature. Conventional determination of freezing point is a complex procedure which takes long time for measuring so that the testing efficiency of aviation fuel quality is reduced. On the principle of light scattering techniques, the temperature sensing and photo-electric detection technologies are used in the determination of aviation fuel freezing point. The interaction between the crystallization light scattering and transmission in fuel is used to achieve rapid determination. The results show that the operation method is simple and fast. It highly increases detecting efficiency of freezing point. It spends less than 15 minutes to detect one oil sample and the experimental efficiency is greatly enhanced. Test specimen requires volume of oil only 2 mL, which is helpful to protect the environment. Measurement results are repeatable and have well correlation with the standard method in GB/T 2430 -2008.
