摘　　要：航空煤油中含有水分,会使其冰点提高,危及飞行安全,需进行燃油结冰试验。准确测量航空煤油的水分是结冰试验的基础。本文采用卡尔费休滴定法测试不同温度饱和状态航空煤油的水分,获得不同温度下饱和状态航空煤油的含水量,并分析了影响实验结果准确性的因素。The freezing temperature of aviation kerosene will increase when there is water in it,which will endanger the flight safety.So,the fuel icing test is necessary.How to measure the moisture content of aviation kerosene accurately is the basement of the fuel icing test.The moisture content of saturated aviation kerosene in different temperature is achieved in the test.The influencing factors which influence the accurate of the test result are also analyzed.

关 键 词：卡尔费休滴定法 航空煤油 水分含量
