摘　　要：对 18种具有代表性的喷气燃料油样进行了硫化合物含量分析及硫化合物与银片腐蚀关系研究。通过相关系数计算和统计分析表明 ,银片腐蚀结果受元素硫含量的影响非常显著 ,二硫化物硫、腐蚀性硫的影响次之 ;不合格喷气燃料腐蚀性硫含量均在 30× 10 - 6 (ω)以上 ,含有一定量元素硫 (>1.0× 10 - 6 ) ,明显区别于合格喷气燃料。Sulfide content in eighteen representative of samples of jet fuels were determined,and the relationship between sulfides and jet fuels silver strip corrosion were studied. By correlation coefficient calculating and statistics analyzing, it was shown that the rating of silver strip corrosion test was remarkably affected by elemental sulfur, and secondly by disulfide and other corrosive sulfur. Corrosive sulfur content in unqualified jet fuels is above 30μg/g, and unqualified jet fuels have some elemental sulfur(>1.0μg/g), which was distinguished clearly from qualified fuels.
