摘要:: 为了给船舶舱底水溢油鉴别提供一种实用有效的分析手段，在3个船舶舱底水中分别取可疑溢油油样US、1S、2S，采用气相色谱质谱法（GC-MS）对3个可疑油样和一个模拟溢油油样EUS进行了测定数据分析，通过正构烷烃相对浓度分析、诊断比值分析和模糊诊断分析，最终确定了溢油源为US．实验结果表明，采用GC-MS测定的实验数据和分析方法合理，可为船舶溢油鉴别提供帮助．

Abstract:: In observation of application of the gas chromatography-mass spectrography（GC-MS）to the source identification of ship bilge water,analyses of the data were carried out on three suspected oil spill samples（US,1S,2S）from ship bilge water and one simulated oil spill sample(EUS).Measurements were conducted on such aspects as the relative concentration of n-alkanes,diagnostic ratios,similarity matrix of relative concentration as well as the clustering analysis diagram.It shows that the results from GC-MS could provide reliable information for the identification of ship oil spill.Conclusions were drawn that the GC-MS method is applicable to identifying the source of the ship bilge water.
