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.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 sam-ples （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.
