摘　　要：综述了稳定性同位素质谱技术,主要包括元素分析-稳定同位素比值质谱法(EAIRMS)和气相色谱-稳定同位素比值质谱法(GC-IRMS),在法庭科学微量物证(包括助燃剂、爆炸物、油漆、土壤、纤维、胶带、塑料以及纸张等)分析中应用的研究进展,主要涉及物证的样品区分、产地溯源和同一认定等(引用文献54篇)。Research progress of the application of stable isotope mass spectrometry techniques[including elemental analysis-stable isotope ratio mass spectrometry(EA-IRMS)and gas chromatography-stable isotope ratio mass spectrometry(GC-IRMS)]in the analysis of trace material evidence(i.e.,combustion improver,explosive,paint,soil,fiber,tape,plastic,paper,etc.)in forensic science,was reviewed.Main applications involved the sample identification,origin traceability and identical authentication for trace material evidence(54references cited).
