目的：了解某型坦克作业条件下驾驶室内挥发性有机物的污染状况，为制定防治措施提供科学依据。方法：应用气相色谱－质谱联用技术（ＧＣ－ＭＳ）对某型坦克在单纯行进、行进打炮、停车打炮等工作状态下驾驶室内以及废气排放口的挥发性有机物（ＶＯＣｓ）进行了全谱分析。结果：共检出１３４种污染物质，包括脂肪烃类、单环芳烃类、多环芳烃类以及有机酸、碱、酯、醛、酮、杂环化合物等。结论：实验结果表明这些物质主要来源于油类蒸气、废气倒灌和射击气体等，其联合作用可能是影响指战员战斗力和作战能力的重要原因
Objective: To understand the pollution status of volatile organic compounds (VOCs) in the cab of a certain type of tank and to provide a scientific basis for making prevention and control measures. Methods: The GC-MS was used to conduct a full-spectrum analysis of volatile organic compounds (VOCs) in a cab and an exhaust vent under certain operating conditions such as traveling alone, traveling gun and parking gun, etc. . Results: A total of 134 pollutants were identified, including aliphatic hydrocarbons, monocyclic aromatic hydrocarbons, polycyclic aromatic hydrocarbons and organic acids, bases, esters, aldehydes, ketones, heterocyclic compounds and so on. CONCLUSIONS: The experimental results show that these substances are mainly derived from oil vapors, exhaust gas intrusion and shooting gases, and their combined effects may be important factors that affect the combat effectiveness and operational capability of officers and men
