摘　　要：为论证气体相对蒸气密度在工程实际中具有的重大应用价值,采用理论推导的方法,对气体相对蒸气密度的计算进行研究.研究结果表明:利用重大危险源辨识方法,采用《危险化学品安全技术全书(第二版)》判定结果"氧气球罐区构成危险化学品重大危险源",而采用该研究方法则"未构成危险化学品重大危险源".证实了《危险化学品安全技术全书》等相关技术书籍与实际计算数值存在不一致现象.该成果对不同状态下的气体相对蒸气密度研究具有理论价值,对压力球罐等重大危险源辨识具有参考价值.In order to demonstrate the application value of the relative vapor density of gas in engineering practice, this paper studied the relative vapor density of gas with the method of theoretical derivation. The results show that the area of oxygen spherical tank is a dangerous chemicals major hazards with the use of the major hazard identification methods, and the decision results in the hazardous chemical materials safety technology encyclopedia （Second Edition）, but it is not a dangerous chemical major hazards adopting the methodology of this research. This paper confirms the non-conformance with the numerical value of hazardous chemical materials safety technology encyclopedia and other related technical books and the actual calculation results. This study has theoretical value in the study of gas with different conditions of the relative vapor density, and has reference value in identifying the major hazard of pressure spherical tank.
