摘　　要：油气爆炸极限是油料安全监测最重要的参数之一,在环境温度、湿度、压力等因素的影响下均会发生变化。通过对不同环境温度中汽油蒸气的爆炸下限进行实验研究,得到环境温度对汽油蒸气爆炸下限的影响效果。研究结果表明,随着环境温度的升高,爆炸下限降低,环境温度与爆炸下限之间的关系呈非线性。根据实验数据和理论分析,建立了环境温度-爆炸下限拟合计算式。该式结构简单,在实验温度范围内具有较高拟合度,扩展温度范围仍有一定的参考价值。The explosive limit of gasoline-air mixture is one of the most important parameters in safety monitoring, and it var- ies with the influence of environmental temperature, humidity, pressure and other factors. This paper presents the experimental study on lower explosive limit of gasoline-air mixture at different temperatures. Research results show that, with the rise of environ- mental temperature, lower explosive limit drops. However, the function of environmental temperature with explosive limit is non-lin- ear. According to the experimental data and theoretical analysis, the fitting formula to express the relationship between temperature and lower explosive limit is established. The formula, which has simple structure, can fit the relationship well in the experimental temperature range, and its fitting result still has a high reference value in extended temperature range.
