The lower explosive limit of mixture will decrease with the increase of gas concentration; 混合物的爆炸下限(LEL)浓度随瓦斯浓度的增加而降低;
The conflicting problem of flash point and lower explosive limit as a criterion of hazard is studied in this paper. 文章就闪点与爆炸下限(LEL)作为危险性判据相抵触的问题进行了探讨。
According to the range of lower explosive concentration limit, methods for how to set up warning region were research. 通过分析氨气扩散后爆炸浓度下限范围,探讨了如何设置警戒区的方法。
