摘　　要：对比点源模型和半球模型选取蒸气云爆炸(UVCE)模型,对比火球模型和热辐射伤害模型选取沸腾液体扩展蒸气爆炸(BLEVE)模型,对比研究LNG和LPG泄漏后的蒸气云爆炸和沸腾液体扩展蒸气爆炸的危害。如事故现场的障碍物(受限空间)较多,火焰容易加速使爆燃向爆轰发展。无论是UVCE事故还是BLEVE事故,LPG的伤害范围均大于LNG。The UVCE model was selected by comparing the point source model with hemisphere model, the BLEVE model was selected by comparing the fireball model and heat radiation injury model, and the UVCE and BLEVE accidents of LNG and LPG were studied.The fire would be celebrated and the deflagration had the trend to be detonation when there were obstacles in the acci- dent. The UVCE accident and BELEVE accident of LPG have big- ger alert range than that of LPG.
