摘要:

本文采用随机抽样推测法对液化石油气泄放过程的参数不确定性进行了处理，确定了液化石油气瞬间泄放是等速泄放过程。并对连续形成的蒸气云爆炸和沸腾液体扩展蒸气爆炸的后果进行了分析，定量估算了液化石油气槽车两次爆炸事故后果的影响程度。

Abstract:

This paper discussed the parameter uncertainties of the LPG leaking processes by means of the random sampling guesswork method. It was proved that the LPG immediate leakage was a kind of uniform leakage. And the analysis of result that caused from the con
