摘　　要：针对有毒气体储罐泄漏事故,通过对应急救援时间的合理设置,运用半球扩散理论建立数学模型模拟毒气扩散,在充分考虑毒气的物理化学性质、泄漏量、泄漏时间等因素的情况下,使模拟结果具有较高的准确度,为消防部队确定毒气泄漏事故应急处置区域与展开应急救援行动提供理论依据。For leakage accident of toxic gas tank,by a reasonable setting of emergency rescue time,a mathematical model was established to simulate the diffusion course using the hemisphere diffusion theory.In this model,the factors of the physical and chemical properties of gas,leakage,leaking time,etc are considered,which makes the results of simulation have a relative higher accuracy.These will provide scientific theoretical foundation for fire force to delimit the region of leakage disposal and conduct emergency rescue operation.
