【摘要】The characters of some numerical models which describe discharging dis persion process of flammable or toxic gases have been analyzed. The models inclu de Gaussian plume/puff model, Gaussian plume trajectory model, BM model, Sutton model and FEM3 model. Gaussian plume/puff and Gaussian plume trajectory models u sed abroad have been introduced emphatically. Aiming at the complication of the di spersion process,such as weather conditions and landform situation which influen ce the d iffusion process of flammable or toxic gases have been analyzed in detail, and s ome countermeasures have been put forward to ascertain some uncertain parameters .%分析了描述易燃易爆及有毒有害气体泄漏扩散过程的数学模型，包括Gaussian模型、Gaussian轨迹烟云模型、BM模型、Sutton模型及FEM3模型。重点介绍了目前广泛使用的Ga ussian模型及Gaussian轨迹烟云模型。针对事故泄漏扩散过程的复杂性，详细讨论了气象条件及地形条件对危险性物质泄漏扩散过程的影响，此外还对不确定参数的选取进行了探讨。 【总页数】4页(19-22)
