摘　　要：近年来,有毒气体泄漏扩散的案例时常发生,而且每次发生的事故都会引起非常严重的人员伤亡和环境污染,带来巨大的财产损失。为了保护环境、减少人员伤害和经济损失,本文应用Matlab模拟有毒气体泄漏扩散的过程,建立有毒气体泄漏过程的扩散浓度与扩散距离的相关函数,并对影响毒气泄漏扩散的大气稳定度、风速、地表粗糙程度等参数进行敏感性分析。In recent years, there have been frequent cases of toxic gas leakage and diffusion, and each accident has caused very serious casualties and environmental pollution, resulting in huge property losses. In order to protect the environment, reduce human jnjury and economic losses, this paper uses Matlab to simulate the process of leakage and diffusion of toxic gases, and establishes the correlation function of the diffusion concentration and diffusion distance of the toxic gas leakage process. Sensitivity analysis was performed on parameters such as atmospheric stability, wind speed, and surface roughness affecting the diffusion of toxic gases.
