摘　　要：总结归纳了有毒介质泄漏扩散过程特点及泄露量计算的模型。以乌鲁木齐石化尿素生产装置为例进行有毒介质泄露扩散分析,在此基础上运用计算机模拟软件,模拟有毒介质扩散的过程,给出了定量化的评价结果。依据此例,将有毒介质泄露扩散模型引入安全评价的体系中,丰富了安全评价的体系内容,增加了安全评价定量化评价的方式。The leakage quantity calculation model and the characteristics of the poisonous medium leakage and diffusion are summarized and described. We set up the urea unit in Urumchi Petro-chemical Company as the study case, and do the analysis of Poisonous medium leakage and diffusion. On this basis, we do the related simulation by the software, simulating the process of the Poisonous medium leakage and diffusion, and get the quantitative evaluation results. Thus, we introduce the Poisonous medium leakage and diffusion model into the system of safety evaluation, enriching the content of the system and increasing the quantitative evaluation method.
