提出了液体推进剂火箭爆炸后残余推进剂蒸发形成的有毒气体在大气中扩散的解析模型， 并数值模拟了地面有毒气体浓度场在不同的环境、天气情况下的分布情况及环境参数对毒气扩散过程影响的分析， 能为工程应用提供实用的数据。
An analytical model of the diffusion of toxic gases formed by the evaporation of residual propellants after the liquid propellant rocket explosion is presented. The distribution of toxic gas concentration fields in different environments and weather conditions is numerically simulated, and the effects of environmental parameters on the diffusion of toxic gases Analysis of process impact can provide practical data for engineering applications.
