| 摘 要： | 本文选用高斯模型对放射性气溶胶扩散特性进行了模拟研究,分析了影响气溶胶扩散的主要几何参数和气象因素,探求了放射性污染物在地面上的浓度分布,最大浓度位置以及安全范围的划分等问题.模拟研究结果与相关文献相一致,证明了高斯扩散模型对此类扩散模拟的合理性和有效性;这为全面了解放射性气溶胶扩散的特性、对快速、有效地处置核事故具有指导意义.

| Abstract: | In this paper,the radioactive aerosol diffusion characteristics were simulated using Gaussian model.The major geometric parameters and meteorological factors affecting the aerosol diffusion were analyzed,and such questions as concentration distributions,the maximum concentration position of the radioactive pollutants and safety range of division were studied.The simulation results were consistent with the ones in related documents,which showed the rationality and validity of Gaussian model and can be guidance to fire army in quickly and effectively disposing of the similar nuclear accidents. |
