摘　　要：提出了一个基于简化动力学模型的大气层核爆炸烟云与放射性沉降模型,考虑了烟云稳定前放射性颗粒的沉降过程,同时考虑了早期烟云宽度随时间的变化,在烟云稳定后采用了大尺度相对扩散理论。与美国四次核试验数据以及DELFIC模型比较表明,本模型基本是合理的、可用的。A simple dynamic rising nuclear cloud based model for atmospheric nuclear explosion radioactive prediction was presented. The deposition of particles and initial cloud radius changing with time before the cloud stablization was considered. Large-scale relative diffusion theory was used after cloud stablization. The model was considered reasonable and dependable in comparision with four U. S. nuclear test cases and DELFIC model results.
