摘　　要：介绍了国外经典的核爆炸放射性沉降模式，包含了DELFIC、WSEG系列、KDFOC系列、SEER系列、DNAF系列和EM-1。同时列举了各种模式在主要物理过程中的区别，包括了云的初始化、粒子分布、沉降机制，放射性活度和剂量率的转化、放射性衰变和传输过程。最后简述了目前核爆炸放射性沉降模式研究的发展趋势。Some foreign classic nuclear explosion radioactivity deposition patterns are reviewed, including DELFIC, WSEG series, KDFOC series, SEER series, DNAF series and EM-1. It also shows their specific characters and compares the difference among those patterns in main deposition physical process, including initial cloud, particle distributions, fall mechanics, total activity and activity to dose rate conversion, decay and transport. Finally, current development trend of nuclear explosion radioactivity fallout patterns is introduced.
