摘　　要：应用图论原理,建立了一种基于数据库的多分支递次衰变计算方法,编制了计算机程序,用于计算复杂衰变链中各子体放射性强度随时间的变化。设计的递归算法可对衰变路径进行自动搜索和存储,并对路径重复部分进行适当标记,实现了衰变链的程序化计算。Guided by the graph theory, an algorithm based on database technique was deve-loped for calculating the radioactivity of daughters of a decay chain and their variation vs time. By the designed arithmetic of recursion, the pathways of the chain decay are searched and stored automatically. Meanwhile, the repeated part of the pathways are marked and recorded properly, and the decay chains can be calculated by a computer code.
