| 摘 要： | 通过对时间资源有限情况下的流域事故性污染源最优搜索策略的研究,从搜索目标状态和搜索资源能力两个方面分析了影响流域事故性污染源最优搜索的因素,根据最优搜索理论,构建了流域事故性污染源最优搜索模型体系,在确定了目标初始概率分布、探测函数形式和时间资源上限以后,即可计算出最优的搜索资源分配。

| Abstract: | In the condition of limited time and efforts,based on the optimal search strategy,factors that affected optimal search of accidental pollution source in drainage area were analyzed in terms of search target state and search resource efforts.According to optimal search theory,a model system for optimal search of drainage area accidental pollution source was established.Based on which the optimal distributing for search efforts can be calculated immediately once target initial possibility distribution,exploration function format and upper limit of effort was confirmed. |
