摘　　要：介绍了一类年龄结构相关的两性分支模型,这类模型也可以看做一类特殊的非线性Leslie人口模型.在一夫多妻配对函数条件下,给出了此模型以概率1灭绝的一个充要条件.One class of age-structured bisexual branching processes is introduced, this model can be modified nonlinear Leslie model. Under promiscuous mating function, a criterion to identify whether the admits ultimate extinct with probability one is obtained. seen as process

关 键 词：两性分支过程 Leslie矩阵 一夫多妻制配对函数 灭绝概率
