摘要 介绍了随机环境中的两性分枝过程,利用概率母函数之间的关系,推导出此类两性分枝过程的有关性质,同时给出了两类常见随机环境中两性分枝过程灭绝的充分条件. We consider a bisexual branching process in independent and identically distributed random environments. The properties of the bisexual branching processes are obtained by probability generating functions. Sufficient conditions for extinction probability about two usual bisexual branching processes are given.
