摘　　要：本文建立状态转移比与成员属于等级的时间有关的等级结构的动力学模型,并利用正半群理论得到解的渐近性态。In this paper, a dynamic model of grade structure is deduced in which the transfer ratios are relevant to the time that a member belongs to a grade. By the theory of positive semigroups the asymptotic behavior of its solution is obtained.

关 键 词：等级结构 发展方程 渐近性态 动力学模型 解
