摘要：

We investigate the global behavior for a population whose members are divided into two classes: juveniles and adults, with mortalities age- and density-dependent. Laplace transforms are used to examine the asymptotic dynamics of age profiles, which describes completely the evolution process of the nonlinear population system. Our result can be viewed as a generalization of Sharp-Lotka theorem in some nonlinear situations.
