【摘要】 本文讨论了在齐次Dirichlet边界条件下具有扩散现象的一类广义单种群模型的正定态解．给出了使得严格正解存在的λ的取值范围，并且讨论了当λ充分大时正解的稳定性．更多还原

【Abstract】 In this paper， we consider strictly positive steady－state solutions of some general model of single population with diffusion under Dirichlet boundary condition， We obtain a good understanding of when strictly positive solutions exist as well as their stability when λ is large．更多还原
