具定量输入毒素的广义Logistic模型的性态

Dynamics of the Effect of Constant Toxicant on the Populations Stimulated by Generalized Logistic Model

讨论了受定量输入毒素污染的种群生长广义Ｌｏｇｉｓｔｉｃ 模型的动力学性态． 通过研究模型解的渐近性质， 从而得到生物种群受不同程度的环境毒素影响而产生不同结局（ 灭种或持续生存）

Dynamics of the generalized Logistic model polluted by constant toxicant of time is studied in detail.By analyzing the asymptotic properties of the solution,we obtain the polluted conditions that will lead to different results(persistence or extinction) to the populations.
