| Abstract: | We established the partial effect model of relations between mice and fleas that based on classical ecology model|Logistic equation, and analyzed the model behavior such as equilibrium points and their stability by considering the real biology background. The estimate method of each parameter in the equation and the simulation results of the model are presented with some brief conclusions in the end of paper. This equation can be used to describe the growth dynamic of the relations between flea population and its host under certain conditions. |
