| Abstract: | In this paper, a class of ecology models in predator pre systems is considered. The necessary and sufficient condition of only unique positive equilibrium of the systems is given by using the mathematical method. The results in Lin shizhe (1995). Wu Yunhua (1997). Wu Yunhua (1997) are extended. |
