| Abstract: | The asymptotic behavior of solutions to a kind of the competition model in the unstirred chemosat is discussed.The comparison principle,maximum principle and theory of permanence in semi-dynamical systems were used.The conditions for the exclusion and persistence of the competitors are obtained.Persistence of the competitors exist for the competition model in the unstirred chemosat under appropriate conditions. |

| Keywords: | chemostat model comparison principle maximum principle permanence asymptotic behavior |
