探讨了恒化器中三级营养n个种群的竞争模型。利用比较原理得到物种共存，推导出系统的有界性以及耗散性，并且讨论了系统平衡点的存在性和稳定性。

A competition model about three trophic levels of n-species in a chemostat was considered. Coexis-tence about this system was occurred by using comparison theorem. The boundedness and dissipativeness of the system were obtained,and the existence and stability of the system’s equilibrium were discussed.
