摘要：A chemostat model with periodically pulsed input is considered. By
using the Floquet theorem, we find that the microorganism eradication
periodic solution (u1∗(t),v1∗(t),0) is globally asymptotically stable if the impulsive period T is more than a critical value. At the same time we can find that the nutrient and
microorganism are permanent if the impulsive period T is less than the critical value.
