摘　　要：In this paper we give an applicable parameter formula about the bifurcationand stability of periodic solution for a four-dimensional differential system. By using thisresult in a simple electronic neural network system, we obtain a strict condition of theexistence of periodic solution.In this paper we give an applicable parameter formula about the bifurcationand stability of periodic solution for a four-dimensional differential system.
