摘要：
By using the continuation theorem of coincidence degree theory, the existence of a positive periodic solution for a delayed predator-prey model with nonmonotonic functional response [GRAPHICS] is established, where a(t), b( t), mu( t) and d( t) are all positive periodic continuous functions with period omega > 0, m > 0 and tau >= 0 are constants.
