Extension of yoshizawa periodic solution theorem is mentioned in the third part . nonautonomous three species predator - prey delay diffusion system with michaelis - menten response function is studied . we obtain not only existence of periodic solution of the system , but also sufficient condition of positive periodic solution
由于许许多多现实问题往往都可归结为寻求以微分方程(常微分方程、泛函微分方程)为数学模型的周期解、概周期解，因此本文在第三部分运用yoshizawa型周期解定理的推广，研究了以下具有michaelis ? menten型反应函数的非自治三种群时滞扩散捕食系统的周期解的存在性，给出存在正周期解的充分性条件。
