  抽象算子逻辑及其自然演绎系统
• By combining the theory of monotone semiflows generated by rfdes and the fixed point theorem of abstract operators , the existence of positive periodic solutions of rfdes is established under the suitable conditions which are useful and easy to verify . nontrivial applications of our results to some periodic ecological systems are also presented
  通过建立相应的泛函微分方程产生的单调半流理论，结合抽象算子的不动点定理，给出了泛函微分方程存在正周期解的充分条件，最后用若干周期生态系统的例子来验证所得的结果。
• In the second part of this paper ( chapter 4 ) , by constructing the monotone semiflows for retarded functional differential equations with infinite delay , the existence of positive periodic solutions of is given by combining the fixed point theorems of abstract operators . a nontrivial application to periodic ecological systems is presented to illustrate our results
  本文的第二部分(第四章)通过对一类无穷时滞周期泛函微分方程构建其单调半流理论，结合抽象算子不动点定理，获得了其正周期解的存在性，并将所得结果应用到生态系统上。
