摘　　要：通过一有趣的变换和不动点定理,研究一类Lotka-Volterra系统正概周期解的存在性.该结论推广了前人的结果.With the help of an interesting substitution and applying the fixed point theorem, the authors derive a criterion of the existence of positive almost periodic solutions for a class of Lotka-Volterra type systems. The new results improve and generalize the former results.

关 键 词：LOTKA-VOLTERRA系统 正概周期解 不动点定理 时滞 反馈控制
