摘　　要：运用锥拉伸与压缩不动点定理,研究一类泛函积分方程的正解．把所得结果应用于研究常微分方程积分边值问题正解的存在性,所得结果推广和本质上改进了马如云等作者最近的一些结果．We study the existence of positive solutions for a functional integral equation using a fixed point theorem of expansion and compression type in a cone. Finally the main results are used to establish some existence results for positive solutions of integral boundary value problems for ordinary differential equations. The results presented substantially generalize and improve some recent ones due to Ma et al.

关 键 词：泛函积分方程 正解 积分边值问题
