摘要
本文给出了一类积分微分方程组存在和不存在正解的若干充分条件．
In this paper,we establish the conditions under which the system of integrodifferentialEquations cannot have a solution on an interval[T,],such that each of its Components is positive on ,We also present the sufficient conditions for the existence of A solution on an interval ,T>0,of the system such that all its components are positiveOn.
