摘要：

By using a fixed point theorem of strict-set-contraction, some criteria are established for the existence of positive periodic solutions of the following impulsive functional differential equations with a parameter {(x)over dot(t) = -a(t) f(t, x(t))x(t) + lambda g(t, x(t), x(t - tau(t, x(t))), t is an element of R, and t not equal t(k) , x(t(k)(+)) - x(t(k)(-)) = I-k(t(k), x(t(k) - tau(t(k), x(t(k))))), k is an element of Z.
