摘要	We consider the existence of positive omega-periodic solutions for the periodic equation x'(t) = a(t)e(x(t))x(t) - lambda b(t)f(x(t - tau(t))), where a, b is an element of C(R, 10, infinity)) are omega-periodic, integral(omega)(0) a(t)dt > 0, integral(omega)(0) b(t)dt > 0, f is an element of C ([0, infinity), [0, infinity)), and f (u) > 0 for u > 0, tau(t) is a continuous omega-periodic function.
