摘      要：In this paper the author discusses the following first order functional differential equations: x (t) +integral from n=a to b p(t, ξ)x[g(t, ξ)]dσ(ξ)=0, (1) x (t) +integral from n=a to b f(t, ξ, x[g(t, ξ)])dσ(ξ)=0. (2) Some suffcient conditions of oscillation and nonoseillafion are obtained, and two asymptolio properties and their criteria are given. These criferia are better than those in [1, 2], and can be used to the following equations: x (t) + sum from i=1 to n p_i(t)x[g_i(t)] =0, (3) x (t) + sum from i=1 to n f_i(t, x[g_i(t)] =0. (4)
