摘　　要：研究了一类三阶具偏差变元的泛函微分方程:x'''(t)+f(x'(t))+h(x(t))x'(t)+Σni=1gi(t,x(t-τi(t)))=p(t).的周期解的存在性,得到了若干结论.The existence of periodic solution to a class of third-order functional differential equation with deviating argument xm(t)+f(x'(t))+h(x(t))x'(t)+∑i=1ngi(t,x(t-τi(t)))=p(t) was studied and several conclusions were obtained.

关 键 词：泛函微分方程 偏差变元 周期解
