In this paper, the authors employ the theory of Mawhin's continuation theorem to study the existence and uniqueness of periodic solutions for a kind of second order functional differential equations with a deviating argument:x″(t)+f(t,x(t),x(t-τ))=p(t).Some new results on the existence and uniqueness of periodic solutions are obtained.
