%X 利用重合度理论研究了一类2阶具偏差变元的泛函微分方程axn+f(t,x'(t-τi(t)))+h(t,x'(t-τ2(t)))x(t)+β(t)g(t,x(t-τ3(t)))=p(t)的周期解,得到了周期解存在性的若干结论,推广了已有的结论.<br>By employing the coincidence degree theory, a kind of second order functional differential equations with deviating arguments such as is studied. Some results on the existence of periodic solution are obtained, which generalizes the known results
