摘要
讨论具有周期扰动项的ｎ维无穷延滞的Ｌｉéｎａｒｄ型方程ｘ¨＋２Ｆ（ｘ）ｘ２ｘ＋ｇ（ｔ，ｘｔ）＝ｐ（ｔ）的周期解，给出了存在周期解的一些充分性判据．
The problem of the periodic solutions for n-dimensional Liénard equations with infinite retardation of the following form is discussed x¨+ 2F(x)x 2+g(t,x t)=p(t). some new conditions which guarantee the existence of periodic solutions are given.
