摘要
]文 [1 ]给出了一类具两个滞量的方程存在周期解的充分条件 ,但并没有给出周期解的表达式 .本文给出了方程 x( t) =-x t-π3 3-x t-2π3 3周期解的部分表达式 .
Paper [1] only gives a sufficient condition that some equations with two retards there are periodic solution. It doesn't give the expressions of periodic solution of those equations. This paper gives some expressions of periodic solution of the equation (t)=-xt-π33-xt-2π33 .
