本文研究一类时滞微分系统的周期解，其中ri（i = 1，2，...，n − 1）为正常数.利用Hamilton系统的理论，得到了这类系统存在多个周期已知的周期解的充分条件。
This paper is concerned with finding periodic solutions of differential delay systems and where ri (i = 1, 2,…, n − 1) are positive constants. By using the theory of Hamiltonian systems, we obtain some sufficient conditions under which these systems have many periodic solutions with known periods.
