摘要：

The existence and the global attractivity of a positive periodic solution of the delay differential equation (y) over dot(t) = y(t)F[t, y(t - tau(1)(t)),..., y(t - tau(n)(t))] are studied by using some techniques of the Mawhin coincidence degree theory and the constructing suitable Liapunov functionals. When these results are applied to some special delay bio-mathematics models, some new results are obtained, and many known results are improved.
