| Abstract: | The theory of coincidence degree is used to study the existence of a periodic solution for the differential equation with delay as follows ax″（t）＋f（x（t））x′（t）＋h（x′（t））x（t）＋gx（t-τ）]=p（t） and a sufficient theorem is obtained for the existence of a r periodic solution of the equation. |
| Keywords: | Nonlinear equation Periodic solution Existence |
