| Abstract: |
| The existence of periodic solution to a class of third-order functional differential equation with deviating argument xm（t）+f（x'（t））+h（x（t））x'（t）+Σgi（t，x（t-γi（t）））=p（t） was studied and several conclutions were obtained. |
| Key words: functional differential equation devation deviating argument periodic solution |
