| Abstract: | A method using different time increments in different regions is proposed in this paper to solve the unsteady temperature field by numerical methods.In the regions where the temperature varies rapidly with time,the small time increments are used,while in the regions where the temperature varies slowly with time, a comparative big time increments are used.Thus the efficiency of computation has been improved. |

| Keywords: | temperature field numerical method different time incremets in different regions |
