摘要
本文提出分区异步长解法以求解不稳定温度场，即在温度变化剧烈的区域采用较小的时间步长，而在温度变化速率很小的区域，采用较大的时间步长，从而可大大提高计算效率．
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.
