摘　　要：工程中有大量的具有循环对称特点的温度场的求解问题。本文对具有循环对称条件的非线性瞬态温度场问题给出由泛函表达的方程及用有限元法计算的实例。本方法使具有循环对称特点的温度场的计算可在一个循环周期内进行，从而大量减少输入数据的准备工作，减少内存占用和计算时间。In this paper, a set of functional equations concerning nonlinear and instant temperature field with circulation symmetry condition frequently occurring in engineering is presented within one circulation periodic region with an example successfully solved. By using this method, the input data can be greatly reduced, and furthermore, memory space and calculation time can be saved.
