摘要
通过建立一套求解轴对称体稳态和非稳态温度场的数学模型，编制了相应的９节点等参元有限元程序，并用模型对程序进行了检验，结果证明程序是正确的。
A mathematical expression dealing with the temperature field of steady and transient states of an axisymmetric body is established, and the finite element program for a quadrilateral nine node isoparametric element is worked out and tested.
