摘　　要：以某机组的冷态启动为例,在考虑凝结换热的基础上,用大型有限元分析软件ANSYS10.0对其高中压外缸进行了瞬态温度场分析,为以后的强度计算和寿命评估打下了基础。Taking the some unit＇ s cold start as an example, the transient temperature field of turbine high-intermediate pressure outer cylinder considering condensation heat transfer is analyzed by using the ANSYS10.0 large structure finite element analysis software. So the basis of the strength calculation and life evaluation of turbine high-intermediate pressure outer cyl- inder is founded.
