摘　　要：本文阐述了设计具有弯扭静叶的３００ＭＷ汽轮机低压缸末级时应该使用欧拉法来代替传统的流函数法的计算思想，并使用依据欧拉法编制的通流计算程序完成了末级静叶的弯扭改型设计。计算结果表明，改型后的设计比原型有较大的改进。Abstract The idea of using the Euler method instead of the tranditional stream function method in calculations during the design of the 300MW steam turbine'slow pressure cylinder's last stage with slanting twisted static blades is described. The improved blading design was accomplished by using a program basedon the Euler method. Calculated results show that more can be gained with theimproyed design than with the original one.
