摘　　要：本文在总结国内外制造商有关空冷末级叶片设计方面的技术特性。及相应技术规范基础上，提出了空冷末级叶片设计的技术条件，实现既统一技术术语和基本准则，又放宽具体结构和保留独自风格的空冷末级叶片设计方法。为制订供国内汽轮机制造行业和发电行业在空冷末级叶片的设计制造及运行方面共同参照执行的一个国家标准提供技术支持。Both technical characteristics and technical criterions have been summarized in this paper about how to design Last Stage Bucket （LSB） of air-cooled steam turbine by domestic manufacturers and overseas manufacturers. The technical criterions of designing LSB have been introduced briefly for air-cooled steam turbine .The glossaries and basic guide line about designing LSB have been carried out. The idiographic structure of LSB has not been limited .It will provide technical support for mapping out national standards about designing LSB of air-cooled steam turbine for both turbine manufacturers and electricity generator manufacturers.
