| 摘 要： | 分析了弯扭叶片中，叶片力的径向分力对沿叶高反动度的影响，及对变工况时脱流特性的影响。数值计算表明，在大功率汽轮机末级叶片中采用弯扭叶片后对脱流特性有较大影响。相对脱流高度减少。

| Abstract: | This paper is intended to analyse how the radial component force which opposed on the dending blades affect the reaction along blade and flow separation characteristics of varying duty. The value calculation shows that bending blade may make considerable influence of flow separation in last stage of large steam turbine, in that the relative height of flow separation is reduced. |
