blade row的用法和样例：
例句
- The numerical simulation technique is used to investigating the secondary flow in the different swept height blade cascades of a turbine last stage.
采用数值模拟技术详细地研究了不同掠高的某蒸汽轮机末级前掠叶片叶栅内部的二次流动。 - The result shows that the frontloaded design for the transonic turbine blade can reduce the intensity of the oblique shockwave and decrease the shock losses.
在跨音速条件下，载荷分布对叶栅的气动性能有着巨大的影响，采用前加载设计可有效地减弱斜激波的强度，减少激波损失，提高流动效率。
