The results show that a positive bowed blade can restrain the corner separation and change the separation configuration, while it can not avoid the flow separation on the suction surface.

结果表明，正弯可以有效遏止角区分离，改变吸力面的分离形态，但不能完全消除吸力面的分离。

Through studying the structure of the unsteady flow field in vibrating cascades, the coupling relationship between flow separation on the suction surface and blade vibration is revealed.

此外，通过对振荡叶栅非定常流场结构的研究，发现了叶片吸力面气流分离与叶片振动之间的耦合关系。

The result indicated that the interaction between the boundary layer on the suction surface of blade and on the endwall thicken the boundary layer on the suction surface.

实验结果表明，角区中端壁附面层和叶面附面层的堆积使得叶面附面层变厚；
