振捣过程中掌握好振动半径范围，防止重振、漏振。
During the vibrating and tamping, the range of vibrating radius shall be grasped well to prevent from revibration and vibration missing.
计算结果表明，漏流涡对叶片气弹稳定性影响较大，大涡量的漏流涡能抑制叶片颤振发生。
The results show that the tip leakage flow vortex has a great effect on the blade aeroelastical stability and large tip leakage vorticity may restrain blade flutter.
