Analyses shown that the blade row interaction effect is influenced by the characteristics of disturbance propagation and relative axial position of the blade row.

分析表明，叶片排干涉效应与非定常扰动的传播特征及叶片相对轴向位置有关。

In addition, the wake interaction of upstream blade row and the expansion wave at rotor exit also cause an unsteady force acting on the downstream rotor blade surface.

此外上游静子尾迹以及动叶尾缘出口膨胀波等也是产生转子叶片表面非定常力的因素。
