If patients do experience a decreased ROM as a consequence of impingement, then subluxation and edge loading may occur, which can lead to a higher wear rate and early failure.

如果病人感觉到降低活动度是撞击的结果，然后半脱位和边缘负荷可能发生，这能导致更高的磨损率和早期的失败。

The test results show that the impingement heat transfer from the rib roughened surface is considerably affected by the initial crossflow rate.

实验结果表明，初始横流率对肋粗糙表面的冲击换热有重要的影响。
