While steering with my right hand, I have to control the pitch of the propeller blades.

当我用右手转向时，我必须控制螺旋桨叶片的螺距。

Researchers at MARIN, a Dutch research institute, have blown bubbles onto a propeller's blades, filling the vapour cavities left behind, cushioning their collapse and dampening the resulting noise.

荷兰研究机构 MARIN 的研究人员将气泡吹到螺旋桨叶片上，填充了留下的蒸汽腔，缓冲了蒸汽腔的塌陷，并减弱了由此产生的噪音。

One solution, being developed by researchers at the University of British Columbia (UBC), incorporates flexible polymers into the metal propeller blades, allowing their tips—one of the main sites of cavitation—to bend and twist.

不列颠哥伦比亚大学 (UBC) 的研究人员正在开发一种解决方案，将柔性聚合物融入金属螺旋桨叶片中，使其尖端（空化的主要位置之一）可以弯曲和扭曲。
