本文介绍了一种改善水电站水轮机转轮空化的新方法。其技术路线是转轮翼型测绘──空化区翼型优化──转轮修型。实践证明该方法具有良好的效果，特别适合于大、中型水轮机。
This article describes a new method to improve turbine cavitation in hydropower stations. The technical route is the rotor airfoil mapping ─ ─ air-wing airfoil optimization ─ ─ runner repair. Practice has proved that this method has a good effect, especially suitable for large and medium-sized turbine.
