Wet steam flows within steam turbine leads to two major problems, loss in turbine stage efficiency and bladeerosion.
蒸汽透平中的湿蒸汽流动降低了级运行效率，同时也造成了叶片可靠性下降。

All this is helpful for more accurate prediction of bladeerosion, and for choosing reasonable measures of prevention.
这些都有助于更准确地预测叶片的水蚀和选择合理的防水蚀措施。

Based on study to two aspects of gas-solid two-phase flow and mathematical model, the calculation program for bladeerosion and the countermeasures are resented.
