During turbine working, the blade bears strong wind load, air erosion, shock load by minute rough granules, or impact by ultraviolet.

风力机在工作过程中，风机叶片要承受强大的风载荷、气体冲刷、砂石粒子冲击、紫外线照射等外界作用。

A new comparative test approach is provided for the thermal fatigue life experiments of turbine blade under thermal shock. The tested blades and reference blades were mounted in a common vane cascade.

针对涡轮叶片的热冲击疲劳寿命实验，提出了一种新的对比实验方案和措施：将实验叶片和参照叶片组合在同一组试验叶栅上，并且在试验过程中定期对调两种叶片的安装位置。

Finally, the total loss distribution along the blade span of the axial flow compressor is estimated according to an improved end wall loss model and a shock loss model.

再应用改进了的端壁损失和激波损失模型，最终算出轴流压气机设计点损失沿叶高的分布规律。

Even in this high-tech era of amazing medical tools--MRI scanners that can see deep inside the body, gamma-ray beams harnessed to zap tumors, implantable defibrillators that shock the heart to keep it pumping--surgeons still wield an old-fashioned blade to take life into their hands.
