It is shown that the contact interaction enables bottom drillstring to whirl backward, and then an alternate bending stress with higher frequency is produced. So the drillstring fatigue failure could be accelerated. At the same time, a quite strong wallop force of high frequency is produced on the contacting point, and the contacting zone is next to the screw coupling of drill collars. It will easily result in the failure of screw couplings. The research results provide theoretical basis for the prevention of drillstring failure.

研究表明，下部钻柱与井壁的碰摩作用使下部钻柱反向涡动，产生高频的交变弯曲应力，会加速下部钻柱疲劳破坏；下部钻柱与井壁接触点处存在较大的高频冲击力，并且接触区域靠近钻铤螺纹联结处，更容易诱发螺纹联结处失效，该研究成果可为预防钻柱失效提供理论依据。

The results show that boundary layer suction can restrain the corner separated flow, weaken the intensity and scale of passage vortex, and improve the cascade flow capacity.

结果表明，采用吸力面两端吸气对抑制角区分离流动、减弱通道涡强度和尺度、提高叶栅内流动性能的效果要优于其它两种方式，积聚在角区的低能流体由于较大的吸气量而被大量吸除是性能改善的关键。

The results show that various blade stacking lines have a great effect on location, strength and scale of passage vortex at cascade exit, moderate positive curved blade and positive leaned blade can decrease energy loss of guide vane cascade.

计算结果表明：导向器叶栅采用不同积叠线形式的叶片，对导向器叶栅出口截面上通道涡的位置、强度和尺度以及能量损失的影响是显著的，采用适度的正弯或正倾斜叶片可降低导向器叶栅的能量损失。

The round cross-section rods in quayside container crane are very easy to induce wind resonance,and the main form of the rod wind vibration is crosswind vibration,especially the vortex vibration.

岸边起重机川的圆截面杆件容易发生风致振动，风致振动山的主要表现形式为横风向的振动，其中以涡激振动为主。
