本文采用CFD方法，详细分析了空调用多翼离心风机叶道中的气流分布以及进气口偏心的影响。

The vortices flow in the blade passages and the influence of the eccentric inlet of the multi-blade centrifugal fan for air-conditioner have been analyzed numerically by using commercial CFD code.

利用偏心钻具在旋转过程中的离心力和偏心短钻铤的偏重带的支撑作用，减小了钻头轴线倾角，从而减少了井斜。

By taking advantage of rotating centrifugal force and the supporting effect of eccentric short drill collar, we cut off the axis inclination of bit, and avoid well inclination.
