The birth and death of the leaves are the rapid whirls of the eddy whose wider circles move slowly among stars.

绿叶的生与死乃是旋风的急骤的旋转，绿叶的生与死乃是旋风的急骤的旋转，它的更广大的旋转的圈子乃是在天上繁星之间徐缓的转动。

Because of the asymmetry of the inlet structure and the unstable characteristics of the swirl flow,the spinning center of the gas flow deviated from the geometrical center of the cyclone,which resulted in the asymmetry of the flow field and the change of the three dimensional velocity components.

蜗壳式旋风分离器入口结构的非轴对称以及气相旋流的不稳定性造成了气流的旋转中心与旋风分离器的几何中心不重合，从而导致了气相流场三维速度的非轴对称分布以及速度分量由于基准不同而产生的大小和方向变化。

The real tangential velocity fluctuation indicated that there existed an instability of swirling flow in the cyclone.This instability resulted in the rotation center of the swirling flow deviating from the geometric center of the cyclone,which produced the quasi-periodic oscillation of swirling flow and gave the real tangential velocity fluctuation.

瞬时切向速度的变化反映了旋风分离器内旋转流的不稳定性，这种不稳定性导致了旋风分离器内旋转流的旋转中心与几何中心不重合，旋转中心围绕着几何中心摆动，由此造成了瞬时切向速度随时间的类周期的波动变化。
