In the wake of the plane crash, original copies of the album were recalled and replaced with a cover image of the band standing against the completely non-depressing black background.
就在空难之后，最初发行的唱片被召回并且把封面换成另一张图，乐队面对着一个毫不压抑的黑色背景。
The results show that the rotor near-wake is distorted because of the flow field of the fuselage, resulting in large variation on the induced velocity distribution at the rotor plane.
在机身影响下，旋翼近场尾涡形状发生畸变，从而改变桨盘处的诱导速度分布。
The variation of the induced velocity distribution at the rotor plane caused by the fuselage through distorting the rotor near-wake is much larger than that induced by the fuselage directly.
尾涡畸变引起的诱导速度变化比机身直接在桨盘处诱导速度大得多。
The results of the axial wake at the propeller plane showed that the calculation method is reasonable.
对桨盘处轴向伴流的计算表明，计算结果是合理的。
In the experiment, a simplified aircraft model (with tail wing) is employed to construct a 4-vortex wake system consisting of a pair of tip vortices and a pair of counter rotating tail plane vortices.
试验采用简化的飞机模型(有尾翼)，建立了包含一对翼尖涡及一对反向旋转的尾翼涡(通过以负迎角安装尾翼得到)的4涡尾流系统。
