几句英译汉，高手进！加分！

一段摘要，急求高手人工翻译，语句可以不太专业，但不要任何在线翻译。谢谢！！译好再加20！
abstract: The current paper reports a numerical investigation of stall inception in a transonic
compressor rotor, NASA Rotor-67, by using the whole flow passages in the computations. Surface
roughness is added to one of the blades in order to trigger rotating stall. During stall inception,
the tip clearance vortex moved away from the suction surface of the roughened blade’s
upper neighbour, leading to vortex breakdown. The stall cell was found to propagate opposite
the direction of the blade rotation at about 30 per cent of rotational speed. The effect of air
bleeding on stabilizing the compressor is also studied in this work. The mean mass flowrate
removed from the bleed valves was
1.2 per cent of the mainstream flowrate. This amount of
bleeding was found to effectively suppress the stalling disturbances.

本论文汇报了关于压气机转子失速初期的数字科学研究
NASA Rotor-67, by using the whole flow passages in the computations.
NASA 旋转器-67，估计全部使用流道。
Surface roughness is added to one of the blades in order to trigger rotating stall.
增加其中一个叶片的表面粗糙是为了引起旋转失速。
During stall inception, the tip clearance vortex moved away from the suction surface of the roughened blade’s upper neighbour, leading to vortex breakdown.
失速初期的时候，齿顶间隙涡流离开表面粗糙的叶片之上的吸力面，导致涡流减弱。
The stall cell was found to propagate opposite the direction of the blade rotation at about 30 per cent of rotational speed.
失速区发现以约30%的角速度与叶片相反的方向传播
The effect of air bleeding on stabilizing the compressor is also studied in this work.
本论文还学习了研究了稳定压气机的排气效果
The mean mass flowrate removed from the bleed valves was 1.2 per cent of the mainstream flowrate.
排气阀排出的平均质量流量是主流流量的1.2%
This amount of bleeding was found to effectively suppress the stalling disturbances.
这个排放量发现可以有效的抑制失速问题
