1.
Effects of inlet boundary layar on aerodynamic performance of bowed compressor cascades with large camber angle;
进口附面层对大转角弯曲扩压叶栅气动性能的影响
2.
The surface-flow topology structures of the compressor cascade with groove surfaces were studied using oil-visualization techniques.
采用油流显示技术研究了沟槽面扩压叶栅表面流动的拓扑结构,通过与光滑叶栅壁面流动拓扑图像的比较,发现沟槽面能抑制叶背附面层的发展,减小附面层内低速流体的展向流动,减弱叶背附面层与叶背角区旋涡的相互作用。
3.
The effects of the stacking line shape on the aerodynamic performance of the compressor cascade with the positive curved blades had been simulated numerically.
数值研究了积迭型线构造型式对正弯曲扩压叶栅气动性能的影响。
6) dispersion

扩散
1.
Simulation analysis on release and dispersion process of liquefied ammonia tank;
液氨储罐事故性泄漏扩散过程模拟分析
2.
Accident of release and dispersion mode in industrial enterprises;

补充资料：X线滤线栅比值
X线滤线栅比值
放射学术语。又称栅比。系滤线铅条高度与其间隔距离的比值。栅比值影响滤线栅吸收散射线的效能，二者呈正比关系，而摄影条件的增幅也随之加大。栅比值的设置范围一般是4～16。实际应用中，栅比不宜过大，多为6∶1和8∶1。
