This article is to analyse the differences between“Daoshi……Keshi……”and “Keshi……Daoshi……”on sentence types and sentence expression and at the same time approach the character of two kinds of special expression of double turn of sentence types in Chinese.

Effect of blade bowing and local modification on high-turning angle compressor stator performance;

By using of numerical simulation,the effect of applying boundary layer suction on end-wall to the aerodynamic performance for a van with a high-turning angle and meridional divergence was discussed.

The experimental study of curved compressor cascades with large camber angles at different incidences shows that the curved compressor cascades establish obvious opposite "C" type pressure distribution along the blade height on the suction section, which helps move the low energy fluid from the two endwalls to the midspan.

To have a better understanding of how air injection slot position affect surface pressure and surface streamline, a detailed experimental investigation has been undertaken in a large camber angle compressor cascade with air injection slot.
