研究结果表明：通过优化有效降低了因二次流漩涡、风机蜗舌结构、尾流-射流和正冲角等造成的能量损失，提高了离心通风机性能。

The results show that the performance of optimized fan is improved by lowering the energy loss which caused by the secondary flow vortex, the volute tongue, the wake-jet and the angle of attack.

结果表明，随叶栅稠度的增加，叶栅损失在大部分冲角下呈增高的趋势。

The experimental results show that with the increase of cascade solidity, the cascade loss increases at most incidences.
