在进行经济技术性分析后，最终确定风机的设计方案，进而确定通风机适当的级型式、叶轮尺寸、轮毂比、转速和叶片数等基本参数。
Final design scheme is confirmed after economic and technical analyse. Then, axial fan 's stage type, impeller diameter, hub ratio , specific speed and the number of blades are decided.
阐明了动静叶片数的匹配及其轴向间距的配置在轴流通风机气动设计与结构设计中占有重要位置。
It is the main points that rotor and stator blades matching and the axial distance disposition in pneumatic and structural design for axial fan.
同时，通风量及冷却数随外界侧风风速的变化规律在不同的流量下相似，说明所得结论具有通用性。
Meanwhile, the variation regularity of ventilation and cooling number with wind speed at different flow rates air similar illustrate the conclusions of generality.
