    摘要： In the invention, stator blades are arranged in such a manner that respective intervals between the adjacent stator blades (SV) become unequal at least partly. If the stator blades are arranged as mentioned above, there are formed wave fronts having different moving directions and phases, and these wave fronts are interfered with each other so as to be attenuated. Accordingly, an interference noise is reduced. Therefore, in accordance with the invention, it is possible to reduce an interference noise without enlarging a rotor stator blade interval as well as reducing a used amount of a sound absorption material.

    摘要翻译： 在本发明中，定子叶片以这样的方式布置，使得相邻的定子叶片（SV）之间的相应间隔至少部分地变得不相等。 如果如上所述配置定子叶片，则形成具有不同的移动方向和相位的波前，并且这些波前相互干涉以被衰减。 因此，减少了干扰噪声。 因此，根据本发明，可以在不扩大转子定子叶片间隔的同时减小干扰噪声以及减少吸声材料的使用量。
