摘　　要：提出了多叶通风机匀加速叶道的定义 ,以及可形成匀加速叶道的叶片断面廓线的几何近似作图方法。同时提出了匀加速叶道的当量锥角 ,以及寻常叶道非匀加速区面积系数两个新概念。The definition of multiblade fan uniform acceleration blade channel and geometric approximate construction method of blade section contout is put forward. The conception of uniform acceleration blade channel equivalent cone angle and that of ununiform acceleration band area factor of common blade channel is also put forward at the same time.
