摘　　要：文章针对一个单级总压比为5的斜流叶轮,研究了小叶片在大叶片通道内不同的轴向及周向位置下对叶轮性能的影响;最终得出的结论是,在压比较高的情况下,小叶片的最佳轴向位置在大叶片的0.3倍全长处,周向位置则应取在槽道中间。Aimed at oblique flow impeller that a single stage total pressure is 5, when the small blade was in the big blade channels, influence of the impeller performance in different axial and circumferential position was studied; we came to the conclusion that under relatively high pressure, the best axial position of the small leaves was 0.3 times in the large leaves, and circumferential position shall be taken in the middle of the channel.
