摘　　要：阐述了在不影响叶片做功能力和不降低叶片强度的情况下,对叶片前后缘进行了Bizer曲线修正。对并提供了添加叶片前后小圆的详细过程,最后对用该方法设计的某个基元级叶型进行了数值模拟。In this paper, under the condition of not influencing the working ability of blade and not reducing the blade strength, the pre-edge and post-edge are modified by Bizet curves. And the detail process of adding pre and post circular ares in blade is offered. At last, the numerical simulation for one blade with elementary stage designed by this method is carried out.
