And use the prior and more consummate ways to carry through vaneaccidence design, These ways have own technology points and disadvantage, In this paperstressly discuss the momentum-element theory way, this way was developed in the basic ofthe two ahead ways, and it overcome their defect. It also use element theory to deal withvane design. In the vane designing and aerodynamical characteristic calculating they bothrelate with intervene gene, so the keystone is to carry through the intervene gene in twocase, thereout to do the vane design and aerodynamical characteristic calculating.

运用翼型的基本概念和风力机叶片的基础外型参数进行叶片设计的预研讨论，并分别运用了Glauert和Schmitz叶片设计方法叶片进行初步设计，这两种方法有其各自技术特点和缺点，文中还着重研究了动量—叶素理论方法，这种方法在前两种设计方法的基础上发展而成，并采用两者的叶素研究方法进行叶片设计，动量叶素理论方法在进行叶片外型设计和叶片气动特性计算都涉及到干涉因子，文中重点对设计和计算情况下的干涉因子进行处理，并由此来设计叶片的外型和进行气动特性的计算。

In the region upstream of vortex breakdown, the sectional streamlines emanating from the leading edge spiral inward to primary vortex and in the region downstream of the breakdown, on the other hand, the streamlines separating from the leading edge are not entrained into the vortex core in the instantaneous sense. Along the axis, the topology of the primary vortex alters several times starting from stable focus near the apex to unstable focus, and lasts back to stable focus near wake edge, the stable hmit cycle and unstable limit cycle are shown in this evolution.

发现在截面流线谱中，即使奇点的类型、数目及位置相同，奇点的连接方式也有可能不同；旋涡破裂点前，主涡由来自前缘的力线卷绕而成，主涡焦点与前缘半鞍点相连，旋涡破裂后，来自前缘的力线不再卷入主涡，主涡焦点与对称面上的鞍点相连：在流体由翼尖流向后缘的过程中，截面流线谱的拓扑结构发生了多次变化，主涡焦点相继由稳定状态转变为不稳定状态，最后又转化为稳定状态，并先后出现了稳定的极限环及不稳定极限环。
