摘要
对单圆弧、双圆弧和抛物线等三种中线构成的叶型进行了理论分析和计算。结果表明，从叶道的进口到出口，轴流通风机叶片对气流的作用是一个渐变的能量传递过程。叶型中线的形状决定了叶片对气流的作功规律。
Theoretical analysis and calculation has been carried out on blade formed by three lines of single,double circular arc and parabolic comet.The result is that from inlet to outlet of the blade channel,Axial fan blade effected on air flow is a gradually changed process of energy transmitting.The shape of blade form centerline determined the work regular of blade to airflow.
