The working principle and key parameters of the blade separator were introduced, and tests on the performances of adding the separator on the contra-rotating axialflowfan were carried out.
介绍了叶片分离器的工作原理和关键参数，并对加装了叶片分离器的对旋轴流风机进行了性能测试试验。

The loss model and the efficiency model of the axial-flowfan were established to optimize parameters and to estimate design rationality.
建立了轴流风机损失模型进行参数优化，根据轴流风机效率模型来判定设计参数的合理性。
