轴流泵综合特性曲线中等效率曲线的B样条拟合方法

ubic uniform B-spline which is applied to the fitting method for isoefficiency curve of the comprehensive characteristics of the axial flow pump can be introduced here, and various shapes of isoefficiency curve are achieved by setting different curve ports according to their properties. It not only can greatly reduce the complexity of traditional method of drawing isoefficiency curve, but also can be used in the fitting of other complicated similar curves.
