Abstract: The mathematical model for compressor stator blade is first given by using the bicubic spline surface with improved boundary condition. The intersecting problem among the cubic spnue curve, spline revolution surface and bicubic spline surface is discussed. Finally, a theorem about prediction of subdivision numbers is given.

Key words: intersect line, mathematical model, compressor blade, bicubic spline surface
