摘要:

A direct constrained least‐squares cubic spline method suitable for use with noisy experimental data is explained in detail and applied successfully to examples of shear‐thinning (pseudoplastic), viscoplastic (Bingham), and shear‐thickening (dilatant) fluids. A regularizing linearized curvature smoothness constraint is employed.
