Based on Netherlands ship model Basin s open-water tests,CPP s thrust coefficients and torque coefficients in four-quadrant under different pitch ratio of screw and different types of CPP were obtained by using the method of Akima interpolation,and CPP s thrusts and torques were obtain.

Therefore,kinds of factors causing errors are discussed,and then elimination method,improved Akima interpolation and other related solving methods are presented.

Analyzing the diode detecting characteristic by using spline interpolation technique;

The application of spline interpolation to motion simulation;

Analysis of spline interpolation in boundary element numerical calculation;

A class of C1 continuous algebraic trigonometric blending interpolation spline curves is constructed based on the definition of free form algebraic trigonometric blending base functions.

The worst case identification error upper bound is analyzed, and an explict error upper bound is obtained when the Lidstone interpolation spline and triangular window are used.

This paper presents a method for the graphical representation of curved,fitting of data with cubic polynomial local area interpolating splines, and deal with existence, uniqueness, approximation degree of the fitting.
