Based on the computing methods of parabolic interpolation of function with one unknown, Visual FoxPro 6.

In this paper, we discuss the relation between interpolation parabolas and the asymptotic parabola of a plane curve, and prove that if a family of interpolation parabolas of a plane curve has a limit curve then this limiting curve must be the asymptotic parabola of this curve.

The caloric functions and parabolic maximal principles in upper spaces are studied.

Ritz variation method was used to find the numerical relation between the energy near the ground-state of the hydrogen molecular ion H 2 + and the changes of the variation parameter and the bond length,the computation formula of bond length and ground-state energy for H 2 + was also obtained by means of the method of parabolic interpolation.

Applying the least square method and parabolic interpolation to the granualanalysis of soil, this paper gives the method and procedure of computer processing of experimental data.

In this paper,the weighted parabolic interpolation algorithm is firstly improved,and then a new algorithm to magnify images is proposed,which combine the improved weighted parabolic interpolation algorithm and discrete wavelet transformation to realize the image magnification.
