| Abstract: | Based on the B-spline functionns's interpolation,derivative and integral,this paper presents the method for solving the upward-continuation,the component convertion and the second and the quartic vertical derivatives on an uneven profile and surface with the B-spline functions.The results show that this method is easier and more accurate than other methods. |
