摘要
提出用B样条函数求解曲线、曲面上重磁位场的向上延拓,水平、垂向导数计算,磁异常分量互换的方法。该方法的特点是:原理简明,程序通用性强,计算精度高。
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.
