摘要
结合观测异常及其垂直梯度的特点,给出了一种新的快速曲化平方法。这种方法利用了位场的调和性质,借助了三次样条优良拟合特点。模型计算表明,该方法计算速度快,精度较高。
By adquately combining the features of total field anomaly and its vertical gradient, the authors present a new method which is fast to reduce the anomaly on an arbitrary surface to a plane. In the algorithm, spline is used to fit the data, which has the attribute of fine fitting. The calculation result of the theoretical model shows that the theory derivation is correct and precision is high.
