| Abstract: | 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. |
