摘要
为了避免Parker公式直接迭代反演的发散性,可在空间域中由平板公式给出界面深度初值,再于频率域中用Parker公式正演出理论重力值,其特点是速度快,工作量小。频率域、空间域交替进行,迭代几次就可以得出界面深度。模型与实例证明这是一种简单、有效的反演界面的方法。
To avoid the divergence of direct iterative inversion from Parker's equation, a procedure can be employed, in which the initial values of depth are given first in the space domain from plate equation, theoretical gravitational values are then calculated in the frequency domain using Parker's equation to solve the forward problem. It is characterized by much less amount of work and computational time. Subsurface depth can be quickly found after merely a few iterations alternatively in frequency and space domains. This approach has been verified to be simple and effective by both models and practical examples.
