摘要
本文讨论了正则化方法位场向下延拓的四个频率响应公式,分析了它们的特点。这些方法大都能有效地压制由于观测误差或高频干扰所引起的振荡,使下延结果趋于稳定。给出了各种试验的结果。
The four frequency response formulas of rcgularization methods for downward continuation of potential fields are discussed and their characteristics are analyzed. These methods can effectively restrict the oscillations due to the measuring errors or the high frequency disturbances. The trend of downward continuation is stable. The results of various trials are given.
