| 摘 要： | 本文针对重磁异常向下延拓的不稳定性和原始资料中的噪声干扰,提出了一种新方法。该方法将原始资料中的误差作为随机量处理,并通过引入一平滑准则来克服向下延拓的不稳定性,使向下延拓问题得到了较好解决。

| Abstract: | A New method of downward continuation for gravitational and magnetic anomalies is proposed to overcome the unstability and the distortion due to noises. This method treats the error from observed date as a random quantity, and a smothing criterion is introduced to improve the stability of downward con tinuation. Thus, the problem of downward continuation can be well solved. |
