| 摘 要： | 用Ｎｅｔｔｌｅｔｏｎ等人的方法，将区域场与局部异常振幅进行了滤波分离。针对常规多边形滤波器判别速度慢的特点，制定了一种快速判别的计算方案，并进行理论模型验证，最终用于实测重力资料的处理。

| Abstract: | Using Nettleton's method,the author made filtering separation for amplitude spectra of regional anomalies and local anomalies.In view of the low discrimination velocity of the traditional polygonous filter,the author worked out a calculation scheme for rapid discrimination and made theoretical model verification.The technique was eventually used to process measured gravity data. |
