从重、磁观测数据中消除干扰及将其局部异常与区域异常分开，经常用的方法是线性滤波，非线性滤波很少应用。本文将叙述线性滤波的局限性，提出一种非线性滤波方法——位变滤波及几种位变滤波的具体公式和应用方法。

Eliminating the interference from the heavy and the magnetic observation data and separating the local anomaly from the regional anomaly, the commonly used method is linear filtering, and the nonlinear filtering is rarely used. This article will describe the limitations of linear filtering, put forward a non-linear filtering method - bit-variable filtering and several specific methods of bit-variable filtering and application.
