A new approach named swell noise attenuation, which is based on spatial median filter arithmetic, can be adopted to suppress such a noise with some limitations.
基于空间中值滤波算法的巨浪噪声衰减技术对于此类噪声的衰减效果良好，但其应用存在一些限制条件。

Results shown the continued attenuation of the dipole moment in the last 50 years, and the variation of spatial spectrum of geomagnetic field continuously decreased.
研究中发现最近50年偶极矩仍在继续衰减，空间功率谱的变化也呈减小趋势。
