简要介绍了地球近周日摆动（ＮＤＦＷ）及其在周日重力潮汐中共振的理论背景，利用武汉和Ｂｒｕｓｓｅｌｓ两台站超导重力仪的潮汐观测结果，采用造积方法（Ｓｔａｃｋｉｎｇｍｅｔｈｏｄ）检测ＮＤＦＷ，根据ＮＤＦＷ在４个周日潮波的共振，得到近周日摆动的本征频率和品质因子．考虑ＮＤＦＷ，可精化地球模型，更客观的理解和分析固体潮观测值和其它一些地球物理现象．
This paper briefly introduces the NDFW and its theoretical background of the resonance in the gravity tide on Sunday. Based on the tidal observation results of the superconducting gravimeter in Wuhan and Brussels, NDFW is detected by the stacking method, Based on the NDFW resonance on the four Sunday tidal waves, the eigenfrequency and the quality factor of the oscillating near Sunday are obtained. Considering NDFW, the Earth model can be refined to more objectively understand and analyze tide observations and other geophysical phenomena.
