摘　　要：通过对汶川8.0级地震前,龙门山地区小震活动与月球上中天、下中天时刻对应关系的讨论,得到龙门山小震活动与月球引潮力的低潮对应关系不明显。另外,对龙门山小震与固体潮理论曲线对应的讨论,得到每组小震的头震在接近固体潮曲线的谷底发生,即地震的发生与固体潮的低潮有关。在临近大震前,地震多发生在固体潮曲线的上升部位,即引潮力增长速率最大处。The corresponding relation between the activities of the small earthquakes in Longmenshan region before Wenchuan M8.0 earthquake and the times of the moon transit and the moon lower culmination had been discussed.The corresponding relation between the activities of the small earthquakes in Longmenshan region before Wenchuan M8.0 earthquake and low tide of the moon tidal generation force is not obvious.We obtained the first earthquake of the every small earthquake swarm occurred at the time of low tidal curve and the earthquakes are connected to the low tides.Especially,the big earthquake mostly occurred when the tidal rose,at the same time,the velocities of the moon tidal force increased greatly.
