摘　　要：针对地球自转变慢现象,从动力学角度出发,提出每百年潮汐能耗的概念,并建立了渐变地月潮汐能耗模型。基于此,计算出以前不同年代的地球和月球的潮汐能耗、地球自转周期、地月距离、月球公转自转周期和地球自转周期变慢率等,并总结出它们的变化规律。研究结果表明:地球和月球形成初期,潮汐能耗非常高,是现在的1 6.8倍,地月距离非常近,是现在距离的39%等,并给出了一些有意义的结论。Considering the deceleration phenomenon of the earth＇s rotation, this paper presents the concept of century tidal energy consumption from the view of dynamics and sets up the gradient Earth-Moon tidal energy consumption model. Based on this, it has worked out the earth and the moon＇s tidal energy consumption in different years, the rotation period of the earth, the earth-moon distance, the deceleration rates of the rotation and revolution periods for both the earth and the moon, etc. while generalizing their changing rules. The study indicates that in the early formation stage of the earth and the moon, the tidal consumption is 16.8 times as high as today＇s, and the earth-moon distance is 39% as far as what it is now. Some meaningful conclusions are also given.
