摘　　要：针对地球远离太阳现象,为讨论地球远离太阳与太阳自转变慢的机制,从动力学角度出发,建立了渐变地日潮汐能耗模型。基于此计算出以前不同年代的地球和所有行星对太阳的潮汐能耗、太阳自转周期、地日距离、地球公转周期和太阳自转周期变慢率等并总结出它们的变化规律。计算结果表明:地球和太阳形成初期,潮汐能耗比现在要高;从46亿年前到现在,太阳自转周期改变了约182 s,地球的公转周期改变慢了2.193×105 s,地球远离了6.935×108 m,公转半径改变了0.46%。In this paper, the earth moving away from the sun and the slowing down phenomenon for the solar rotation have been studied. Based on the dynamics kinetic, the morphing Earth-Sun tidal energy consumption model has been set up to work out the Earth-Sun and the Planet-Sun tidal energy consumptions in different years, the solar rotation periods, the Earth-Sun distance, the earths revolution periods and the slowing rate for the solar rotation periods etc., then their changing laws have also been summarized. Results indicate that in the early stage of the formation of the Earth and the Sun, the tidal energy consumption is higher than that of now; From 4.6 billion years ago till now, the solar rotation has a change of about 182 s, the earth＇s orbital period slows down by 2.193×10^5s, the earth is moving about 6.935×10^8m away from the sun, and the orbital radius has changed by 0.46%. The above results may lead to some meaningful conclusions.
