【摘要】：Milankovitch理论认为,地球表面日照量受地球运动变化的影响,这些改变又会导致地球气候的变化。因此,古气候学的研究需要相关地球运动变化的精确信息。目前,关于地球长期平动和转动的最新理论是La2004,La2010和La2011模型,它们主要通过数值积分行星轨道和地球自转运动方程得到;这些结果已被用于过去50 Ma的地质记录研究中。而超过这一时间范围,解的准确性会由于混沌效应迅速降低。主要介绍这些天文理论的相关内容以及有关地球运动演化方面的最新进展。第2章是关于数值积分太阳系长期运动,第3章介绍长期岁差方面的内容,第4章给出有关地球运动的长周期分析,第5章则讨论数值解的稳定性和太阳系稳定性方面的情况,最后是对目前地球运动长期演化领域的总结以及对未来的展望。
[Abstract]:The Milankovitch theory suggests that the amount of sunlight on the Earth's surface is affected by changes in the Earth's motion, which in turn lead to changes in the Earth's climate. Therefore, paleoclimatological research requires accurate information on changes in the Earth's motion. The latest theories about the long-term translation and rotation of the earth are La2004La2010 and La2011 models, which are mainly obtained by integrating the planetary orbits and the equations of rotation motion of the earth numerically. These results have been used in the study of geological records over the past 50 Ma. The accuracy of the solution will be reduced rapidly due to chaotic effects. This paper mainly introduces the relevant contents of these astronomical theories and the latest progress in the evolution of the Earth's motion. Chapter 2 is about numerical integration of the long-term motion of the solar system. Chapter 3 introduces the long-term precession, chapter 4 gives the long-period analysis of the earth's motion, and chapter 5 discusses the stability of the numerical solution and the stability of the solar system. Finally, the paper summarizes the long-term evolution of the earth motion and prospects for the future.
