摘要
本文采用了合理的力学模型和可靠的计算方法 ,研究了近地小行星轨道运动 ,揭示了共振 (轨道共振和长期共振 )在其轨道演化中的作用 ,并初步探讨了近地小行星的起源问题。
In this paper, by adopting the reasonable dynamical models and the effective algorithm, the orbital motion of the Near Earth Asteroids(NEAs) has been detailedly studied, then the effects of mean and secular resonances are revealed during their orbital evolution,finally the origin of the NEAs is simply investigated.
