摘要
本文在研究小行星轨道演化中,对不同的通约比所对应的轨道共振现象作了较详尽的数值分析,考查了相平面上平衡点附近轨线分布结构的变化,从而对小行星的空间分布特征(空隙和聚集)给出了初步解释.
In studying the orbital evolution of asteroids, we have made numerical analyses more carefully and completely for the phenomenon of orbital resonances corresponding to various commensurate ratios and investigated the structural variations in the distribution of the trajectories near the equilibrium points in the phase plane. Hence a preliminary explanation is given for the dynamical mechanism of the formations of the gaps and concentration in the space distribution of asteroids.
