摘要

研究了在木星附近的近轨小行星对平均运动共振(3:1、4:1、5:2、7:3)的动力学演化。通过对未来运动方程和过去运动方程的积分，分析了对动力学演化的情景。结果表明，由于亚尔科夫斯基效应，小行星的半长轴漂移值和符号与近距离接触的机会以及通过共振时散射的可能性有关。

DYNAMICAL EVOLUTION OF ASTEROID PAIRS IN CLOSE ORBITS NEAR RESONANCES

Dynamical evolution of asteroid pairs in close orbits near Jovian mean motion resonances (3 : 1, 4 : 1, 5 : 2, 7 : 3) has been researched. We analyzed scenarios of pair’s dynamical evolution by integrating the equations of motion in the future and past. It’s shown, that the op-portunity of close encountering, as well as the possibility of scattering under passing through the resonances, is dependent on the asteroids’ semimajor axis drifts values and signs due to the Yarkovsky eﬀect.
