摘　　要：在冥王星的运动中存在着三个共振 ( 3∶2平运动共振、Kozai共振以及 1∶1超级共振 )。这三个共振保证了冥王星运动的稳定性。我们通过大量的数值模拟来探索三个共振在轨道根数空间的区域分布以及几颗大行星对它们的影响。结果证实了 1∶1超级共振为Kozai共振的次级共振 ,并表明了 3∶2共振是三者中最重要的 ,木星对三个共振的影响最大。In the orbit motion of Pluto, there exist three resonances to keep its stability. They are the 3∶2 mean motion resonance, Kozai resonance and the 1∶1 super resonance respectively. By numbers of numerical integrations, we explore the three resonance regions in element space and the effects of the giant planets on the three resonances. It is confirmed that the 1∶1 super resonance is a secondary resonance to Kozai resonance. The results also show that the 3∶2 resonance is the most important among the three resonances, and Jupiter has the most important effect on the resonances.
