| 摘 要： | 鉴于无法找到描述Kuiper带天体动力学演化的分析解,本文采用数值模拟的方法,即通过数值积分,得到由太阳、海王星和Kuiper带天体组成的限制性三体问题中Kuiper带天体随时间演化的数值解.结果表明,经长期演化后,共振带中的一些天体的偏心率明显被激励;Kuiper带天体的轨道偏心率和倾角的激励程度和天体的初始轨道半长径、偏心率、倾角有关.

| Abstract: | Numerical Solution for evolvement of KBOS with time in restricted three-body problem that only contain Sun,Neptune and Kuiper belt object.has been obtained.Results show that,after long-term evolution,some bodies' eccentricity in resonance region has been inspired.Orbital eccentricity and inclination's inspire degree are related to their initial orbital semimajor axis,eccentricity and inclination. |

| Keywords: | kuiper belt orbital eccentricity orbital inclination numerical simulation |
