摘要
应用在IBM 4341计算机上建立的Hansen普遍摄动计算方法的软件,快速自动推导出了Flora群里五颗其周日平均运动n～997″小行星:(261)Prymno,(587)Hypsipyle,(753)Tifis,(783)Nora,(1598)Paloque和一颗n～975″小行星(855)Newcombia所受木星摄动的三角级数解。与过去用Bohlin群法计算所得近似解作比较,因现在计及了(3E-10θ)长周期项和精化了(E-3θ)等主要周期项的系数,使得这些小行星普遍摄动计算的结果有了明显的改进。
This paper has rapidly and automatically computed the trigonometric series solutions of general perturbations of five asteroids: (261) Prymno, (587) Hypsipyle, (753) Tifis, (783) Nora, (1598) Paloque which mean daily motion n-997″ and one asteroid: (855) Newcombia which mean daily motion n-975″ due to Jupiter by applying the computing program of Hansen method established on IBM 4341 computer and compared with the ap-proximate solutions computed with Bohlin group method before. It is shown that the new results of general perturbations for those asteroids have been obviously improved because of considering (3E-10θ) long periodic term and refining the coefficients of main periodic terms including (E-3θ) term, etc.
