中文摘要：
代数动力学算法首次被用于求人造地球卫星运动方程的数值解，在四阶算法下，与Runge—Kutta算法和辛算法的计算结果作了比较．结果表明，代数动力学算法对于人造地球卫星长期轨道的计算有较高的精度．并讨论了地球四极和八极带谐项对卫星轨道的影响．
英文摘要：
Algebraic dynamical algorithm is used to solve numerically the artificial earth satellite motion equation for the first time, and the result is compared with Runge-Kutta algorithm and sympleetie algorithm under the forth order. The result shows that algebraic dynamical algorithm has higher accuracy than the others in the long-term calculation of satellite orbit. We also discussed the quadrupole and oetupole deformation of the Earth＇ s impact on the satellite orbit.
