摘要
本文阐明地球非球形引力位中的高阶次球谐项( 即“短”波项) 对求解卫星运动微分方程的两类数值方法( 单步法和多步法) 选择积分步长的不同影响,并以实际算例证实这一点。
In this paper, it has expounded and confirmed by numerical test that the different effects of the higher degree and order harmonic in the Earth's gravitational potential on numerical methods, by which to solve the equations of the motion of an artificial satellite.
