摘要
概述了制约线性多步积分公式轨道积分状态的多种因素 ;提出了综合评价线性多步积分公式积分性能的两项新指标。建议在对数值计算有较高精度要求的科研项目中 。
In this paper,the varied factors restricting state of a linear multistep integration formula are stated briefly. Put forward two new technical indices synthesize appraising property of a linear multistep methods for orbital integration. For high precision, we suggest constructing and seeking the more suitable linear multistep integrators and corresponding integral way in the earlier stage of the topic.
