| Abstract: | 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. |
