摘要
本文对常用的数值方法(Adams、Cowell、RKF、GBS、Everhart,Taylor和Krogh方法)就四个主要指标(局部截断误差,数值稳定性,复杂性和普适性)进行评述和比较,并提出一些初步的结论供数值积分工作参考。
There are four indexes for evaluating various integrators. They are the local truncation error, the numerical stability, the complexity of computation and the quality of adaptation. A review and a comparative study of several numerical integration methods, such as Adams, Cowell, Runge-Kutta-Fehlberg, Gragg-Bulirsch-Stoer extrapolation, Everhart, Taylor series and Krogh, which are popular for constructing ephemerides with high precision, has been worked out in this paper. A few of preliminary conclusions and advices are provided in Section 7 for the relevant scientists and engineers.
