摘要
鉴于现有逐步积分方法(SIM)的精度控制准则不具有实用性的问题,以解决这一问题为目标,运用另类振动周期的新概念,提出了实用的逐步积分方法精度控制准则,数值算例证明了这种准则的有效性。
In view of the problem that the criteria of accuracy of existing step-by-step integration method（SIM）does not have practicality,With solving this problem as the main research objective,by using of the new concept of other vibration period,a practical criteria of accuracy of step-by-step integration method is derived,numerical examples are given to demonstrate the validity and efficiency of the criteria.
