摘　　要：构造了一类适于实时仿真的３步４阶混合方法（ＲＴＨＹＢ４），理论分析和数值试验表明它的稳定性和计算精度好于传统的４阶ＡｄａｍｓＢａｓｈｆｏｒｔｈ算法（ＲＴＡＢ４）．In the present paper,we introduce a class of three step hybrid formula of order 4 (RTHYB4) for real time simulation.Theoretical analyses and numerical experiments indicate that for fourth order methods,the local accuracy and stability of RTHYB4 methods are superior to that of traditional Adams Bashforth method (RTAB4) and modified fourth order Adans Bashforth Moulton Predictor corrector method(RTABM4).From the point of view of weak stability characteristic and computational accuracy,RTHYB4 methods are clearly to be preferred.
