摘　　要：针对多处理机系统构造了一类具有较高并行度的并行块预估－校正方法。在ｋ＝２，ｓ＝３的情况下，给出了一个具有四阶精度的并行计算公式，并讨论了该方法的稳定性。A class of parallel block Predictor-Corrector methods is proposed for the multiprocessor system. A three-stages two-block predictor-corrector formula of order four is given and its stability is discussed in this paper. The numerical results indicate that this new method is efficient for the numerical solution of differential equations.
