Through the fourth chapter numerical computations , it shows that the method can carry out parallel computations without restrictions of the way of butt joint or overlapping decompositions among sub - domains and reaches high parallel efficiency 通過(guò)第四章的數(shù)值計(jì)算表明本文的方法能不受子分區(qū)之間對(duì)接和重疊方式的限制進(jìn)行并行計(jì)算,且達(dá)到了很高的并行效率。
