在本文中，我们描述了一个操作的有向图，产生一个图与较少的顶点，使新的图的C*-代数是Morita等价的原图。我们统一和推广几个相关的建设，特别是延迟和desingularizations的有向图。
In this paper we describe an operation on directed graphs which produces a graph with fewer vertices, such that the C*-algebra of the new graph is Morita equivalent to that of the original graph. We unify and generalize several related constructions, notably delays and desingularizations of directed graphs.
