摘要：In this paper we study the Cucker-Smale model with general network on the line. We will construct an exponential decay quantity which can control the velocity diameter. Therefore we can imply the unconditional flocking emergence if the communication function is nonintegrable. This method is independent of the graph if only the network contains a spanning tree. Thus we prove that unconditional flocking emerges in the Cucker-Smale model for general digraph with a spanning tree. Moreover, in the special case when the communication function is regular inverse power form, unconditional flocking emerges if and only if the exponent  $\beta\leq 1/2$ .
