We propose a multicomponent growing network model which consists of many types of nodes as well as links only between the nodes of different types. Such a multicomponent network is constructed by (i) introducing a new node of one type and immediately linking it to a preexisting node of the other type, and (ii) creating a new link between two nodes of different types. We then investigate the connectivity of the multicomponent growing networks by means of the rate equations. For a network system with shifted or asymptotically linear connection rate kernels, the degree distributions take scale-free power-law forms, while a random growing network has exponential degree distributions.
我们提出了一种多组分增长网络模型，该模型由多种类型的节点以及仅不同类型节点之间的链接组成。这样一个多组分网络是通过以下方式构建的：(i) 引入一种类型的新节点，并立即将其链接到另一种类型的现有节点；(ii) 在不同类型的两个节点之间创建新链接。然后，我们通过速率方程研究多组分增长网络的连通性。对于具有移位或渐近线性连接速率核的网络系统，度分布呈无标度幂律形式，而随机增长网络具有指数度分布。
