中文摘要：

由两类不同主体构成的复杂系统,若同类主体间、异类主体间都存在着相互作用关系,则该系统可以用二元网来抽象描述.无标度二元网的网络整体度分布及两类节点各自的度分布都服从幂律分布.通过构建无标度二元网模型,尝试解释无标度二元网的形成机制.研究无标度二元网的拓扑结构性质发现,模型的不同类节点规模比参数及连接概率参数对网络的平均最短路径和群聚系数有着重要影响.无标度二元网模型的最短路径长度较小,其幂指数变化范围在2.5到3.5之间.

英文摘要：

Complex system consisted of two different type agents for which relations between same type agents and between different type agents can be described by bielemental network.The degree distribution of scale-free bielemental network follows a power-law distribution,and the degree distribution of the two subnetwork also follow a power-law distribution respectively.To explain the generation mechanism of scale-free bielemental network a model is constructed.Through studying the topology feature,it is found that the ration of one type to the other type and the link probability of different type agents have important affection on the average path length and clustering coefficient of scale-free bielemental network.The average path length of scale-free bielemental network is shorter than that of one-mode random network,and the power-law indices range from 2.5 to 3.5.
