The study of networks pervades all of science, from neurobiology to statistical physics. The most basic issues are structural: how does one characterize the wiring diagram of a food web or the Internet or the metabolic network of the bacterium Escherichia coli? Are there any unifying principles underlying their topology? From the perspective of nonlinear dynamics, we would also like to understand how an enormous network of interacting dynamical systems-be they neurons, power stations or lasers-will behave collectively, given their individual dynamics and coupling architecture. Researchers are only now beginning to unravel the structure and dynamics of complex networks.
对网络的研究遍及所有科学领域，从神经生物学到统计物理学。最基本的问题是结构方面的：如何描述食物网、互联网或大肠杆菌代谢网络的接线图？它们的拓扑结构是否存在统一的原理？从非线性动力学的角度来看，我们还想了解一个由相互作用的动态系统构成的庞大网络——无论是神经元、发电站还是激光器——在给定其个体动态和耦合结构的情况下将如何集体表现。研究人员直到现在才开始揭示复杂网络的结构和动态。
