说明：  复杂网络已经成为物理学中一个富有挑战性的课题。网络灾变是传播过程中随处可见的,这种灾变效应 就像雪崩,迅速在网络中传播。探讨网络灾变的形成机理是十分必要的。本文就复杂网络上的雪崩动力学的研 究进展作一个概述
(Comp lex network is becoming an active field of researches. It is common that catastrophes occur in a network, and like a avalanche sp reading. How do we understand the avalanche?We p rovide a brief review of the avalanche dynamics on comp lex network.)
