摘　　要：网络抗毁能力是确保信息畅通的重要支撑。给出了网络抗毁性的定义,对网络化信息系统进行图论表示。基于系统的核与核度定义,给出了图的核与核度定义。在此基础上,以某网络化信息系统拓扑结构为例,计算出该网络的核与核度,分析了该网络化信息系统在核度意义下的抗毁性能。计算结果表明,该网络化信息系统不具有核度意义下抗毁性最好的拓扑结构。节点13是这个网络化信息系统的"核",应予以重点保护。Invulnerability of network is the important support for expedite communication. The definition of net- work invulnerability is given, networked information system is expressed by using graph theory. And on that ba- sis, taking a networked information system topology for example, its core and coritivity are counted, the invul- nerability of networked information system in eoritivity sense is analyzed. The results indicate that, in coritivity sense, the networked information system topology isn＇t the best invulnerability topology. Node 13 is the core of this networked information system and it is supposed to be key protected.
