| 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。 |

| Abstract: |
| Invulnerability of network is the important support for expedite commu
nication. The definition of network invulnerability is given, networked informat
ion system is expressed by using graph theory. And on that basis, taking a netwo
rked information system topology for example, its core and coritivity are coun
ted, the invulnerability of networked information system in coritivity sense is
analyzed. The results indicate that, in coritivity sense, the networked informat
ion 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 pro
tected. |
| Key words: networked information system invulnerability graph theory core coritivity |
