This article analyses the actual reality of network security and briefly intruduces a few of aggressive measures which threaten the safety of network. From these we can see, the passive ways such as firewall and anti-virus software to combat network attack can not meet the increasingly needs of network accessing .As a result, an intrusion detection system must be established to differentiate between the legal accessing and inbreaking attack. That is intrusion detection.

本文首先分析了目前的网络安全现状，简单介绍了几种威胁网络安全的攻击手段，从中可以看出通过防火墙和杀毒工具等软件，被动地防御网络攻击已经不能满足日益增加的网络访问量了，因此必须变被动为主动，对到达的网络访问内容进行审核，来判断是合法的访问还是入侵攻击，这种审核就是入侵检测。

The important task of the exquisite physical chemistry course construction is to make good of the hardware of modern education technology,to develop the potential of the existing and high-quality teaching resources,to increase the network information,to abide by the principles of intellectualized navigation,scientificity,complementarity,interaction,flexibility,feasibility,scalability,artistic quality,instructiveness,stability and step by step,etc,integrate and make the network teaching materials normative overall and beneficial to the students.

精品课程建设要求逐步建立能使广大学生受益的网络教学资源，只有这样才能挖掘出现有教学资源的潜力和最大化地利用现有优质教学资源。为此，我们充分利用现代教育技术的良好硬件环境，在原有工作的基础上，增加更多的网络信息，全面整合和规范物理化学课程的网络教学资源，并以此作为精简授课学时、激发学生学习兴趣和学习动机、提高教学效果的一个重要途径。1网络教学在物理化学教学中的作用网络的时空无限性不仅构筑了新的人类生存空间，也构筑了新的教育空间。

The results show that small world network model could explain the big change of intensiveness and connectedness in forming process. And individual selection value function could explain the stable intensiveness, connectedness in growing and mature process. Combined the both, the characteristics of the whole process could be reflected.

研究表明，小世界网络模型模拟的集群网络具有集群形成期网络整体密集性和连通性剧烈变化的特征，而个体选择价值函数模型可以解释集群网络的成长期、成熟期的密集性和连通性趋于稳定的特征，将2种演化规则相结合，则可以反映集群网络从形成期到成熟期的各生命周期特征。

So we can neither indulge in the network,nor keep clear of it.

所以我们既不能沉迷于网络，也不能不接触网络，我们要充分利用网络，充分利用网络带给我们的好处，避免网络带来的一些坏处。

Halogen ion can enter and break the phosphate glass network when they exceed certain content. The short range structure of metaphosphate and polyphosphate glasses are all built with phosphate chains. Most of lead ions still act as network modifiers, and some lead ions enter glass network to form tetrahedron or Pb-O-P linear linkages.

Br〓和F〓离子达到一定浓度时就会进入网络，使得玻璃网络发生断裂。P〓O〓含量为50mol％和40mo1％的玻璃样品结构都为链状结构，一部分pb〓离子进入玻璃网络中作为网络形成体，形成四面体或Pb-O-P键：而大部分的pb〓离子仍然作为网络修饰本。
