网络信息政策有关研究问题是图书馆学、信息管理科学的前沿课题，燕金武在这部论著中首先分析了网络信息政策的概念、特点、研究方法和政策环境，研究了网络信息政策的总体框架，文献综述部分反映了该选题相关领域的前人成果和前沿状态，注意归纳总结现存的问题。探讨了网络信息政策的研究方法，这是适应网络环境的变化，信息管理和信息政策研究的新的学科增长点，扩大了图书馆学、情报学和信息道学的学科范围。在此基础上，对网络信息政策值得关注的若干问题进行探索性研究，如网络信息政策内涵、网络信息政策与信息政策关系、国际网络接入、网络信息内容管理政策、网络接入政策等，这是对国内该研究领域的补充。通过对国外网络信息政策和国内网络信息政策的比较，探讨我国应采取的网络信息政策，对我国网络信息政策的制定有参考价值。

Your first PC can be intimidating. You’re probably panicky that you’ll hit a wrong key and send your information to some high-tech black hole or cause your PC to self-destruct. Not to worry. PCs Just the Steps For Dummies gives you simple directions for getting stuff done with your PC—everything from turning it on to using the Internet or a network. The book’s design features two columns， with numbered step-by-step instructions on one side and corresponding illustrations， screen shots， or photos on the other. You just pick the task you want to do and look up practical， no-nonsense how-to. This guide covers：　Hardware basics and peripherals， including printers， faxes， and scanners　Working with Windows XP， including managing memory and working with files and folders　Working with sound and video　Going online， searching the Web with Internet Explorer， and e-mailing with Outlook Express　Networking， including configuration and connection and sharing folders or printers　Protecting and troubleshooting your PC　With practical organization and a task-oriented approach， this book will have you inspired instead of intimidated. You won’t get an unabridged history of computers and a lot of gibberish; you will get clear， easy-to-follow instructions that help you get your tasks done efficiently on your PC.

The four-volume set LNCS 3991-3994 constitutes the refereed proceedings of the 6th International Conference on Computational Science， ICCS 2006， held in Reading， UK， in May 2006.The main conference and its 32 topical workshops attracted over 1400 submissions. The 98 revised full papers and 29 revised poster papers of the main track presented together with 500 accepted workshop papers were carefully reviewed and selected for inclusion in the four volumes.The papers span the whole range of computational science， with focus on the following major themes： tackling grand challenges problems; modelling and simulations of complex systems; scalable algorithms and tools and environments for computational science. Of particular interest were the following major recent developments in novel methods and modelling of complex systems for diverse areas of science， scalable scientific algorithms， advanced software tools， computational grids， advanced numerical methods， and novel application areas where the above novel models， algorithms and tools can be efficiently applied such as physical systems， computational and systems biology， environmental systems， finance， and others.

The LNCS Journal on Data Semantics is devoted to the presentation of notable work that， in one way or another， addresses research and development on issues related to data semantics. Based on the highly visible publication platform Lecture Notes in Computer Science， this new journal is widely disseminated and available worldwide.The scope of the journal ranges from theories supporting the formal definition of semantic content to innovative domain-specific applications of semantic knowledge. The journal addresses researchers and advanced practitioners working on the semantic web， interoperability， mobile information services， data warehousing， knowledge representation and reasoning， conceptual database modeling， ontologies， and artificial intelligence.

本书介绍电磁散射的基础理论和技术，包括电磁散射的计算和测量两部分。在计算部分，系统地讲述了当前应用比较广泛的几种计算电磁学方法，如矩量法、有限元法、时域有限差分法、快速多级子算法和有限积分技术。在测量部分，重点讲述测量的基本概念和技术，如近场与远场响应之间的关系、散射测量的仪表系统、紧缩场技术和室外静态场技术。本书主要针对散射研究的历史、现状进行论述，同时也提出了一些作者自己的学术见解供讨论，可作为从事散射研究的科技人员、教师和研究生的教材或者参考书。
