发明是发明人的一种思想结晶，这种思想结晶可以在实践中解决技术领域里特有的问题。科技小发明是指少年儿童在日常生活、学习、劳动中，利用已有的科学技术知识对使用起来感觉不称心、不方便的物品或方法加以改进、改革和创新，设计、制造出具有创新性，使用起来更称心、更方便的新物品或者新方法。科技小发明是新型实用的身边科学。全国青少年科技活动领导小组对科技小发明的主要项目做了明确规定：第一，发明，指一切具有新颖性、先进性和实用性的科技成果；第二，改进和革新，指对原有物品的形状、构造或其他方面提出的改进技术方案；第三，新品种，指人工培育的动植物新的品种；第四，发现，指对前所未知的事物、现象及其规律的揭示。少年儿童通过科技小发明可以参加青少年科技创新大赛、宋庆龄少年儿童发明奖和明天小小科学家等竞赛活动，但随着人工智能时代的到来，依靠传统的小发明作品在现在的竞赛活动中很难获得理想的名次。因此，把人工智能知识融入科技小发明作品中是提高作品质量的重要途径。这就是本书编写的初衷：帮助孩子们学习如何从头到尾完成一个科技小发明作品的全过程，即包含确定课题、制订方案、制作模型或者原型、优化改进、撰写研究报告等内容。通过本书，旨在让更多的人喜爱这个活动，参与这个活动，扩大这个活动，助力全民创新热潮。由于编者水平有限，书中难免有疏漏和不足之处，恳请广大读者批评与指正。

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.
