长期以来中国的信息科学与信息实践存在严重的脱节问题，虽然信息分析与情报研究广泛应用于各个领域的历史相当久远，但信息分析始终并未形成独立的学科体系，因此难以进一步的发展，并对中国未来的竞争实践构成了现实威胁。 为了使信息分析和情报研究能够有效地面向未来，作者结合日常分析工作，通过历时一年半的研究和写作，提出了信息反射论、思维训练、知识能力、信息链和策略研究等一连串的基础理论概念，引入了必要的方法体系和基本原则，批判性地挑战了长期以来信息科学的传统观点，并在此基础上，首次明确提出并构筑形成了信息分析学的基本概念和理论基础。 应该说，这是一部来自于专业研究人员的著作，是来自于现实的作品，非常务实且具有可操作性。

This book is intended as a textbook for a first course in the theory offunctions of one complex variable for students who are mathematicallymature enough to understand and execute arguments. The actual pre-requisites for reading this book are quite minimal; not much more than astiff course in basic calculus and a few facts about partial derivatives. Thetopics from advanced calculus that are used (e.g., Leibniz's rule for differ-entiating under the integral sign) are proved in detail.
