说明：  《重构[改善既有代码的设计中文版]/软件工程系列》中文版，侯捷等译，Martin Fowler和本书另几位作者清楚揭示了重构过程，他们为面向对象软件开发所做的贡献，难以衡量。本书解释重构的原理（principles）和最佳实践方式（best practices），并指出何时何地你应该开始挖掘你的代码以求改善。本书的核心是一份完整的重构名录（catalog of refactoring），其中每一项都介绍一种经过实证的代码变换手法（code transformation）的动机和技术。
(" Reconstruction [to improve the design of both the Chinese version of the code]/Software Engineering Series" the Chinese version, Hou Jie, such as translation, Martin Fowler and several other authors of this book clearly reveals the remodeling process, they are object-oriented software development by contribution to make, difficult to measure. Reconstruction of the book to explain the principles [principles] and best practices [best practices], and pointed out that when and where you should start digging your code to make improvements. This book is the core of a complete remodeling List [catalog of refactoring], each of which introduce a code transformation through empirical methods [code transformation] of the motives and techniques.)
