Martin Fowler和《重构:改善既有代码的设计》(中文版)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。《重构:改善既有代码的设计》(中文版)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。《重构:改善既有代码的设计》(中文版)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。某些项目如Extract Method和Move Field看起来可能很浅显，但不要掉以轻心，因为理解这类技术正是有条不紊地进行重构的关键。-Martin Fowler, " Refactoring: Improving the Design of Existing Code"　(Chinese version) Another Several authors have clearly revealed the reconstruction process, their contribution to object-oriented software development, it is difficult to measure. " Refactoring: Improving the Design of Existing Code"　(Chinese version) to explain the reconstruction of the principle (principles), and best practices (best practices), and point out when and where you should begin to dig through your code in order to improve. " Refactoring: Improving the Design of Existing Code"　(Chinese version), the core of a complete reconstruction of the directory (catalog of refactoring of), each of which introduces an empirical code transformation techniques (code transformation) motivation and technology. Certain items, such as Extract Method and Move Field may seem very simple, but do not be taken lightly, because understanding of such technologies is the orderly conduct of the reconstruc
