" you see , " said danglars , addressing caderousse , " the turn things have taken “你看， ”腾格拉尔对卡德鲁斯说， “事情变复杂了吧。
Aokamu razor : if not appropriately , don ' t add up the new things . simple and complex rule : it is easy to complex the things , but it is disaster to simplify the things 奥卡姆剃刀：如无必要，勿增实体。简单与复杂定律：把事情变复杂很简单，把事情变简单很复杂。
Switch commonly used to tell a program to read a configuration file complicates the configuration because the file may override or supplement options given on the command line 开关通常用于告诉程序读取一个配置文件，这将因为该文件可能覆盖或者补充命令行上给出的选项而使处理变复杂。
Different parts in the same seamless system perform different tasks , and the use of oo method becomes the key point in the system integration of netfeaf . by making full use of some strategies like " from top to down " , " divide and conquer " and " step by step " , with the help of oo method , netfeaf creates a new method to build the whole integrated system : using one class hierarchy map to fully stand for the structure of netfeaf , and different parts in netfeaf like cluster class library , fea class library , web fea class library and gravity wharf cad class library can also be further explained by their sub class hierarchies , then the complexity of building netfeaf has been decreased step by step , the whole building procedure becomes much easier , so oo method can really change complexity into simplicity Netfeaf系统依据自顶向下、分而治之以及层层推进的实现原则，采用了全新的系统构造思路，对系统的集成用整体类库组成图进行表述，对各组成部分通过子类库再进一步详细介绍，系统的整体实现被一层一层分解、细化，各组成部分基于统一的计算核心集成在同一个系统框架内，同时相互之间还保持一定的独立性，独成一体，正是因为深入利用了面向对象的分析与实现手段，整个复杂系统构成从概念上更有利于理解，集成更加紧凑，具体模块的实现也更加迅速高效，面向对象方法的变复杂为简单的策略艺术在系统的具体实现过程中得到了充分展示。
