Description: 本程序分为界面和控制器核心两部分
一、界面部分功能主要有：
（1）显示控制器核心数据和参数
（2）与用户交互，可以调节初始输入温度值，并将温度变化率清零以便进行新一轮的模拟。
界面使用了定时器。开启模拟时候，每隔一秒，触发一次计时器消息，完成下列工作：
1. 将界面上的当前温度映射为模糊控制器的输入温度
2. 输出当前温度，当前温度变化率
3. 调用模糊控制，得到控制器输出值，将其乘以m_fFuelEffect (燃料输出对温度变化率的影响率，目前设置为0.3)，得到变化率的变化，加到当前温度变化率上，得到新的变化率。
4. 更新变化率，更新温度。将结果映射到界面上。
5. 记录相关数据并以图形、数字方式输出。
二、控制器核心用到的类有
（1）Rule_Func_Single
将简单的函数包装成类，方便后面使用。实现了 NB, NS, ZO, PS, PB 等梯形函数，以及常值函数。
（2）Grading_Func
继承自Rule_Func_Single类，比基类增加一个输入参数，指明梯形函数属于Input, Delta或者Output 。
（3）Rule_Function
将两个Grading_Func结合在一起，进行模糊与或模糊或等模糊逻辑操作，并输出结果。

Description: 我研究生阶段研究定的方向是网络拥塞管理，而我研究RED算法也有挺长时间了，很久以前就有解析NS中的队列管理算法RED的源代码（red.cc&red.h）的想法，借寒假有时间，匆匆写了一下。有些东西自己也没完全弄懂，但是对于困惑于如何修改RED算法的同学来说，应该有很大的参考价值。
本文档首先分析了RED算法涉及参数的含义，然后给出了主要函数的作用，最后对主要函数的源代码进行了分析。
希望本文档对你有用。
-I set the direction of post-graduate stage of the study is to network congestion management, but I have studied the RED algorithm also has quite a long time, long ago have resolved NS in the RED queue management algorithm source code (red.cc & red.h) the idea, by winter have the time to rush to write a bit. Some things they themselves have no fully understood, but for the confusion on how to modify the RED algorithm for the students, it should be a great reference value. This document first analyzes the RED algorithm is related to the meaning of the parameters, and then gives a major role in the function and finally the main function of the source code analyzed. Hope that this document useful to you.

The latter code produces postscript files of each plot page: grid, velocity vectors, profiles of velocity or temperature, isobars, isotherms or streamlines, and color-fill plots of pressure, temperature or streamlines. Change to this directory and read the local 'readme' file for further information on files in that directory.
