====Netlogo模型的基本架构====
Netlogo模型中起着关键作用的是Observer, patch, turtle和link四个功能模块。
Patch是被安放在网格中的，Turtle在网格中运动。Link连接两个Turtle。Observer控制全部的模块。这一点通过命令语言也能够看出，通过直接命令语句能够在对应的模块控制框中修改参量，但是在观察者的控制框中能够通过Ask语句控制其他的三种模块。
这其实是一种比喻的体现。其中的turtle作为structural metaphors，能够以一个简单的图标来模拟其他的不同事物，而事物的性质能够通过一系列函数添加到turtle上，而这些性质是通过功能或者说函数来实现的，netlogo中的tutrtle具有读取数据并且修改数据的功能，因此能够作为一个非常强大的本体载体。通过改变patch我们能够很轻松地修改环境参量，从而建立我们所需要的模型。
Netlogo的语言实际上是一种简化过的计算机语言，具有很高的可操作性和简洁性。在编写程序的时候，程序包含控制流和数据流，那么observer实际上就是控制流，而turtle, patch和link则相当于被控制的模块，数据流很大程度上是通过颜色来实现的，颜色的种类（深浅）代替了不同的数值。Netlogo的语言通过这种简单的架构大大地降低了操作的复杂性。

====程序语言[1]====
{|border=1
|+
|Agents
|Agents are beings that can follow instructions
|-
|Procedures
|Commands and reporters you define yourself are called procedures
|-
|Variables
|Agent variables are places to store values (such as numbers) in an agent
|-
|Tick counter
|In many NetLogo models, time passes in discrete steps, called "ticks"
|-
|Colors
|NetLogo represents colors in different ways
|-
|Ask
|NetLogo uses the ask command to give commands to turtles, patches, and links
|-
|Agentsets
|An agentset is exactly what its name implies, a set of agents
|-
|Breeds
|NetLogo allows you to define different "breeds" of turtles and breeds of links
|-
|Buttons
|Buttons in the interface tab provide an easy way to control the model
|-
|Lists
|Lists allow for the convenient packaging of information in NetLogo
|-
|Random numbers
|The random numbers used by NetLogo are what is called "pseudo-random"
|-
|Turtle shapes
|In NetLogo, turtle shapes are vector shapes.
|-
|Link shapes
|Link Shapes are similar to turtle shapes, only you use the Link Shape Editor to create and edit them
|-
|View updates
|The "view" in NetLogo lets you see the agents in your model on your computer's screen
|-
|Plotting
|NetLogo's plotting features let you create plots to help you understand what's going on in your model
|-
|Strings
|Strings may contain any Unicode characters
|-
|Output
|This section is about output to the scree
|-
|File I/O
|In NetLogo, there is a set of primitives that give you the power to interact with outside files
|-
|Movies
|This section describes how to capture a QuickTime movie of a NetLogo model
|-
|Perspective
|The 2D and the 3D view show the world from the perspective of the observer
|-
|Drawing
|The drawing is a layer where turtles can make visible marks
|-
|Topology
|The way the world of patches is connected can change
|-
|Links
|A link is an agent that connects two turtles
|-
|Tasks
|Tasks let you store code to be run later
|-
|Ask-Concurrent
|The following information is included only for backwards compatibility
|-
|Tie
|Tie connects two turtles so that the movement of one turtles affects the location and heading of another
|-
|Multiple source files
|The __includes keyword allows you to use multiple source files in a single NetLogo model
|-
|Syntax
|In the Code tab and elsewhere in the NetLogo user interface

====有趣的发现====
#一般的软件都只会提供用户手册，但是Netlogo的帮助栏中还多了一项Netlogo辞典。'''[2]'''这是非常有趣的。点进去可以看到其根据字母、种类以及特殊进行了初步分类，然后再每一种具体列出。在数量少的时候，词条或者说词典的作用显现不出来，但是一旦内容多了，一个有序的词典的重要性便被凸显出来，这个词典无疑能够帮助我们快速地掌握netlogo中的一些词条，从而较为轻松的跨越incomesurability。这也是顾老师为什么让我们写词条的原因。词条的力量是强大的！
#Netlogo的Maunual book的网页的架构和wiki相似，整个网页的编辑都感觉像是在编辑wiki。
