In this paper it is argued that far from ignoring geometric and metric properties the ‘line graph’ internalises them into its structure of the graph and in doing so allows the graph analysis to pick up the nonlocal, or extrinsic, properties of spaces that are critical to the movement dynamics through which a city evolves its essential structures.

本文认为，轴线图并没有忽视几何与米制距离特征，而把它们内化与图的结构中。这样的做法使轴线图分析能够揭示出空间的“非局部的”特征，它对城市空间运动而言非常关键，也是城市基础结构演进的基石。

Nonlocal properties are those which are defined by the relation of elements to all others in the system, rather than those which are intrinsic to the element itself. The method also leads to a powerful analysis of urban structures because cities are essentially nonlocal systems.

非局部特征指的是那些由元素与整个系统元素发生关系所定义的特征，而不是仅限于元素本身内在的特征。方法还导向了对城市结构的一个强有力的分析，因为城市的本质是非局部性系统。
