文档介绍：歌特大教堂的最著名,也是最易区别于其他风格教堂的三个特点,一个就是尖拱(Pointed Arch),一个是飞扶壁(Flying Buttress),还有拱肋(Ribs).(there are three most famous and distinctive features of the cathedral: pointed arch, flying buttress and ribs.)
 
I:首先是关于拱(ARCH),以下是一些关于拱的相关词语,有助于我们更深入详细的了解(here is some keys words for Arch)
(拱顶石) - the central stone of an arch or vault. 位于拱或者拱顶的中央的石头

(起拱点,拱墩) - the part of the arch's wall (usually molding) on which the arch rests. 拱落脚的那一段拱墙(通常是线脚)
- the part of the arch's wall which balances the force of gravity the arch makes (thrust) .拱墙上用于平衡拱的重力(一个推力)的部位

(跨度) - the width of the arch's opening. 拱的宽度
(冠) - the top part of an
(拱角) - the part of the arch's wall which experiences the most thrust. 拱墙承受推力最大的地方

在了解了这些基本知识以后,我们就进入下一步:拱的分类
如同在上一PART里说的”歌特式建筑的一个重要特征便是它的pointed arch,, Equilateral 和Ogee.”(as is said in
Part 2, the pointed arch is one of the unique feature of Gothic architecture. The mon gothic arches are Lancet, Equilateral and Ogee.)
以下就是各式ARCH的简图,这个作为一个简单的了解即可,不用深究:
这个就是标准的Gothic (Pointed)拱
 
Ogee: The double-curve ogee (oh-jee) was introduced from the Arab world in the 14th century and became popular throughout medi England. It was also a favorite in Venice, Italy from where it derived its other moniker - the ian arch. It can also be referred to as a keel arch for its apparent resemblance to ship :双曲线Ogee是十四世纪从阿拉伯引入的,,它也十分受欢迎,并在那里获得了一个别名:,它也可以被称作龙骨拱.

II:拱肋(RIBS)
哥特式教堂的结构体系由石头的拱肋(RIBS)和飞扶壁(FLYING BUTTRESS)组成的,我们先从拱肋认识起.
 
拱肋的构造一般来说其基本单元是在一个正方形或矩形平面四角的柱子上做双圆心骨架尖券,四边和对角线上各一道,屋面石板架在券上,形成拱顶。采用这种方式,可以
