Much of the book is about their practical problems-thrust lines, the catenary curve and groin vaulting.
该书大部分都是关于他们实际存在一些的问题—外扩的线条，垂曲弧，穹型拱顶。
Once all 'pairs' are found, I compute the catenary curve and create the cable geometry, either for plain cables or cables with hanging clothes.
一旦所有的配对都找到，我便通过计算垂曲线来创建线缆几何，无论是普通电缆还是晾衣绳都样的。
Moreover, the curve can represent hyperbolas and catenary exactly.
此外，它可以精确表示双曲线和悬链线。
In this paper, the curve and fabrication length of the main cable which is modelled through catenary elements are calculated with the iterative method.
本文用悬链线单元模拟主缆，通过选代计算了主缆的线形及下料长度。
The catenary's shape influenced by gravity is curve, and the pantograph-catenary contact force changes regularly with pattern during one span.
在重力作用下的接触网是悬链形，弓网接触力在一个跨距内呈现规律的起伏变化。
The catenary's shape influenced by gravity is curve, and the pantograph-catenary contact force changes regularly with pattern during one span.
在重力作用下的接触网是悬链形，弓网接触力在一个跨距内呈现规律的起伏变化。
