catenaries

两端支承的柔性链或绳,在仅受自身重量产生的均匀引力作用(以及涉及附加非均匀力的变化)下所形成的曲线；由双曲余弦函数描述。

The curve described by a flexible chain or a rope if it is supported at each end and is acted upon by no other forces than a uniform gravitational force due to its own weight and variations involving additional and non-uniform forces. It is described by the hyperbolic cosine function.

具有该几何形状的任何物理缆索、绳索、链条或其他承重结构,例如桥梁的悬索、输电线路或桥梁/屋顶的拱。

Any physical cable, rope, chain, or other weight-supporting structure taking such geometric shape, as a suspension cable for a bridge or a power-transmission line or an arch for a bridge or roof.

锚缆从海底到船体的曲线；在锚处应呈水平,以便埋入锚爪。

The curve of an anchor cable from the seabed to the vessel; it should be horizontal at the anchor so as to bury the flukes.

其支承点之间的段呈悬链线几何形状的缆索,用于支承为火车、有轨电车或无轨电车供电的架空接触导线；或(转喻)该导线、缆索和支承物的组合。

A cable, the segments of which between supports take a catenary geometric shape, supporting in turn an overhead conductor that provides trains, trams or trolley buses with electricity, or (metonymic) the combination of the conductor, the cable, and supports.
