If you were to slice a real igloo in half, you'd see a shape called a catenary.

如果把真正的冰屋分成两部分，你可以看见线的形状。

A catenary arch distributes weight more evenly than a half circle, without bulging or buckling.

状比半圆更能承受住量，并且不会被压。

All cables sag under their own weight, following a curve called a catenary.

所有电缆都在自身量的作用下下垂，遵循一条称线的曲线。

It's set to host about 3,000 employees and is dominated by a huge aircraft-hangar-inspired catenary roof that forms its main structure.

它将容纳约 3,000 名员，并以构成其主要结构的巨大飞机机库灵感的屋顶占据主导地位。

If you know the weight of the cable, you can use the catenary equation with the measured sag distance to estimate cable force fairly accurately.

如果您知道电缆的量，则可以使用线方和测量的垂距来相当准确地估计电缆力。

If you watched my video about the science of igloos, you remember that this shape, called a catenary arch, distributes tension and compression more evenly than a half circle shape.

如果你看我关于冰屋原理的视频，那么你会记得这种称线拱的形状比半圆形更均匀地分布张力和压力。
