The sky looks solid, like a vault of steel set with diamonds!

天空一是那么地坚固，如同一片镶着钻石的钢质穹窿！

The classic vision of the heavens is that of an immense vault, which is beautiful because it stands for order and perfection.

经典的天空视觉是一个巨大的穹窿， 因为它代表着秩序和完善而更显美丽。

While exchanging this chitchat, we entered beneath the dark canopies of the forest, and for two hours we explored it in every direction.

我们彼此说笑话，交换一些意见的时候，我们穿人了森林的阴沉的穹窿下，只有两小时的功夫，我们四面八方都走遍了。

Slanting inward over their base, these high walls converged to form a vault shaped like an immense upside-down funnel that measured 500 or 600 meters in height.

周围的高墙，下，上面是穹窿的圆顶，形状很像倒过来的漏斗，高度为为五百至六百米。

I distinguished the unpredictably contoured springings of a vault, supported by natural pillars firmly based on a granite foundation, like the weighty columns of Tuscan architecture.

我分辨出那些由天然石柱支架起来的、穹窿很宽大的形成轮廓的起拱石，这些石柱的宽大底座安在花岗岩的石基上，像托斯甘式建筑的笨重石柱那样。
