Those pictures were more detailed, and showed us a flying mountain, an irregular chunk 15 x 8 kilometers in size.

它带回照片更加详细，向我们展现了一个飞行山状物，一个小为15 x 8公里不规则块体。

And then, as those chunks get even bigger, gravity starts to kick in and attract even more stuff.

当这些块体变得更时，引发挥作用，吸引更多物质。

This means a block can straddle, say, the interface between a metal pipe and the rock surrounding it.

这意味着块体可以跨金属管道和周围岩石之界面。

And then, over millions of years, all of the stuff in that disk keeps smashing together and forming into bigger chunks of stuff.

随后，在数百万年时里，这个盘中物质不断相互碰撞，逐渐形成来块体。

Smoked them so that they crumbled, crushed outward through the hard-packed ground, broke up into jaggedly irregular blocks which hurtled screamingly away through the atmosphere.

烟雾使得它们（火山口壁）崩塌， 压碎了紧实地面，向外爆裂，碎裂成参差不齐不规则块体， 尖啸着飞散到气中。

Now, there are hundreds of different BMGs, so why aren't all of our bridges and cars made out of them?

如今， 已有数百种不同块体金属玻璃（BMGs）问世，那么为何我们桥梁和汽车并未全部采用这种材料呢？

Due to this opening, the blocks of crust slip down between the parallel ridges of the faults.

由于这一裂口，地壳块体在平行断层脊之滑落。

Many of the BMGs currently available are made from expensive metals, like palladium and zirconium, and they have to be really pure because any impurities can cause crystallization.

目前市面上许多块体金属玻璃（BMGs）是由昂贵金属如钯和锆制成，且必须极为纯净，因为任何杂质都可能导致结晶。
