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越金属管道和周围岩石之间的界面。

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

它带回的照片更加详细，向我们展现了一个飞行的山状物，一个大小15 x 8的不规则块体。

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

由于这一裂口，壳块体在平行断层脊之间滑落。

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

如今， 有百种不同的块体金属玻璃（BMGs）问世，那么何我们的桥梁和汽车并未全部采用这种材料呢？

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， 压碎了紧实的面，向外爆裂，碎裂成参差不齐的不规则块体， 尖啸着飞散到大气中。

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）是由昂贵的金属如钯和锆制成，且必须极纯净，因任何杂质都可能导致结晶。
