时差N小时 为何挡风玻璃如此结实?(下)（在线收听）

Tempered glass shatters into tiny bits, rather than large, jagged shards like regular glass.

破碎后的钢化玻璃为细小的碎块，而普通玻璃破碎后为巨大、锋利的碎片。

If you've seen little squares of a car windshield scattered on the street, you've seen how tempered glass shatters.

如果见过街上散落一地的汽车挡风玻璃碎块，你就知道钢化玻璃破碎后的形状了。

Car windshields are also commonly made from laminated glass, which has a tough, thin layer of plastic sandwiched between two layers of glass.

汽车挡风玻璃常用层压玻璃制成，这种玻璃十分坚硬，两层玻璃间有一层薄塑料，

If laminated glass shatters, it remains sticking to the plastic rather than scattering in splinters or shards.

当层压玻璃破碎后，玻璃碎片会沾在塑料上，不会到处散落。

Airplane windshields and bullet-resistant glass take this concept to a whole new level, with several layers of plastic layered with, and bonded to, layers of glass.

通过将多层塑料夹层和多层玻璃叠压在一起，飞机挡风玻璃和防弹玻璃将层压玻璃的概念上升到了一个新高度。

That makes a composite material strong enough to withstand high pressures, varying temperatures, and even the impact of a bullet or an unlucky bird.

这种复合材料的强度足以高压、温度变化，甚至是子弹与飞鸟撞击飞机的力度。
