Why Your Phone Screen Feels So Smooth — The Science of Gorilla Glass

课文

1. Most modern phone screens use chemically strengthened glass called Gorilla Glass.

   大多数现代手机屏幕采用一种名为‘大猩猩玻璃’的化学强化玻璃。

2. Engineers dip ordinary glass into a hot potassium salt bath for several hours.

   工程师将普通玻璃浸入高温钾盐浴中数小时。

3. Smaller sodium ions in the glass surface get replaced by larger potassium ions.

   玻璃表面较小的钠离子被较大的钾离子取代。

4. This creates compressive stress that makes the surface much harder to scratch.

   这会在表面形成压应力，使其更耐刮擦。

5. The process also prevents tiny surface cracks from spreading easily under pressure.

   该工艺还能防止微小表面裂纹在压力下轻易扩展。

6. Unlike plastic coatings, this strengthening happens throughout a thin outer layer.

   与塑料涂层不同，这种强化作用遍及一层薄薄的外层。

7. Each new generation improves resistance to drops, abrasion, and even oil stains.

   每一代新品都在抗跌落、抗磨损甚至抗油污方面有所提升。

8. Manufacturers test durability by dropping phones onto rough concrete from increasing heights.

   制造商通过将手机从不同高度反复摔向粗糙水泥地来测试其耐用性。

9. Because it’s transparent and tough, Gorilla Glass enables thinner, lighter, and more responsive touchscreens.

   由于透明且坚固，大猩猩玻璃使触摸屏得以做得更薄、更轻、响应更快。

10. Its invention shows how materials science solves real-world problems without users noticing.

    它的发明体现了材料科学如何在用户无感的情况下解决现实问题。
