These tiny grains contain things like silicates, aluminum oxide, and calcium.

这些微小的颗粒含有硅酸盐、氧和钙等物质。

But when aluminum reacts with oxygen, it forms aluminum oxide, which is non-reactive and protects the pure metal underneath.

但是当与氧气反应时，会形成氧，是非反应性的，可以保护下面的纯金属。

And the aluminum oxide starts to grow out of the plane like some kind of cyberpunk plant.

氧开始像某种赛博朋克植物一样从飞机长出来。

So scientists can make coatings that have things like aluminum oxide nanoparticles in them, to make surfaces rougher and repel water.

科学家们可以制造物质表层，例如包含氧纳米粒子的材料，让物体表层粗水。

A silica and aluminum oxide powder acted as a stand-in for lunar dust.

二氧硅和氧粉末充当了月球尘埃的替代品。

When that amalgam meets the air, it stills turns into aluminum oxide — except this time, because there's mercury involved, the reaction doesn't stop.

当这种汞合金遇到空气时，仍然会变成氧——除了这次，因为有汞，反应不会停止。

Fan and colleagues used a curved aluminum oxide membrane, studded with nanosize sensors made of a light-sensitive material called a perovskite, to mimic that architecture in their synthetic eyeball.

Fan 和他的同事使用了一种弯曲的氧膜，面镶嵌着由一种叫做钙钛矿的光敏材料制成的纳米级传感器，以在他们的合成眼球中模拟这种结构。

See, the team coated their diamonds in aluminum oxide to keep them from breaking, and it’s possible that the shiny stuff they saw was metallic aluminum oxide, not metallic hydrogen.

看，该团队在他们的钻石涂氧以止们破裂， 他们看到的闪亮物质可能是金属氧， 而不是金属氢。
