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

这些微小的颗粒含有硅酸盐、氧化铝和钙等物质。

Three dimensional silicates can take lots of shapes, too.

三维硅酸盐也有许多结构。

It looks this way because the planet's atmosphere is made up primarily of silicate particles.

此外观，得益于行星表面的大气层，主要构成物质为硅酸盐颗粒。

So each silicate is bonded to 4 oxygens, while each oxygen is bonded to 2 silicons.

所以每个硅原子与四个氧原子成键，而每个氧原子也都与两个硅原子成键。

After the impact, the infant planet's silicate ice core merged with Jupiter's, causing Jupiter's core to become diluted.

，新生行星的硅酸盐冰核与木星的硅酸盐冰核融合，导致木星的核心变得稀疏。

9 billion years ago, the Earth cooled, forming a thick silicate crust over its mantle, an iron and nickel core.

39亿年前地球开始冷却，形成坚硬的硅酸盐外壳覆盖在铁镍内核之外。

Some kind of silicate in the atmosphere.

大气中有某种硅酸盐。

It's believed that one such planet was 10 times the mass of Earth, and it was mainly a silicate ice core.

据信其中一颗行星的质量是地球的10倍，它主要是硅酸盐冰核。

It's fantastic appearance is due to the fact that the atmosphere of the planet consists mainly of silicate particles, thick sand or glass.

它的奇妙外观是由于这个行星的大气主要由硅酸盐颗粒、厚砂或玻璃组成。

Cosmic dust is really just very small particles in the universe that are consisting of just a few molecules, often containing carbon or silicate.

宇宙尘埃实际上是宇宙中非常小的粒子，仅由几个微粒组成，通常含有碳或硅酸盐。

Now get this: a lot of Europa's material is silicate rock, like on Earth and other terrestrial planets, located in a layer under the ocean.

和地球及其他类地行星一样，木卫二的海洋底下的主要成分是硅酸盐矿石。

And eventually some of these pieces became more like sand, little pieces of silicate mostly, and it began to stick together and you begin to get little rocks, little boulders.

然其中一些变得像沙石大多是小块的硅酸盐石头，它们又不断地融合其他小石块。

And it depends on which layer you're talking about! The crust and mantle are rock and contain a lot of silicate – which is the same stuff that glass is made of.

它取决于你说的是哪一层！地表和地幔由岩石和硅酸盐组成，硅酸盐是玻璃的组成物质。

It is composed of what sounds like a bizarre mixture: fly-ash, a fine-grained waste product from coal-fired power stations; carbon nanotubes, cylindrical molecules made of elemental carbon; and two binding agents, sodium silicate and sodium hydroxide.

煤灰，火力发电厂排放的细颗粒废弃物；碳纳米管，即柱状的碳分子；还有两种黏合剂：硅酸钠和氢氧化钠。
