And we're spreading about 30,000 tons of silicate rock every month now.

而我们现每个月都要播撒大约3万吨的硅岩。

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

如此外观，得益于行星表面的大气层，主要构成物质为硅颗粒。

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

的奇妙外观是由于这个行星的大气主要由硅颗粒、厚砂或玻璃组成。

Some kind of silicate in the atmosphere.

大气中有某种硅。

The researchers studied eight particles from Ryugu and found phyllosilicates, which are formed by chemical reaction between non-aqueous silicate minerals and liquid water, indicating that liquid and frozen water were both present.

研究人员通过研究 8 颗“龙宫”沙粒，发现其中均存页硅，是通过非含水硅矿物和液态水的化学反应形成，表明“龙宫”上或存过液态水和冰冻水。

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矿石。

Using the serial analysis method, researchers obtained space weathering information of silicates, oxides, phosphates and sulfides on the surface of a single particle of lunar soil collected by Chang'e-5.

利用系列分析方法，研究人员获得了嫦娥五号采集的月球土壤单个颗粒表面硅、氧化物、磷和硫化物的空间风化信息。

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。

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，主要是硅冰核。

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，形成坚硬的硅外壳覆盖铁镍内核之外。

Martian samples found deposits of minerals very similar to those in Spotted Lake, including magnesium and sodium salts and silicates.

火星样本中发现的矿物质与斑点湖中的非常相似，包括镁、钠和硅。

Silicates also include quartz and most types of clay and they're found in living things, like little spikes and nettles.

硅还包括石英和多种粘土，生物也含有硅，比如幼鲐和荨麻。

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.

然后其中一些变得像沙石大多是小块的硅石头，们又不断地融合其他小石块。

Oxides of silicon, known as silicates, make up sand, which covers not only every desert and shoreline on the earth, but also most of the ocean floor.

硅、氧和其他金属构成的化合物称为硅，组成了沙子，地球上每一处沙漠和海岸线，以及大多数的海底区域都存硅。

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

撞击后，新生行星的硅冰核与木星的硅冰核融合，导致木星的核心变得稀疏。

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。
