So, where is he getting all this silicon necessary to make the sand?

那么，他要从哪弄到这些必要的硅元素来子？

Astronomers identified the silicon-rich rocky material by training the Hubble Space Telescope on the nearby Hyades star cluster.

天文学家通过培训哈勃望太空远镜观测附近的毕宿星团来确认富含硅元素的岩石物质。

Usually transistors are made with the element silicon. But the scientists say they use materials that have even better electronic properties.

通常晶体管是由硅元素成，但科学家称使用了有更好电子性能的材料。

Such a tiny simple device made mostly from one single element, and yet revolutionizing our entire world.

这样一个小小的简单的装置主要只由硅这一个元素构成，但对我们的整个世界有革命性的影响。

The Earth is made up of iron, nickel, magnesium, silicon, and smaller concentrations of other elements.

地球由铁、 镍、 镁、 硅少量其他元素组成。

We're carbon-based lifeforms because there's a lot of carbon on Earth, but perhaps on another planet, something like silicon is the most abundant element, and therefore life could evolve from that.

人体的主要构成元素是碳，因为地球上有很多碳，但或许在其他星球上就不是这样。其他星球上大量存在的可能是硅元素，那么外星生命就是以硅元素为基础的。

And when we say organocatalyst or organocatalysis, we mean that the catalyst is a small and well-defined organic molecule that consists mainly of elements such as carbon, hydrogen, oxygen, nitrogen, maybe, sulfur, phosphorus, silicon, but no metals.

当我们说有机催化剂或有机催化时，我们的意思是催化剂是一种小而明确的有机分子，主要由碳，氢，氧，氮，也许还有硫，磷，硅等元素组成，但没有金属。
