毕竟，太阳中任何元素的原子，比如说铁，都比陨石标本的原子要多得多，但这两种物质中铁和硅的比例可能是可以比较的。

After all, the Sun has many more atoms of any element, say iron, than does a meteorite specimen, but the ratios of iron to silicon in the two kinds of matter might be comparable.

月球的土壤(风化层)含有铁、铝、钙、硅、钛和氧等元素，此外还发现有大量较轻元素如碳、硫和氮等。

The lunar soil (regolith) contains iron, aluminum, calcium, silicon, titanium, and oxygen, as well as trace amounts of lighter elements such as carbon, sulfur, and nitrogen.

第二丰富的元素是硅，占到27%，再其次是铝、占8%，铁5%，钙4%。硫、钾和镁每种占大约2%。

The second most abundant element is silicon at 27 percent, followed by aluminum at 8 percent, iron at 5 percent, calcium at 4 percent, and sodium, potassium, and magnesium at about 2 percent each.
