1·Ferrous iron reduces to ferric iron.

二价铁能还原成三价铁。

2·The water was reacting with the ferrous iron in the tank.

水箱中的铁质产生化学反应。

3·Main raw materials: amino acid chelate trace elements, glycine zinc, ferrous iron, manganese, vitamin C carrier: lactose, starch, beef powder.

主要原料：氨基酸螯合微量元素，甘氨酸锌，甘氨酸亚铁，蛋氨酸锰，维生素C 载体：乳糖，淀粉，牛肉粉。

4·The assay is based upon formation of a complex between Xylenol Orange and ferric iron, which is produced by the peroxide dependent oxidation of ferrous iron.

检测方法基于二甲酚橙和三价铁形成的复合物显色反应，而三价铁由过氧化物氧化二价铁得到。

5·This included machinery, carmaking, information technology, construction, iron and steel and non-ferrous metals.

这些行业包括机械装备、汽车、电子信息、建筑、钢铁和有色金属。

6·A sine wave alternating voltage signal is generated synchronously in the presence of gear teeth made of carbon steel, magnetic stainless steel, or iron (ferrous metal).

阿正弦波交流电压产生的同步信号中的齿轮碳钢，不锈钢磁性，或铁(黑色金属)提出的存在。

7·Methemoglobin — the oxidized form of hemoglobin, containing iron in the ferric rather than the ferrous state, that is incapable of binding oxygen.

高铁血红蛋白：血红蛋白的氧化形式，含正铁离子而非亚铁离子，不能携带氧。

8·Because ferrous metals (steel and cast iron) are by far the most widely used metals, coverage of nonferrous metals in these books is cursory or absent.

由于有色金属(钢和铸铁)是目前使用最广泛的金属，报导有色金属这些书籍是粗粗或缺席。

9·Ferrous oxide, is one of iron oxide.

氧化亚铁，是铁的氧化物之一。

10·Proven reserves of ferrous metals include iron, manganese, vanadium and titanium. China's 45.9 billion tons of iron ore are mainly distributed in northeast, north and southwest China.

黑色金属矿产探明储量的有铁、锰、钒、钛等，其中铁矿保有储量为459亿吨，主要分布在东北、华北和西南地区，辽宁的鞍山-本溪一带、河北的冀东一带、四川的攀枝花一带，都是大型的铁矿区。
