Ferrovanadium is a kind of important transitional metal alloy for the tool steel,refractory steel.

钒铁是生产工具钢、耐热钢的一种重要中间合金，目前主要采用铝热法生产。

In Europe, 70- to 80-percent ferrovanadium softened last week to $32 to $34.50 per kilogram from $34 to $35.50 per kg previously.

在欧洲市场，70-80%的钒铁价格从上周的34.5-35.5美元/公斤下降到目前的32-34美元/分手。

However, he said that spot ferrovanadium prices, which he pegged at $13 to $13.25 per pound, haven't softened too dramatically due to increased demand from the steel industry.

不过，他也说，由于钢铁行业的需求增加了，钒铁现货价格在13-13.25美元/磅，并没有太明显的软化。

The mainly preparation of ferrovanadium is aluminothermic reduction currently.

钒铁是生产工具钢、耐热钢的一种重要中间合金，目前主要采用铝热法生产。

The results of experiment show that the Si-V coupled reaction equilibrium can be transferred towards the direction of high temperature and the speed of VO reduction reaction is accelerated sharply by the use of plasma,The technology of plasma can be used to melt ferrovanadium and similar ferroalloys.

试验证明，在等离子条件下，Si－V耦合反应的平衡能向高温方向移动，VO还原速度急剧提高，存在着用碳还原法代替金属热还原法冶炼钒铁和类似的铁合金的可能性。

Vanadium pentoxide and iron quality is better than similar national standards, long-term exports of European countries by users.

五氧化二钒及五零钒铁质量优于国家同类标准，长期出口欧洲各国，深受用户好评。

The titanomagnetite is characterized by low content of chadacryst minerals, high content of iron and low content of titanium, therefore high quality vanadium-iron concentrate with high iron and low titanium could be obtained.

钛磁铁矿具有客晶矿物含量低、铁高钛低的特点，可获得高铁低钛的优质钒铁精矿。

This paper introduced the market development trend of vanadium products(include ferro-vanadium and vanadium oxide).

介绍了钒产品的市场发展趋势，重点从2005年的45万元/t的钒铁历史高价开始分析，到近两年的市场平淡、平稳的原因，并且对从中反射出来的规律进行了总结。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
